Best Air Purifiers for Pet Hair

These brands will help eliminate hair, odors and dander from the air in your home.

Most people love their pets…and I mean love.

The problem is that, for some people, their pets don’t love them back. No, I’m not talking about not showing affection or providing companionship. I’m talking about those people that suffer from pet-related allergies. Who would have thought that you could be allergic to the ones you love?

So, what is someone to do in a case like this? You wouldn’t want to get rid of your pets, but at the same time being able to breathe is kind of nice…right?

This is where the use of an air purifier that is geared towards removal of pet hair, odors, and dander comes into the picture.

To be fair, there is nothing that will completely remove any and all pet-related allergens from the air, but a good quality air purifier is certainly a great supplemental strategy to help ease the symptoms…and, your pets can stay at home!

We have tested the best air purifiers available for pets. These brands will help to eliminate hair, odors, and dander from the air in your home.

Which Air Purifier Type is Best For Pets?

As with many things in life, the answer is…”it depends”.

For dander, a HEPA filter would most likely be the best way to go. This is due to the filtration capacity with those smaller particles. Odors are best handled by the absorption properties of a good activated carbon filter, and a pre-filter may be the best to handle hair.

Put it all together and the answer may be clear – a good multi-stage air purifier that has all three components may be the best at removing all of the hazards your pets can produce.

Household Pets & Air Purifiers – What To Consider

To answer this properly, we need to consider what it is about our pets that can trigger allergies or otherwise create discomfort. From there we can look at which of the filtration types may be best at removing those hazards.

Pet Dander

Common pet problems in the home can be caused primarily by pet dander. The American Lung Association gives a great description of what exactly “pet dander” is:

Pet dander is composed of tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers. These bits of skin can cause reactions in people who are specifically allergic to these triggers.

It’s common to hear of people being allergic to certain pets. Some may be more prone to having problems with dogs, and others with cats. As noted, though, even bird lovers are candidates as well!


Time for a harsh reality – your pets stink. Literally.

I’m not talking about those times where your dog comes back in from roaming around outside and smells like an absolute cesspool. (Got to be objective here though from the dog’s point of view. I mean, really…who doesn’t think that going outside and rolling around in whatever-is-on-the-ground isn’t just the greatest idea in the world?)

I’m talking more about just the natural odor that pets produce. You may love your basset hound, but even after he (or she) gets a bath it doesn’t take long before they just have that “dog smell”.

People tend to think of dogs mostly in this regard, but no animal is immune from this. Cats and birds can have an odor that can “funk-ify” just about any room, just as well as any dog!


The hair coming from some pets is small enough where it can become airborne as well. Maybe not so much as dander, but it can be an issue. This is why many multi-stage air purifiers have a “pre-filter” stage that gets these larger contaminants out of the air first, saving the HEPA and other stages to do the real “dirty work” (no pun intended…but you have to admit that’s pretty funny…)

Dogs Vs Cats

A common misconception is that the hair of animals is the actual cause of allergies in humans. The dander within the hair actually carries all the nasty elements that can disrupt our lives. Cat hair is generally finer than dog (and human) hair so purchasing an air purifier with added filter stages is recommend if you own a cat.

Dog owners who are looking for an air purifier in their homes may be able to get away with less filtration than those with cats. We would recommend getting a model that covers larger areas if your dog is roaming all over the house.

7 Best Air Purifiers for Pets Reviewed

1. Rabbit Air MinusA2 – Best Air Purifier for Pet Dander

Coverage Area (sq. ft.) 815
Filtration Type Six-stage
Filtration Life 12 months
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 45.6
Warranty 5 Year limited

The Rabbit Air Minus A2 Air Purifier has such impressive feature and benefit sets, it has well earned its place at the top of our list for the best air purifier for pet related issues.

Where do we start? With so much to offer this unit may be hard to beat!

