This air purifier has a timer and pet lock that prevents system settings from changing in case your cat accidentally knocks it over. It has a modern design and an ultra-quiet fan that enables it to blend into any room. It’s also relatively affordable when compared to other air purifiers. However, it has a pretty small room coverage capacity. So, it performs best when it’s placed in smaller areas, like bathrooms, laundry rooms, and mudrooms.

If you’re looking for an affordable air purifier, the Dirt Devil Air Purifier is the best air purifier for cat litter for the money. It has a simple and straightforward design that traps 99.7% of common allergens like dust, pollen, pet dander, and cooking smoke. It uses an H13 HEPA filter and a carbon filter that work together to reduce airborne particles and cat litter odors.

This air purifier has a compact design so that you can place it either on the ground or on tabletops. It works best in smaller rooms and when placed near a litter box. Fortunately, it’s quiet and non-disruptive, so it won’t bother or scare your cat. Therefore, even though this air purifier doesn’t have additional fancy features, it’s reliable, and you can depend on it to get the job done.

This air purifier works quickly and can fully rotate and purify air within 30 minutes in an 800-square-foot room.

This air purifier also has laser-sensor technology that adjusts fan speeds automatically to conserve energy, and you can adjust settings with the accompanying mobile app.

This compact air purifier is perfect if you have kittens in the home due to its unintimidating size and low noise level. It’s designed to sit on desktops or countertops and takes up very little space. Despite its small size, the GermGuardian AC 4100 is powerful and can remove up to 99.97% of dust and allergens.

Buyer’s Guide: Selecting the Best Air Purifier for Cat Litter

These days, you can find air purifiers with all kinds of features, and it’s easy to get lost in all the details. Staying focused on several key features can help you stay on track and find the best fit for you. Here are some important things to keep in mind when shopping for a new air purifier for cat litter.

Odor Control

Reducing odors is usually a priority for cat litter box issues, but not all air purifiers perform equally when it comes to odor control. So, make sure that the air purifier that you select has a filter that is specifically designed to trap odors. Most air purifiers that are designed for homes with pets have features that help with pet odor control.

Having a cat means dealing with occasional bad smells and messes. You can make that job easier with a great litter additive like Hepper's Advanced Bio-Enzyme Cat Litter Deodorizer, a natural product that uses bio-enzymes to eliminate odors.

Room Coverage

Air purifiers of varying sizes and fan speeds will have different room coverage capacities. So, if your cat’s litter box is in a smaller room, like a bathroom, then a smaller air purifier with less room coverage will suffice. There’s really no need to purchase an air purifier with a room coverage that greatly exceeds your room’s square footage. So, you can end up saving on costs by choosing an air purifier that’s appropriately sized for the room you plan to place it in.

Replacement Filters

Along with budgeting for initial costs, it’s important to consider how much you’ll spend on replacement filters. Replacement filters usually have to be changed between 3–12 months. The frequency will depend on the quality of the filter as well as your room’s air quality. So, make sure to check an air purifier’s filter prices and lifespan before purchasing an air purifier. It’s possible to save on costs in the long run if you purchase high-quality filter replacements that are designed to last longer.

Conclusion

Out of our reviews, the LEVOIT Core Pet Care True HEPA Air Purifier is the best air purifier for cat litter because of its versatile multi-filter system and relative affordability. The Dirt Devil Air Purifier is an excellent budget option that has a straightforward design and consistent delivery. If you’re looking for a powerful air filter with many helpful features, the Alen BreatheSmart 45i Air Purifier is worth the investment.

Choosing the right air purifier can help immensely with maintaining your cat’s litter box. It’ll also ensure that your house is free of odors and common airborne allergens.
