The Purrified Air Litter Box Air Filter is our primary product. Nothing is more effective against cat, ferret and other small animal odor. Our Air Filter combines several proven (new and established) odor-destroying technologies, specifically targeted to pet odor, allergens and pet dander. It is adaptable to most covered and open litter boxes, ferret cages and mobile homes. Check which accessories you may need for your particular setup.


Accessories such as the Wall & Counter-Top Bracket or Dome Adapter are NOT included in the filter base price. This is done to save money for customers who only require the filter for their setup.

Full disclosure: It is so effective that you may forget to clean the litter box and have to set a reminder.

    Purrified Air is a Product Pick from Animal Wellness Magazine for 2020 for "Recognizing Superior Quality in Promoting the Wellness of Animals." We're not going to argue.

    Purrified Air is recognized by Animal Wellness as a Product Pick for "Superior Quality in Promoting the Wellness of Animals.


    The deep dive:

    The Purrified Air litter box air filter employs five-stage air filtration, using a combination cutting-edge and tried-and-true technologies.

    Stage one: a filter pad blocks dust from kicked-up litter from clogging later media stages and from escaping the litter box. Stage two: The filter pad is treated with a natural chemical called catechin. It is derived from green tea and is effective against microorganisms.

    Fun fact: You don't get green tea in a sushi restaurant just because it tastes good. Catechin, a natural chemical in green tea, is also known to kill microorganisms like bacteria which can be on raw seafood, preventing illness.

    Catechin is also effective in removing odor-causing and illness-causing microorganisms in the air. When weaponized by air filtration systems, catechin becomes an important phase of the Purrified Air Five Phase filtration system. Here is what the Mitsubishi company says about the catechin used in its air conditioner pre-filters:

    "Catechin filters get their name from a naturally occurring bioflavonoid found in green tea that has been used in traditional medicine since ancient times. Catechin — which has antiviral and antibacterial properties — is infused into every molecule of these filters, which enables them to strip the passing air of odor-causing pollutants such as tobacco smoke and pet smells. An equally important benefit is that they trap and deactivate microscopic bacteria and viruses, which can diminish or prevent the spread of some diseases."

    Stages three-five: A proprietary blend of 2.2 pounds (one Kilogram) -- 6 to 90 times more filter media than our three major competitors use* -- consisting of (Stage three) activated carbon, (Stage four) zeolite and (Stage five) negative ion ceramic balls. Activated carbon, in the right quantity and with the right air flow through it removes many VOCs (Volatile Organic Compounds) such as those found in cat waste. Additionally, zeolite is particularly effective against the odor-causing ammonia in cat urine. Negative Ionic ceramic balls are used because of their effectiveness in killing odor-causing bacteria.

    Does not use Ozone. Most Effective, Powerful, Adaptable and Quiet. Plus, lifetime guarantee on fan.

    * This finding is based on tests conducted November 2020, our filter media cartridge contains 6-90 times the filter media used by our competition. See accompanying photo for details.

    Works for smelly cat poo

    Amazon Verified Purchase review, March 23, 2022

    Bought to mitigate horrible poo odor from litter box that infiltrates HVAC system and invades whole house (small, single story, tightly constructed house). One of our cats has a dodgy gastrointestinal tract (possible IBD) and produces some of the worst smelling poos. Litter box is located in a cozy mudroom that can be closed from the rest of the house, however, when he goes #2, the smell creeps under the door even when closed and also into the air vent near ceiling. It is bad. It can wake the dead. Could probably patent it as a bio weapon.

    Bought this pricey air filter out of desperation during my extremely nausea-filled first trimester of pregnancy as the horrid smell would wake me from a dead sleep and keep me awake, and I’d have to rouse poor husband to clean the poo at 2am.

    We’ve only had it a few weeks so far, and run it right above the litter box all day. It sounds like a fan, but not overly loud. Even when dodgy-tum cat poops in the middle of the night, the smell, while still detectable, is now very tolerable and some nights we don’t smell it at all. Curious how long the filter will last and just the overall unit given the price. Time will tell.

    Worth mentioning we use a sifting box with pine pellets, so poo odors tend to be more noticeable, stinky poo or not. Pee odors were barely noticeable before and now practically undetectable.

    Significantly reduced cat urine and litterbox odors!

    Amazon Verified Purchase Review by Gerald M. Biggers on February 8, 2022

    Does what its ad claims - reducing cat urine and litter-box odors! PROS: Quite noticeable ("dramatic?") odor reduction in bedroom when running. Fan motor sound is not intrusive and can be adjusted up or down. Most importantly, the bag of odor reducing material to fit inside the purifier completely fills the compartment and is composed of carbon and other ingredients to absorb and/or destroy VOC odors. CONS: The exterior design somewhat resembles "take-home" meal containers, but not a real problem considering where it is to be placed to do its job!

    Purrified Air Product Group A

    Exceeded our expectations

    Definitely exceeding our expectations! We set the device up on top of our covered litter box (gladly removed the door for easier entry/exit for our two cats). Works as advertised. Excellent product and can’t beat the lifetime warranty! 5⭐️

    This is great, it helps reduce the smell and dust from the cat box. Didn't realize this would help as much as it has, I am a new fan and will continue to change this out.