The coverage area is an impressive 815 sq. ft. – more than enough for a typical room size. And, it will clean your air with an amazing six stages of filtration:

  • Pre-filter (for the bigger stuff)
  • Medium filter (for the little bit smaller stuff)
  • BioGS HEPA filter (for the really tiny stuff)
  • Customized Filter Stage (choose from germ defense, pet allergy, odor remover, or toxin absorber
  • Activated carbon (stink no more!)
  • Negative Ion Generator (little blast of ionic capacity just to seal the deal)

The BioGS HEPA filter isn’t your typical HEPA element, as it has the technology to reduce the number of bacteria and viruses that may grow over time.

The effectiveness of the filtration is the main selling point here, for sure. But you shouldn’t overlook the other features that helped to make this our #1 choice.

The design was meant to be extremely functional, with desktop or wall mount options available. You can also customize the front panel with several types of graphics to accommodate any room décor.

Operation via the Rabbit App is a step above as well. All of the functions can be controlled remotely via your smartphone, including setting up a programmable schedule for operation. You can even adjust the level of the LED lighting and reorder filters – all straight from the app!

Top all of that off with a generous 5-year warranty and it’s plain to see why the Rabbit Air MinusA2 is our recommendation for the best air purifier for pets.

Filtration Life 1 year approx.
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 26 (low setting)
Warranty 2 year manufacturer

The third option on our list is the Winix HR90 Ultimate Pet.

This unit, while rated for a smaller area with a coverage area of 283 sq. ft., may be the unit of choice for you if you have a smaller room and you have a pet that tends to shed.

Using a five-stage filtration process, any pet hair that becomes airborne (yes…pet hair can actually float around in your room) is sure to get trapped and taken out of commission. Not only hair, but pet dander and odors are trapped as well.

The first stage is a washable pre-filter, followed by a true HEPA filter element for fine particulate removal. From there the air passes through the CleanCel anti-bacterial stage to clean the air even further.

The last two stages are made up of a granular carbon filter element to aid in odor control and removal along with Winix’s PlasmaWave technology. The PlasmaWave filtration step is unique in that it immediately neutralizes VOC’s, bacteria, and gases without the use of potentially hazardous ozone.

Operation (even an automatic mode) can be easily made from anywhere in the room with the handy remote control, and the one-year limited warranty is a nice touch to top things off.


  • Five stage filtration process
  • CleanCel anti-bacterial stage
  • PlasmaWave (ozone free) technology
  • Convenient remote control
  • Automatic mode


  • Difficulty getting replacement filters
  • May emit a chemical odor

4. Okaysou AirMax8L – Compact Air Purifier for Pets

Coverage Area (sq. ft.) Up to 800 sq ft
Filtration Type Ultra-Duo Filtration
Filtration Life 6-8 months
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 51 dB
Warranty 5 Years

The Okaysou AirMax8L is the best compact air purifier for pets. I call this air purifier “small but mighty” because it really does a fantastic job of removing all the icky stuff from the air, especially pet odors. I personally keep this model in the hallway right outside my laundry room, where not only my kids have all their stinky sports equipment, but it’s also where the litter box resides. And now, instead of having to mask the stench with air fresheners and fragrances, the odors are just eliminated altogether.

This Okaysou model is rated for rooms up to 800 square feet, but using it in smaller spaces will only make it more efficient. In fact, in areas of up to 320 sq ft, this portable air purifier will circulate the air up to five times per hour.

A lot of customers appreciate how quiet this unit is. At the highest setting it only reaches 51 decibels, which is comparable to elevator music. And in sleep mode, at 22 dB, you won’t hear it at all. There have been several times when I’ve had to put my hand over the fan to make sure it was actually on because I couldn’t hear it!

A 5 year warranty backs this air purifier, and air filters are readily available on Amazon. There is a filter indicator light that will let you know when it’s time to swap them out (about every 6 months), so I recommended having a few on hand.

You can read our full review of the Okaysour AirMax8L here.


  • Affordable
  • Fantastic odor removal
  • 5 year warranty
  • Filter indicator light
  • Intuitive panel design


  • Longest timer is 8 hours
  • Larger size

5. Veva 8000 Elite Pro Series – Best Budget Option

Coverage Area (sq. ft.) 325
Filtration Type Two-stage
Filtration Life 6 to 8 months
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 54
Warranty 2 year limited

If your budget isn’t what you’d like it to be (and really…who’s is?), then the Veva 8000 may be just the air purifier that you are looking for. Powerful enough to clean 325 sq. ft. this unit is simple enough to provide effective operation while not breaking the bank…or, more importantly, your bank!

