Breathing in clean air plays a crucial part in having a healthy body and life. However, many times this factor is difficult to control without the help of a special device made for cleaning air.

Air purifiers do exactly that – capturing and removing harmful particles from the air you breathe. These can come in the form of dust, pet dander, pollen, smoke, and many more contaminants.

As so much variation exists when it comes to air purifiers, we took it upon ourselves to research in-depth to bring you the best models on the market. Alencorp is a brand that produces some of the best out there, and if you want high quality, they’re the way to go.

Why Choose Alencorp Air Purifier Brand?

Filtration Technology

Alencorp uses a 3-stage filtration system, where you get to choose between various HEPA air filters. However, before they get to the HEPA, the pollutants first reach a pre-filter.

This is to add to the efficiency of the filtration system as it catches larger particles while also extending your HEPA filter’s lifespan, which will also save you money!

True HEPA Filter Customization

While many competitor brands offer just 1 filter option, Alen offers 4: Each has its own specific purpose for you to help select a filtration set up perfect for your body and home.

  • HEPA-Pure
    This is the default HEPA filter you’ll find with many models, capable of catching up to 99% of pollutants as small as 0.3 microns, like dust and pollen.
  • HEPA-Fresh
    This takes things up a notch, as it also comes with an activated carbon filter that removes unwanted odors like light smokiness, cat box, and so on. If you’re particularly sensitive to VOCs, this is the one for you.
  • HEPA-Silver
    This costs a bit more, but it comes with antimicrobial Silver-Ion threads, which help eliminate the growth of mold and bacteria.
  • HEPA-OdorCell
    Finally, we have the boss level of HEPA filters, which comes with the brand’s signature Molecular Conversion Powder, which obliterates odors on a molecular level!

Smart Sensor

To help provide you with the cleanest air possible, the Alen purifiers typically come with various smart technologies to improve the user experience. One of these is the Smart Sensor. This sensor detects particles in the air of the room it’s located in, evaluating the quality of the air and change the fan speed depending on this data.

Smart Filter Timer

A timer may not be necessary for many, but it definitely makes for a more user-friendly experience. This timer will alert you when your filter is nearing the end of its lifespan, so you know when it needs changing out.

LED Filter Life Indicator

Here, you’ll see a few different lights: green, yellow, and red. Green is “good,” while yellow lets you know it’s coming close to replacement time, and red means it absolutely needs replacing now.

Pink Noise Frequency

Alen ensures noise is kept to a minimum. Even at its highest setting, it’s quieter than the majority of competitor options on the market. You’ll never have to worry about it negatively affecting your sleep quality, as they produce pink noise frequencies.

Pink noise frequencies are known to work as a sleep aid, which can alter brain waves in such a way that calms us and makes it easier to fall into a deep sleep.

Energy Star Certification

To make the most of our purifier, it should be run the entire day and night. This means energy consumption, though with Energy Star ratings, these models do their best to conserve energy.

Minimalistic Design

We were hard-pressed to find an air purifier that came close to sporting the beautiful looks Alen’s do. The minimalistic design looks good with any kind of existing décor you may have.

Alen Forever Guarantee

With the Alen Forever Guarantee, you’re covered for 5 years. Not only that, but you can qualify for a lifetime warranty by registering your product and enrolling in a filter subscription.

Excellent Customer Service

Alen’s products are wonderful on their own, but it’s their above-and-beyond approach to customer service that really seals the deal for consumers. They also offer discounts and coupons on their own website so feel free to click the products below and check out the ‘first-time buyer’ promotions on offer.

They provide ample content on their site to help their customers and are easy to reach by telephone and email. Shipping is free and fast, and even guarantee same-day shipment if you order before 3 PM!

If you are sensitive or allergic to pollen, dander, pet fur, dust mites, etc. then you’ll make good use of this model.

Cleaning up to 3 times faster than competitor models, it’s incredibly efficient and leaves behind clean, fresh air. The CADR rating is a bit low for this space, but we had no complaints. Even during heavy pollen seasons, we were left unaffected.

