Are you tired of your home smelling like litter? I can relate to that, especially as a cat parent living in a small space, but I found the definitive solution with air purifiers.
Air purifiers are safe for cats, and can definitely help us with that and more!
These devices can solve a lot of issues, of which we may even not be aware of. For instance, if you know someone who’s allergic to cats, they might be no more after getting an air purifier, as it gets rid of many invisible allergens.
Before the recommendations, let’s see what to look for in an air purifier for our purpose.

It’s important to clarify what we looked for and prioritized when selecting them. There are many air purifiers out there, but you’re here because you want the best one for a specific need.
If you want to get rid of cat litter odor and harmful allergens, these are what the ideal air purifier should have:
- HEPA Filter: HEPA stands for “high-efficiency particulate air”. It’s a popular type of filter that serves as a captor of small particles such as dust, dander, and bacteria. As most air pollutants are removed thanks to this filter, air quality can improve significantly if your air purifier has it. It’s quite standard, so it won’t be hard to find air purifiers with a HEPA filter.
- Activated Carbon Filter: This filter is essential for our purposes. An activated carbon filter usually acts as the last barrier in the set of filters an air purifier features, and functions as the eradicator of odors and volatile organic compounds (VOCs) such as those that originate from cat litter. By trapping those molecules, potent smells are significantly reduced.
- Noise Level: Air purifiers run for long hours, so a low noise level while turned on tends to be a desired feature for many buyers. Quick tip: You can read any air purifier’s features and look out for the noise level in decibels, which will help you compare.
- Room Coverage: Air purifiers come in all shapes and sizes. Some are intended to be light and portable, while others are bigger and meant to be kept in the same room for the most part. Consider in which room you’ll be placing the air purifier, this will be ideally in the same room as your cat’s litter box.
For maximum odor reduction: Consider changing to Tofu cat litter.

How Cat Litter Affects Indoor Air Quality
Here are some of the most important issues cat litter presents that affect air quality:
- Odor Control: As you probably know, cat litter doesn’t smell like flowers. The odor of urine and feces that comes from the litter box can clog your nose (if you don’t scoop it daily, or more if you have more than one cat like me). Without proper ventilation or an air purifier, these odors tend to linger around your home.
- Dust and Particles: This is particularly common with clay-based cat litter. These litters come and/or generate dust that gets released when your cat uses the litter box and it can be harmful to you and your cat, as it can be easily inhaled. Tofu cat litter is dust-free, and it’s one of the main reasons why we recommend it over other clumping cat litter options such as clay.
- Ammonia Levels: Cat urine contains a highly irritating gas known as ammonia, which can build up in the litter box over time and float around it. High levels of this gas can irritate your eyes, nose, and throat and cause respiratory issues. If you suffer from any of this or want to prevent it, an air purifier can help deal with it.
- Bacterial Growth: The litter box can easily become a host of bacteria and many other microorganisms. When your cat uses the litter box, you scoop it or in any way these get disturbed, the bacteria can become airborne and directly impact air quality and odor levels. This is why the HEPA filter (which we will cover in a second) is so important in air purifiers.
- Allergen Control: Like humans and other pets, cats can shed dander. These are microscopic-sized skin cells known for being a common allergen. An air purifier would help in reducing the levels of these allergens, and its effect is bigger when combined with litter dust. If you or a family member is allergic to cats, this is likely the reason. An air purifier may allow you to hug your kitty without consequences, lovely!
Tips for Maintaining Air Purifiers
- Regularly Replace Filters: For proper functionality, regular filter replacement is mandatory. This will vary depending on what air purifier you got, and how much time it’s turned on. As a rough estimate, HEPA and activated carbon filters should be swapped in between 6-12 months. Replacing the filters regularly will also prolong your air purifier life.
- Keep the Air Intake and Outlet Clean: With use, air intakes and outlets can accumulate dust and debris that should be removed to avoid reduced efficiency of your air purifier. For this, you can use a vacuum with a brush attachment, also a soft cloth can suffice.
- Keeping litter boxes clean: Not regularly cleaning the litter box because you now have an air purifier is lazy, don’t be lazy! This will only make your air purifier work twice as it should. Avoid this to prolong the filter and air purifier’s use and life.