The two-stage filtration process is comprised of “the big two” – HEPA and activated carbon. These are the two filtration types that are found in the vast majority of air purifiers on the market today, and with good reason. The HEPA element will put a huge dent in the amount of pet dander that’s circulating through your room, and the carbon filters (not just one…but four of them) help to get rid of that “pet smell” that you just can’t ever really avoid.

The Veva 8000 has a three-speed fan, which is impressive for a unit in this price range. No, it doesn’t have an automatic mode or any sort of remote control, but it delivers what it needs to for the price.

The two-year warranty also shows that Veva believes in the quality of its products.

The Veva 8000 – for the price you really don’t have much to lose, and you may be impressed by what you have to gain.


  • Cost efficient price
  • Compact design
  • 325 sq. ft. coverage area
  • Four carbon pre-filters
  • Three fan speed settings


  • Airflow may be weak
  • No filter change indicator

6. GermGuardian AC5250PT – Best Small Room Air Purifier for Pet Allergies

Coverage Area (sq. ft.) 180
Filtration Type Four stage
Filtration Life 6 to 9 months
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 60
Warranty 5 year limited

Sometimes the area you are wanting to clean just isn’t that big. In particular, a bedroom. Some people love to have their pets sleep in the same room…some even don’t mind the pets jumping in bed with them!

The GermGuardian AC5250PT is a great option for those smaller spaces where exposure to pet dander and other hazards can’t be avoided.

Small but well designed, the AC5250PT houses three of the four stages (pre-filter, HEPA, and PetPure anti-bacterial stage) into one convenient, replaceable package. No more guessing when to change the HEPA or the carbon filter – do them both at once, and you do it when the handy filter change indicator tells you to.

The final stage uses UV-C technology in an efficient and safe manner to act as the last defense against airborne pet contamination. This stage can also be turned on and off as you choose.

A timer function along with a multi-speed fan will keep your air as clean as you need it, but an automatic mode would be a nice feature to have.

Add in the five-year limited warranty, and it should be easy to see why the GermGuardian AC5250PT is our pick for the best small room air purifier for pet allergies.


  • Three stage combination filter
  • UV-C element can be operated independently
  • Timer and multi-stage fan settings
  • Five year limited warranty


  • Durability concerns
  • Can’t adjust light levels

7. Airmega 400 – Best Large Room Air Purifier for Pets

Coverage Area (sq. ft.) 1,560
Filtration Type Three stage
Filtration Life Up to 12 months
Particle Removal Capacity 99.97%
Maximum Noise Levels (dB) 52
Warranty Five year limited

It’s not uncommon for pets to be considered members of the family – so much so that they typically have free reign across the whole house (with maybe a few rooms off limits). That can mean you may have a pretty large area where you need to get rid of pet dander.

With an extra large coverage area of 1,560 sq. ft., the Airmega 400 is a great fit for when you have a larger space to clean and you don’t want to resort to using multiple purifiers throughout your home.

The Airmega 400 offers a three-stage filtering process:

  • Reusable pre-filter
  • Max2 filter package that combines true HEPA with activated carbon

There’s no guesswork with filter changes thanks to the integrated filter change indicator. That combined with the convenience of the Max2 combination filter makes maintenance a breeze. The pre-filter is washable as well.

You can “set it and forget it” thanks to the SmartMode – this alters the fan speed without any input based on feedback from the internal air quality monitoring system (which has a visual indicator as well to let you know exactly how clean your air is).

Manual operation is fast and efficient as well thanks to the free Airmega app for iOS or Android. No need for a separate remote control!

The combination of the large coverage area, three-stage filtration, numerous options for either manual or automatic operation, and the five-year limited warranty makes the Airmega 400 our pick for the best air purifier for pets in large spaces.


