Read on for the top 4 best air purifiers for cat litter & odors!

Best Air Purifiers for Cat Litter: What To Look For

Before we begin, here’s a teeny tiny glossary of terms:

  • HEPA filters: High Efficiency Particulate Air filters
  • VOC: Volatile Organic Compounds, or gasses and other non-particular chemicals that are stinking up your home (so…cat farts are VOCs).

There are several different types of air purification technologies. Each of these addresses pollutants in the air in different ways, and each is best for certain scenarios.

Six types of air purification technologies are:

  • HEPA Filter Air Purifiers: High Efficiency Particulate Air filters use a pleated material to mechanically filter out usually 99+% of dust, pollen, mold, bacteria, and other pollutants. HEPA filters are a must if you’re looking for the best air purifier for cat litter dust removal.
  • Activated Carbon Air Purifiers: Activated charcoal is a highly porous substance with a vast surface area per particle size. It is able to capture odors, VOCs, and other gaseous pollutants to clean the air. An activated charcoal filter is a must-have if you’re looking for the best air purifier for litter box odor removal.
  • Ionic Air Purifiers: These purifiers don’t filter anything at all. Instead, ionic devices release negative ions into the air to stick to particulates. Then, the charged particulates are supposed to be attracted back to a charged plate on the device. Aside from limited filtration and effectiveness, the real downside to ionic air purifiers is that they release potentially dangerous ozone. Cats are very sensitive to ozone, so it’s better to find a different air purifier option that doesn’t release as much or any ozone. If you purchase purifier that uses ionizing technology, check to make sure it can be turned off and be sure to remind household members that that feature can be dangerous for sensitive cats (and sensitive people as well).
  • 🆗 Ultraviolet Air Purifiers: These air purifiers use short-wave UVC light to inactivate mold, bacteria, and viruses. This type of air purifier is great if your concern is with germs and pathogens. However, UVC radiation has been shown to create ozone out of oxygen in the air. However, certain models of UV air purifiers have a modified coating on the machinery that lowers or eliminated the release of ozone. Since this doesn’t take odors out of the air as effectively as charcoal filters, and doesn’t remove particulates such as litter dust as effectively as a HEPA filter, UV air purifiers alone won’t get the job done. However, if an air purifier has a UV component, that’s a great addition as long as it doesn’t release ozone that could harm your cat.
  • Electrostatic Air Filters: This is a filtering layer, not to be confused with the electrostatic air cleaner below. This filtering layer, which tends to be cheaper than a HEPA filter, has electrostatically-charged fibers that trap particles in the air by causing them to stick with electricity. One major downside is that as the filter gets dirty, it becomes less effective. And the fibers are farther apart, so there’s the potential that more particles will leak through and the air won’t get as clean. This type of filter should be combined with other filters for maximum particle capture.
  • ❗️Electrostatic Air Cleaners: These purifiers use a different mechanism from the filers above, and draw air through a space in the device that has an electric charge. Particles in that air become charged, and then stick to oppositely-charged plates within the purifier. These filters work well when the filter is clean, but quickly lose efficiency with an increasingly dirty filter. Just like the ionic air purifiers, some electrostatic air cleaners can generate ozone. Look for models that are certified low-ozone or ozone-free – all the purifiers we recommend below are in those categories.

Air Purifier for Cat Litter FAQs

Can an Air Purifier Help with Litter Box Smell?

An air purifier can help eliminate smells from the litter box. This happens two different ways:
1) The smells can circulate throughout your home carried by particles. A HEPA filter will remove those particles from the air, thus decreasing the litter box stank. 2) Gaseous odors from the litter box area may waft through your home. An activated charcoal filter will absorb and eliminate Volatile Organic Compounds, whether they come from drying paint or your cat’s butt.

Can An Air Purifier Help With Pet Hair and Dander?

An air purifier will capture hair, dander, dust carrying odors, and other small particles floating around in the air. The air filter suctions up the air, processes it through one or a layer of filters, and blows out fresh clean air on the other side. A HEPA filter is the important elementof an air purifier for removing pet hair and dander. In addition to an air filter, vacuuming regularly with a HEPA-filter equipped vacuum cleaner will go a long way in eliminating pet hair and dander from your feline-loving home.

How effective are air purifiers for cat allergies?

Cat allergies are twice as common as dog allergies, and most people are actually not allergic to the fur of the cat. Instead, their immune system is overreacting to proteins in the cat’s dander, saliva, and urine. If your cat is an indoor-outdoor cat, he could also be bringing allergens such pollen in from the outdoors.
In any of these cases, an air purifier can help greatly with cat allergies. A quality air purifier will remove cat litter dust carrying particles of cat urine from the air. It will also remove dander, pollen, and other feline-related contaminants from the air. However, keep in mind that it may not be a complete solution for every allergic person trying to share space with a cat.
