Buying Guide: How To Choose The Correct Air Purifier To Remove Pet Odor And Allergens In Your Home

You’ll be able to choose the best air purifier to buy among the various options available with the help of this buying guide. Here are the essential criteria to look out for: 


Room Size To Purify

Determining how much space your air purifier can purify is the number one priority. Small air purifiers won’t be effective in large rooms and vice versa. This limitation primarily has to do with the device’s air changes per hour. 

best air purifier for litter box smell
  • Save

Generally, a small air purifier can purify the air in a 350-square-foot space about eight times per hour. For a 690-700 square feet room, it purifies just four times per hour. 

You should get the correct measurement of your room before purchasing the best air purifier for cat litter odor. It’s ideal to buy a larger air purifier than you think you’ll need to be on the safe side. 


Filtering Of Heavy Or Light Pollutants In The Home

It would be best to have one effective air cleaner for the area to eliminate cat litter odor, urine smell, dust, and litter box smell. Therefore, the product chosen must be capable of dealing with such heavy pollutants.

As you can see from the list above, some air purifiers are better at capturing litter dust than odor and vice versa. If litter odor and box smell is your main issue, a purifier with activated carbon is the best option to consider.


The Air Purifier Has A CADR Rating 

You can tell how well an air purifier filters pollutants in a room by looking at its clean air delivery rate (CADR) label. 

A CADR of 300, for instance, means the air purifier can provide 300 cubic feet of clean air per minute to reduce pollutants. The CADR of air purifiers varies depending on the type of pollutants it targets. 

Air purifiers with the highest CADR numbers remove the most pollutants and can purify larger rooms. According to EPA (Environmental Protection Agency), these are the minimum CADR ratings per room size: 

  • 100 sq ft – 60 cubic ft a minute 
  • 200 sq ft – 130 cubic ft per minute 
  • 300 sq ft – 195 cubic ft a minute 
  • 400 sq ft – 260 cubic ft per minute 
  • 500 sq ft – 325 cubic ft a minute 
  • 600 sq ft – 390 cubic ft per minute 

If your primary target is to remove litter dust or strong cat odors, you should consider the highest CADR ratings. However, not all air purifiers come with CADR labels.  

While CADR is an excellent factor to consider, it doesn’t mean products without the rating aren’t reliable. 


Filters Availability

Most of the air purifiers in the above list feature a mechanical filtration process. The filters trap dust and other pollutants as they pass through. Usually, they come with two filters—a pre-filter for large contaminants and a primary filter for smaller pollutants.

  • Save

What is most important is the primary filter. It’s ideal to opt for a device that uses a HEPA filter. HEPA filters capture 99.97 percent of pollutants, including large and tiny ones. 

Some devices claim to have HEPA-type filters yet don’t truly meet HEPA filtering standards. For this reason, it’s difficult to conclude that HEPA-type filters will always perform best. To be on the safe side, products with “True HEPA” filters are ideal. 

You have to look for additional filters with odor compounds, activated carbon, and VOCs for trapping cat litter odor. These extra filters often require frequent replacement to maintain effectiveness. 

There are air purifiers that filter using ionizers or UV light. While they can be effective, the disadvantage is that they may produce ozone, a lung irritant that could exacerbate any breathing issues. 

If you opt for air purifiers with ionizers, go for the ones that you can deactivate. That way, they don’t stay on all the time. If you still need more information about how a filter works, see the video below.


Noise Level Of An Air Purifier

Fans within air purifiers draw air through filters. While some devices come with whisper-quiet fans, others can be very loud. Noise is a discomfort to you and also your pet.

  • Save

The regular air purifier makes less noise even at higher speeds. Most of the devices we provided here have medium to almost silent noise levels, so they are quiet. However, you can check the device’s specs for the noise level; consider those with a noise level 25db and below if you want an almost silent device. 


Portability Of The Air Purifier

Most of the air purifiers I listed are not large and are light in weight. The advantage is that you can easily carry them from room to room, anywhere you need to remove cat litter odor.

  • Save

However, an air purifier’s size relates to the size of the area it can successfully purify. You’ll need to compromise on size and portability if you want one air purifier to cover your entire house. 

If you have a large room, you can go for a larger and relatively heavier air purifier and place it in a permanent spot. Better yet, go for one with casters, so moving isn’t too tricky. 


Maintenance Cost Of The Air Purifier

If you’re on a budget, you need to consider the price when purchasing the best air purifier for litter box smell. Price here doesn’t involve just buying the product but also maintenance. To start with, you’ll always need to replace the filters when due. 

You can wash and reuse some pre-filters. HEPA filters, on the other hand, are disposable and must be replaced unless the permanent ones. Replacement filter costs vary for every air purifier. Some are cheap and won’t last very long; others are pricey and long-lasting. 

Calculate the annual maintenance costs of your chosen product and compare them to other air purifiers before making your purchase. 


Energy Usage Of the Device 

To get the most out of your chosen air purifier, you have to use it constantly. As a result, you must consider electricity expenses. Generally, air purifiers that use less energy are for smaller rooms.

  • Save

Conversely, large-room air purifiers with faster fan speeds consume more energy. The former may not even be noticeable on your electricity bill, whereas the latter can make a noticeable impact. 

I listed some Energy Star-certified air purifiers in this article. Such products are reliable when it comes to energy saving. 



Some air purifiers include extras like filter-replacement signal, programmable timer, RC unit, nightlight, and dimming & display shut-off options. Some come with intelligent features like digital assistants and mobile apps.

These extra features will make using an air purifier device more manageable and more convenient. However, you have to watch out for price as devices with extras are usually more expensive. 



Q: How do I keep the litter box from smelling in my house?

A: You can try keeping the box in a well-ventilated area, scoop daily or more, and replace it frequently. 


Q: Do air purifiers remove odors?

A: Yes, air purifiers remove odors by trapping microparticles that create unpleasant smells. Without an air purifier, the particles can remain in the air for a long time, causing discomfort to you and your pet.


Q: How long for an air purifier to clean a room?

A: This depends on the room size, purifying mechanism, and operating power. It’s different for every product, and you can check the specs to confirm. 


Final Verdict

Purchasing the right product should be easier at this point. You can pick from any of the reviewed products and follow the buying guide.