  • 1,560 sq. ft. coverage area
  • Convenient Max2 combination filter
  • Filter change indicators
  • Remote control via smartphone app
  • SmartMode automatic operation


  • Max2 filters expensive to replace
  • Large size limits where it can be installed

Considerations Before Buying a Purifier

When you are shopping for the best air purifier for pet dander there are many considerations that should factor into your buying decision. Many of them may not be immediately obvious to you, however.

Let’s take a few minutes to review these items so you can make the best, most informed buying decision.

Coverage Area

Some are big…some are small. Not talking about your pets, though!

I’m talking about the size of the room or area that you are looking to place your air purifier in. Just as rooms vary in size, so do the purifiers themselves.

The size of an area that an air purifier is designed to effectively clean is called the coverage area. You’ll see “coverage area” as one of the main specifications for purifiers, and with good reason – you don’t want to pay extra for a unit that has too much capacity, nor do you want to have one that is too small for the area you want to use it in.

So, how can you figure out what coverage area you need? You can figure it out easily by taking a few simple measurements and grabbing a handy calculator.

Start off by measuring the length of the room (L). Then do the width (W). All you do then is multiply the two numbers to get the area of the room. That number will tell you how much capacity you need your air purifier to have.

For example, let’s take a look at a small bedroom. Let’s say that the length measured 12 feet, and the width was 10 feet. 12 x 10 = 120.

From this, you’ll know that you will need an air purifier with a coverage area greater than 120 square feet. I say “greater” because it is always better to go a little over than a little under.

But don’t go TOO far over. Higher capacity units tend to be more expensive, so does it make sense to get a unit rated for 1,500 square feet when all you need is 120? Nope – it sure doesn’t.

Filtration Type

We’ve already discussed the benefits of using a good quality multi-stage unit for removing pet-related contaminants from the air, so you should have a good idea of what to look for.

The issue is that not all air purifiers are created and designed the same.

Some have three stages, some have more…and some may have less. The bottom line is that they are different from model to model. There are units out there that are “general purpose”, while others are certainly geared toward pets or mold/mildew removal.

It is always a good idea to take your time and do your homework so you end up buying the unit that best fits your needs.

Filtration Life

Most air purifiers have “consumable” filter elements in them. That is similar to the brakes and tires on your car. They will get consumed as they are used and eventually will need to be replaced.

The actual time between filter changes depends on a few factors, with the most important ones being:

  • Type of filter element (HEPA or carbon, etc.)
  • Amount of use

Most manufacturers will have recommended filter change intervals based on what they call “regular use”. That may be different from person to person though. Someone that uses their air purifier more often may have to change their filters more often.

As a general rule of thumb, a HEPA filter is typically changed out every two to three years. A replaceable filter with an activated carbon filter element can last anywhere from three to five years.

There are also some filter designs that you do not need to replace, saving you money in the long run. Ionic systems need to be simply cleaned, and there actually are some HEPA filters that can be washed out and air-dried as well.

Particle Removal Capacity

You may see “particle removal capacity” mentioned as a specification. This is usually a description of the type of filtration technology that is primarily used in the unit.

Remember the HEPA specs? That is removal of 99.7% of particles that are as small as 0.3 µ, which is extremely efficient and may be more than adequate for most pet-related usage. This can be confusing, especially when you have smoke issues in your home.

Another specification you may see (but not as common as HEPA) is PM2.5. PM2.5 isn’t as exacting as HEPA as it relates to particles that are 2.5 µ in size. It’s still an effective and usable option; however, we would choose a HEPA unit over a PM2.5 for most purposes.

Clean Air Delivery Rate (CADR)

CADR is a good way to measure the overall capacity of an air purifier.

It is a way to describe how much air can be processed through a unit, given in terms of cubic feet per minute (CFM). Higher CADR ratings are better because that means more air that is being cleaned over a set period of time.

One thing to keep in mind is that the CADR rating for a unit can change based on the types of airborne hazards it is being used for. If larger particles (such as pet hair or dust) is your main concern, then don’t confuse that rating with the one for smoke.

