Do Air Purifiers Help With Dog, Cat & Pet Smells?

by Josh M

You love your pets, but their smell can be overwhelming at times. It’s no secret that pet odors can be potent. It’s hard to keep your house clean when offensive smells are wafting through the air.

Air purifiers are a great way to eliminate olfactory problems and keep your home smelling fresh. By removing odors at their source, air purifiers make it easier to live more comfortably.

Air purifiers function by removing airborne contaminants from the air. These contaminants include dust, pollen, mold spores, and other allergens.

Many air purifiers also feature activated carbon filters. These filters remove smoke, chemicals, and other VOCs (Volatile Organic Compounds).

An activated carbon filter is the best filter for removing pet odors from the air. These filters contain charcoal that has been treated with gas or steam to open up its pores. This feature allows the filters to absorb more contaminants from the air.

So, do air purifiers help with pet smells? The answer is yes; they can. Activated carbon filters capture microscopic particles, including pet odors.

HEPA filters work well in combination with activated carbon filters. HEPA stands for High-Efficiency Particulate Air. These filters remove 99.97% of airborne particles of 0.3 microns in size or larger.

While HEPA filters do not trap odor-causing molecules as activated carbon filters do, they capture a large amount of pet dander, which can contribute to pet odors.

The best choice is a three-stage filter that includes a standard filter to capture hair, an activated carbon filter, and a HEPA filter.

Why Do Dogs and Cats Have Strong Odors?

One of the most common causes is a lack of grooming. If your pet isn’t being regularly brushed and washed, their fur can start to harbor dirt and bacteria, leading to an unpleasant smell.

Another factor that can influence problem odors is a pet’s diet. Pets that eat cheap processed foods or foods with intense flavors and smells can often have bad breath or body odor.

Dental issues can also cause bad breath. If you suspect your pet’s bad breath might be due to dental problems, it’s always best to consult your veterinarian. The smell can transfer to your pet’s fur if not regularly groomed.

Skin infections can also cause your pet to start smelling bad. If you notice your pet’s fur is greasy or oily, or they seem to be scratching, they may have a skin condition requiring treatment.

So why do air purifiers help with these smells? Air purifiers work by trapping these odor-causing particles and removing them from the air. This process helps to lower the overall level of odor in the environment.

Why is it difficult to stop? While the smell of pet waste can be unpleasant, it is not always easy to stop the smell from occurring initially. This is because pets often have accidents in areas that are difficult to reach, such as under furniture or in corners.

Once pets have soiled an area, they may gravitate to it because of the odor and have a repeat performance.

If you’re dealing with pet smells, one of the best things you can do is run your air purifier continuously for up to a week. This will help remove the smell from the air, making your home a more pleasant place.

Be sure to place the purifier in the room where the pet spends the most time. This placement will help target the odor source and get rid of it quickly.

Where Should the Purifier Be Placed?

How Long Should You Run the Purifier Per Day/Week?