As previously mentioned, it does come with pre-filter to help capture larger particles while lengthening the life of your True HEPA filter. Moreover, you get an ozone-free ionizer, which further with particle-catching efficiency. You can also choose to add on a HEPA Silver, Fresh Plus, and OdorCell, though they do not come included by default.

If you found the previous model interesting, but have a smaller space, the Alen BreatheSmart FLEX fits right in. Look through any Alen BreatheSmart Flex air purifier review, and you’ll find it’s perfect for individual bedrooms, nurseries, smaller offices, etc.

Weighing just 15 pounds, you can easily move it within your home and don’t have to dread lugging it from room-to-room.

Just like with the others, you can choose front paneling to suit your tastes and décor. From White, Electric Blue, or Brushed Stainless to Espresso or Oak – the choice is all yours.

Cleaning up to 700 square foot spaces every 30 minutes, it’s twice as fast as competitor models when on the highest speed setting. At full speed, it’s a bit louder than the Classic (55 dB) though still quiet enough to fall asleep with. For children’s rooms and nurseries, it couldn’t be better. Sleep Mode comes with a Lights Out mode, too, so you’re not distracted by LEDs.

The True HEPA filter captures up to 99.7% of airborne particles down to 0.3 microns and lasts up to 12 months. In addition, it can kill mold spores and bacteria with its antimicrobial compound. While it’s great for year-round use, it is particularly handy during cold and flu season.

Consuming just 50 watts on Turbo speed, we found that it actually saved us money in electrical bills!

  • Great for small room coverage
  • Custom color options
  • Very quiet operation
  • Kills germs and mold
  • Low energy consumption
  • Compact and portable

The Alen BreatheSmart FIT50 is the brand’s “#1 recommended purifier for wildfire zones, which can help create an EPA-recommended clean room for refuge from toxic smoke.”

However, even if you’re just looking for everyday usage, it packs more than enough power. It may be compact, but it’s serious about removing harmful particles in the air you breathe.

This model is perfect for spaces up to 900 square feet and comes with 8 different color options. Each is absolutely stunning so you can put it anywhere in the home.

A True HEPA filter is great for those who suffer from allergies or are bothered by household odors, fur, etc. We noticed that even just the first time turning it on, we felt less congested and were breathing with less effort.

The air quality sensor gauges the particles currently in the air. The power button changes colors according to the air quality. Blue means “excellent,” orange is “fair,” and red is “poor.” Switch it to Auto Mode, and it will automatically change the fan speed depending on the quality status. Four fan speeds are optimized to bring you perfectly purified air, no matter the situation.

Even if it’s on Turbo mode (the highest), you can rest easy with their advanced WhisperMax technology. This feature produces pink noise frequencies to help you fall asleep easier, feeling well-rested each morning.

CADR350

Making our way towards the end of our list, we bring you the Alen BreatheSmart 75i air purifier. If your top priority is a purifier that can take on large spaces, we can’t recommend this one enough. Thanks to the inclusion of activated carbon filtration, you no longer benefit from just cleaner air, but fresher smelling air.

Capable of plowing through 1,300 square feet in just 30 minutes, it’s perfect for even your widest open spaces or rooms. You get your choice of 5 different fan speeds and a 2-hour, 4-hour, or 5-hour timer.

The smart sensor will detect the number of airborne particles and auto-adjust the fan speed according to this. You’ll be able to see the LED color display as well, just so you’re aware.

Even at its highest speeds, you will hardly notice any noise. Developed by a former NASA engineer, the whisper-soft volume will never distract you from your work or studies. Consuming 45 watts of energy, this model uses the least out of all BreatheSmart air purifiers, currently.

While it’s slightly more expensive than the others, it’s worth it when you combine all of this with the extended HEPA filter lifespan. While alternative filters last around 9 to 12 months, this one lasted up to 15! In the end, this Alen HEPA air purifier ends up saving you money!