Portability & Ease of Use

Air purifiers that are designed for home use are designed for convenience. None of the models we have reviewed are hard-installed, and moving them is a simple as picking them up and moving them to another area. There are units that are permanently

The electrical connections are made with a simple plug-in to a standard wall outlet, so we would recommend unplugging the thing first before you try to move it from place to place.

As far as ease of use is concerned, these units don’t require an advanced degree to figure out how to operate them. Most are as simple as plugging them in and turning them on. As the feature sets increases from unit to unit, some may have fan speed switches while more expensive units will automatically monitor air quality and adjust the fan as needed.

Can’t really get much easier than that!

Noise Levels

Air purifiers are typically not very loud, especially when you compare them to a box fan or an air conditioner. That being said, they do emit a small amount of noise. How much sound a unit produces is determined by the design and size of the fan.

Noise and sound levels are measured in decibels (or dB). Louder sounds are equal to larger numbers. Most air purifiers sit in the mid-50’s dB range, making them softer than normal conversation (see the table below).

So, no – using one won’t make it seem like you have a jet taking off in your living room! Actually, some folks like a little bit of background noise; it even helps them to sleep a little better.

Decibel (dB) Level Sound Equivalent
0 dB Normal hearing threshold
30 dB Soft talking/whispering
60 dB Normal conversation
90 dB Lawnmower engine
140 dB Jet airplane

Energy Efficiency

An air purifier may be one of the most energy-efficient appliances that you can have in your home.

Other than the electronics needed for controlling the unit, pretty much the only other thing that would need power is the fan itself. Those are typically pretty small and tend to not draw a lot of electrical current (and, therefore, not use much electricity).

To be fair, larger units that are designed to accommodate a larger coverage area may use a little more power, simply because they will have bigger fans. The difference may not be all that noticeable though.


As with any other commercial product, air purifiers typically come with some level of warranty direct from the manufacturer. These warranties typically cover defects in materials and workmanship, with the length of time ranging from a year to lifetime (for some models). It goes without saying, but the longer of a warranty you can get, the better.

Keep in mind – the “consumable” filter elements are not covered. They are intended to be replaced at your cost.

On top of that, the store you buy it from may offer an extended coverage plan as well for an extra cost. You don’t have to buy these plans – don’t get confused and think that is your only way to cover your purchase! To be fair, they usually do offer a coverage level up and above what the manufacturer offers, so that may be a consideration for you.

Air Purification Technologies

There are several types of filtration technologies, each with their own strengths and weaknesses. Let’s take a look at the ones that are most likely to be found in a good quality air purifier:


If you have ever looked at any sort of air filtration products before – even the filters that you may be using on your furnace – you most likely have come across the term “HEPA”.

High-Efficiency Particulate Air (HEPA) is a specification that is standard throughout the industry. It relates the size and amount of airborne particles that the filter can effectively trap.

The main reason why the use of HEPA filters is so prevalent is how well it works. In order to be considered a HEPA filter, it has to be able to trap particles as small as 0.3 microns (µ). A micron is 1/1000 of a millimeter, so 0.3 µ is pretty small. Just for reference, a human hair is close to 75 µ thick!

On top of that, the specification states that a filter classified as “HEPA” must capture at least 99.7% of particles of that size. Pretty impressive!


Believe it or not, even a filter that is rated for HEPA efficiency may not get all of the airborne contaminants out of the air in your home. This is one reason why most air purifiers on the market are what are called “multi-stage” Multi-stage units combine several technologies into one so you can get the benefits that each has to offer.

HEPA is a very efficient technology, but it isn’t necessarily the best choice for removing gases, volatile organic compounds (VOC’s), or odors. One of the best options for these purposes is the use of a filter with an activated carbon element.

“Activation” is a process where the structure of carbon is changed, either by temperature (heat) or a chemical process. This changes the absorption qualities that carbon naturally has and makes it much more efficient.


While not the most common technology, you may come across ultra-violet (UV) radiation as an option within a multi-stage air purifier.

It is effective because it uses UV-C (a type of UV wavelength) to actually destroy particles instead of just trapping them as a mechanical filter (such as HEPA) would.

