I have been using this filter for
Approx 6 years plus and I could not do without it after five years my unit stopped and I knew from the smell I order replacement ASAP and got it quickly and I am back in business

This is the only thing that really controls cat box smell. My cat does not bury his poops and omg . This is the best invention ever!! No smell !!

Good prices, fast shipping, items available from stock.

Works great. Air around the litter tray is circulated well and carbon filter removes all smells. Very happy with the purchase.

We have three extra large cats and only one litter box. We tried everything to reduce smell. There is almost no smell with this fan. It's amazing. Pretty cool to see the video of how they make these by hand in their garage. Thank you!!

We have six cats and seven litter boxes. The most used have these filters running 24/7. One of those is within 6' of the front door. Guests don't know we have cat's until one strolls by.

The customer service is excellent standing behind the fans which have a lifetime replacement. Per them expect to change the filters ever 4 - 7 months.

Uodate: I am editing my review regarding the price. I mistakenly ordered two three pack sets vice two. I did not notice the description defaulted to the three pack. So apologies as the filters are ~ $48/per not $126. Looking at the positive we will have filters for some time.

Bumped to 5 stars.

Highly recommended

I have two cats and their litter box is in a very enclosed space. Litterbox odor has always been a problem. Now I never smell it! LOVE THIS PRODUCT!!

I turned it on and within a few hours i could tell the smell was down. When someone uses the litterbox i also think it helps bc its not waking me up out of bed.
I don't have it set up so its on top of the box like recommended, but its immediately next to the litter boxes. i definitely think it’s doing its job.

This is fantastic. I have the litter box in the guest bathroom. I was worried it would just smell like litter any time someone goes in. But this device is small but mighty. There is no unpleasant odor in the bath. I have been a cat pet owner for 40 years. I wish I would have had this much sooner.

I can't believe I didn't purchase this earlier. My litter box area (AREA!!!) has been fresh ever since I turned this on and let it run for a few minutes. This is a necessity for anyone living with cats, rabbits, ferrets...thank you soooo much my home has never smelled cleaner!

This air filter was gifted to my household after a long struggle with litter smell. We have a cat with kidney disease, so her business is much more "potent" than your average cat and it was taking over the house. We were scooping the box twice a day, doing a full change weekly, keeping windows open, trying various deodorizers and home air fresheners. My poor partner's nose is more sensitive than mine, so even when I couldn't smell anything he would still be bothered by it. Nothing worked until Purrified Air, the smell is gone and only faint when you approach the litter box. We'll even forget to scoop for a couple days every once in a while, that's how effective it is compared to before. The cats adjusted to the sound of the fan quickly, it's not terribly loud at all. Though it was gifted, I would've bought it myself even on a tighter budget because it's worth every penny. The filters are long lasting, we only need a couple in a year, so the refill price also feels very worth it. I have zero complaints, this has been a miracle product and vastly improved our quality of life!

This is the 3rd one I’ve bought. Now my adult daughters each have one. Works really well.

My original purchase of the Purrified Air unit included one extra replacement filter cartridge. I think each filter cartridge may have lasted almost a year. After I discarded the second replacement filter, I made a mental note to myself to purchase new replacement filters. Well, I am forgetful so things tend to languish on my mental To-Do for an excessively long time. It's been a couple of weeks now that I have not been using the Purrified Air unit because I've needed to purchase replacement filters. If I had ever had a question about whether Purrified Air was effective or not, today was the day All. Was. Revealed. to me. OMG, I felt that I should not be in the room with the litter box without wearing a hazardous waste suit for protection. The smell was awful. (I know that many of you know what I'm talking about.) After cleaning the litter box today, I marched right over to my computer and put in an order for three more filter cartridges. I have tried other products to absorb or remove the smell of the litter box. Nothing I tried before has really been effective in removing litter box odors. I recommend Purrified Air to anyone who has a litter box in their house. Wave to me if you see me outside standing next to my mailbox. I will be waiting for those replacement filter cartridges I ordered to be delivered. I don't want to go in the house with that smelly litter box. It is Scary.

After moving the litter box to a more obscure location at the back of the house, I noticed the house had an unpleasant order upon entry. Then realized the new location was right under one of the ac intake vents. Added this quiet workhorse directly over the litter box and it completely eliminated pungent, as well as more subtle litter box odors. I actually set up my sewing equipment adjacent to this space and detect no odor from the nearby litter box. Worth the money! But note, the wall brace is a separate purchase, so consider that when placing your order.

Please continue to make your filters! These are the only ones that actually work on cat litter box odor. Thank you for your commitment to making a product that actually WORKS rather than a marketing gimmick. Also, I had to have you service my fan recently, and the experience was easy and quick. Once again, you delivered on your promise of lifetime fan maintenence/replacement. How refreshing to encounter a company that cares more about its product and customer service than a quick buck. 5 stars.