Pros

  • Great for large areas
  • Custom color options
  • Helps remove VOCs, foul odors
  • Very long filter lifespan

5. Alen BreatheSmart 45i

Best for Allergies
Coverage Area800 sq ft
Filtration Type4
Filtration Life9 – 12 months
Noise LevelMax 55 dBa
CADR245

While any of the models on our guide help with allergies, if that’s your main priority, then the Alen BreatheSmart 45i should be at the top of your list. From irritated eyes from pet dander to full-blown allergic reactions, the 45i can help.

It’s affordable when compared not only to other Alen models but competitor options all across the market currently. However, quality or performance stay top-notch.

Appearance is slim and sleek, though it does come with notably fewer color options than the others we’ve covered. You get a classic White, White Marble, Espresso, Weathered Gray, and more – all of which look sophisticated and trendy.

Despite being so compact, it cleans up to 800 square feet every 30 minutes, making it ideal for a bedroom, living room, kitchen, and more.

Not only does the PLUS filter capture bacteria and mold spores, but it also eliminates dust, dander, and pet allergens. During flu season, you’ll be happy to have this model, as it can significantly reduce the chance of these viruses taking up residence in your home.

The air quality light and sensor lets you know the kind of air quality your home is at currently. When used with Auto Mode, it adjusts fan speed on its own, depending on the level of contamination. It is very quiet throughout each fan speed; however, it’s slightly noisier than others on our guide.

Pros

  • Great for bedrooms
  • Compact and lightweight
  • Great for allergy sufferers/pet households
  • Beautiful design

Cons

  • Relatively low CADR rating for room size

Who Makes Alencorp Air Purifiers

Based out of Austin, Texas, this company is one of the top when it comes to air purifiers. They gained their sparkling reputation through consistent quality and incredible customer service.

Instead of offering cookie-cutter options, they have customizable solutions that fit your home, physical requirements, and design preferences. Their smart solutions are appealing to those who aren’t very tech-savvy but still want real quality and performance.

Started by founder, Warburg Lee, who suffered from allergies, he recognized from his own experiences that there was a severe lack of effective air purifiers out there. Those that were, were incredibly noisy and not ideal for enjoying home life. Through dedication and precise engineering, Alen has become an industry leader with very few real competitors.

The Alencorp Air Purifier Range Explained

  • Small Spaces:
    If you’re looking for a model to clean air in small spaces, check out the Alen BreatheSmart FLEX. The FLEX is great if you have a small room that needs purifying, such as a nook, basement or office.
  • Medium Spaces:
    The BreatheSmart 45i and FIT50 are your go-to’s for medium spaces like bedrooms, living rooms, kitchens, and nurseries. They work with most areas, so if you doubt which size to get, either of these will likely be realistic solutions.
  • Large Spaces:
    If you need heavy-duty air purifying, check out the 75i or the Classic. Either of these can take on over 1,000 square foot spaces and are made for open layouts and big rooms.
  • Allergies:
    If you need something to help minimize allergy suffering, look at the BreatheSmart 45i. The 45i is very affordable as well, so if you’re on a budget, look here. The 75i is another excellent solution for allergy sufferers or those sensitive to VOCs; however, it’s significantly more expensive.
  • Pet Odors:
    Again, the 75i is a top performer in this category and essentially eliminates all foul odors and bacteria. The FIT50 is another one of our favorites for killing pet and other odors such as smoke. In fact, it’s EPA-rated for precisely this.

Comparing Alen with Similar Air Purifier Brands

Alen vs. RabbitAir

Alen is significantly more powerful and capable of covering almost twice the area that RabbitAir can. We also found RabbitAir to be notably noisier, with fewer filter options, a shorter warranty, and no custom color options. On top of that, it was much less energy efficient, which will end up costing you more money.

Alen vs. Dyson

Dyson may be more affordable in most cases, but that’s only when it comes to upfront costs. Their average warranty lasts 2 years, and after that time, you may have to spend more for another air purifier unit. In contrast, Alen offers a lifetime warranty, so you never have to worry about buying another.

In addition, room coverage with Dyson is even less than with RabbitAir. There’s only 1 filter option, although you do occasionally get a couple of custom color panel options.