Sounds great, right? Then why wouldn’t you just use UV all the time?

While it’s true that is works, UV-C radiation can actually be pretty harmful to humans. UV-C isn’t the same “UV” that you hear about when you are getting a suntan. The Earth’s atmosphere filters out almost all of the UV-C that comes to us from the sun.

So yes – some select purifiers use it in an efficient manner, but many manufacturers choose not to.


Ionic methods for particle trapping is pretty “techie”.

Instead of going through a filter with super-duper tiny holes in it, an ionic filter uses some good old physics to work. You thought you were out of school, right?

In an ionic “filter”, metal plates have a negative electronic charge applied to them. This creates an attraction effect where particles are drawn to (and collected on) the plates themselves.

“Filter” really isn’t the right term, even though the end result is relatively the same. One benefit of an ionic system is that the filters typically do not have to be replaced. All you have to do is clean them every now and then to get them back like new. How often depends on how heavy your use may be.


And you thought ionic technology was like advanced science…

Explaining how ozone may be a good air filtration method comes straight out your old high school chemistry book!

Take an atom of oxygen and add an extra molecule to it. You then get ozone. Ozone has particle-destroying properties just like UV-C does. But, similar to UV-C, overexposure can create a multitude of health problems, including chest and lung irritation, increased coughing, and chest pain.

Effective…but it may not be the best choice for inside your home. If you do choose to use an air purifier that uses ozone, please make sure to use it properly only as the manufacturer has intended.

Health Issues Caused by Pets

While it’s certainly true that owning a pet can have positive effects, there is an unfortunate flip side to the coin.

Pets can trigger several types of diseases in humans, many of them being bacterial in nature. While some of the breathing-related issues may not be as serious as a case of rabies, they are still troublesome. Some allergic reactions to certain types of pets can be very disruptive to everyday life.

While an air purifier may help to minimize airborne bacteria, they can be very effective with trapping the pet dander that can cause. Referring again to The American Lung Association:

People with allergies may experience upper and lower respiratory tract symptoms including congestion, sneezing, runny nose, chest tightness, and wheezing. Other symptoms are itching, watery eyes, and eczema or rashes.

And…bad news for cat lovers. People may be twice as allergic to them than dogs…

What Else Can You Do to Reduce Pet Allergens?

Using an air purifier when pets are present is a great supplemental choice to reduce the pet dander and allergens in the air. It’s important to understand that even the best air purifier for pets will not completely eliminate all of the hazards.

And let’s be honest – the likelihood that you are going to remove your beloved pet from your home are pretty slim, right?

As part of a total strategy there are several other things that you can do as well:

    • Bathe your pets regularly – weekly is preferred
    • Regular grooming helps to avoid allergen and dander buildup
    • Restrict your pet’s access to certain rooms, such as your bedroom
    • Use covers on bedding
    • A more extreme solution is to take allergy shots or over-the-counter allergy medications
    • If you have a cat, keep the litter box cleaned
    • Keep pets off of your furniture
    • Keep your carpets vacuumed

Tips When Using Air Purifiers With Pets

When using an air purifier, you shouldn’t expect that all you need to do is plug it in, turn it on, and you’ll magically have no more issues with pet allergies. There are many strategies that you should take in order to make sure your use is as efficient as possible.

Regular Filter Changes

Many models have indicators that will let you know when it’s time to change or clean the filter elements – that’s the easy part. But…you need to actually do it!

I think that everybody is guilty of that kind of thing in one sense or another. Who here hasn’t let the filter change light for the water on their refrigerator stay on for much, much longer than it should have?

Or…who hasn’t changed the oil in their car when the time is right?

Guilty as charged, your honor…

Here’s the thing – manufacturers don’t build in indicators or give you time interval guidelines on when to change a filter just so they can make more money. I mean…sure, they DO make money, but keeping your filters fresh will let your purifier run at the best capability it can.

Automatic Mode

Automatic modes are also a great thing to take advantage of. More than likely you may have paid a little more to get features like that, so why not use them?

Some units actually monitor the air quality and will adjust its operation without any action on your part. It is just about as close to “trouble-free” as you can get.

Placement in the Room

Be mindful of where you plan to put the unit. It should be placed in an area where the maximum amount of airflow can be achieved. Hiding it behind a chair or putting it too close to a wall can limit its overall effectiveness, and essentially lower the units CADR capacity.

Windows and Doors

This one really is based on common sense. If you have outside air – even air from other areas within your house – that can get into the space you are trying to control, then you need to keep the doors and windows shut as much as possible.

Capacity Matters

Remember when we talked about coverage area? Don’t get a unit that is undersized for your room, because it’ll struggle to keep up and clean the air as efficiently as it should.

People Also Ask (FAQs)

What is anti-bacterial coating and is it necessary?

Anti-bacterial coatings can be a great feature. Dander is made up of organic material, so think about this for a second – if you have a filter that is trapping a bunch of that nastiness, then wouldn’t you think that, if it sets there over time, that bacteria could start to reproduce?

The coating will help to minimize bacterial growth and keep it from getting blown back into the room.

Will air purifiers help clean the air of pet-related problems?

Will they help? Absolutely! Using a HEPA filter (common in most units) may be one of the most effective things you can do.

Will it completely eliminate any issues and solve all of your pet-related problems? Most likely not. No solution is 100% effective and perfect. The recommendation is to use an air purifier as part of an overall strategy to minimize pet allergen exposure as much as possible.

What are the main differences between cheap and expensive brands?

Less expensive units tend to have smaller feature sets and capacity levels that may not stand up to larger areas. There also may be a quality factor as well. Let’s face it – sometimes you really do get what you pay for…

Models and the higher end of the price range may use better components, have better build quality, and all of the bells and whistles like automatic modes and filter change indicators.

Where is a good place to buy quality air purifiers?

Buying an air purifier online or in a brick-and-mortar store really isn’t any different from any other purchase that you may make.

Online purchases offer convenience and the ability to read reviews, but you typically will have to wait a few days unless you pay extra for next-day shipping.

Buying in a store gives you the option of having the unit right away, and there may be a store associate that can help answer any questions that you have.

Price is always a factor here too – you may find something cheaper online, but factoring in the shipping costs can make it ultimately more expensive.

Are air purifiers safe and healthy machines to run in my home?

We would not anticipate there being any issues with running an air purifier in your home. Even in the cases where you may decide to buy a unit that has a filtration method that could be hazardous, the manufacturers typically design their products with enough safety features to give you peace of mind.

Are these systems easy to install?

You really can’t get much easier, for the most part. Find a good spot to put it that will maximize the airflow that’s close to a wall outlet (extension cords can cause a tripping hazard – safety first). Plug that bad boy in and you’re good to go!

Are these systems easy to maintain?

Most certainly – maintenance is pretty much as simple as keeping the filters changed. They typically aren’t user-serviceable as far as the electronics or working components (such as the fan motor) are concerned – that’s just another reason to look for a unit that meets your needs and has the best warranty.

How often should you expect to change filters, and are they expensive and easy to replace?

We have noted a few times when it’s the right time to change the filters – either when your filter change indicator (if your unit has one) goes off or when the time interval recommended by the manufacturer comes due.

Cost-wise it can be all over the map. Simple single element filters may not cost that much, but there are some models that integrate multiple stages into one filter housing (such as possibly a HEPA and carbon element). Those types of “multi-filters” may tend to put a little bigger burden on your operating costs over time. It’s certainly worth considering, especially if you are comparing two units that are almost the same – how much will it cost to keep in running?

As far as ease of changing, most simply slide in and out with no tools or advanced physics degrees required.


Making any type of purchase can be a daunting task, especially when there are so many options available from you to choose from. Air purifiers are no different! On top of that, you have to make sure that the units you are looking at are the ones best suited for your purpose. An air purifier that is best for mold and mildew may not fit in good for pet hazard removal.

Taking a look at everything we have discussed, we think you’ll see that the Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier has earned the distinction of being our top choice as the overall best air purifier for pets.

Now – go plug that new air purifier in and give your pet all of the attention that they deserve!
