I love this air purifier system. I've been using this for 3 years, replacing filter every 6 or 7 months. I've had many types of air filters. This is the only one that absolutely gets rid of all the odor completely and immediately.
Amazon Verified Purchase Review April 1, 2025
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
That it works in unit over litter box
Great for cat odors in cat box
I had to move my litter boxes by my bed. I mounted this filter on the wall above the litter boxes. This sucks up the dust, and there is no smell. Awesome product.
The Purrified Air Filters keep me happy. My rooms with litter boxes are fresh smelling. You would not know I have 5 cats. Costly, but they work.

This is a must if you have multiple ferrets!!! The fire babies smell no matter how much you clean their cage, but this has been amazing in helping with that
I have purchased the Air Refill pack on several occasions and have consistently been impressed with the excellent customer service and the punctual delivery of my orders.
Good prices, fast shipping, items available from stock.
Produce works great at significantly reducing litter box odor!
The filters themselves have no smell to them so I don't have to worry about the air smelling funky when the purifier isn't on. Nice and hefty, no weird pellet drops when handling. I feel safe knowing this filter will actually remove bad odor...AND THEY DOOOOOO thank you guys so much
I am a regular user of these filters, and they reduce odors greatly! I intend to keep purchasing these on a regular basis.
Besides the Littler Robot. This air purrifier is the next best purchase. The filter lasts a long time and well worth the cost. I took their advise and this time spread the old filter media in my flowerbed instead of throwing it away. I would recommend this purchase for anything stinky.
Purrified Air Replacement Filter Cartridge
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.
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.
I went with name brand filter hoping it will last as long as first. I love the filter I have cats and allergy and this device picks up a lot of dust and dander
There is none!
Nada. Zero. Zip.
These cartridges last for MONTHS and work like you would not believe!. I can't recommend the system enough.
Received the filters in a timely fashion. Wish I knew about recycling the old filters in the garden ahead of time.
I don't fully understand how this bag of rocks really works. But it does. I change the filters every 60 to 90 days, depending on the location, and they work better than anything else I've tried. Great product and great customer service. Not inexpensive but worth every penny.
We have 3 cats and live in a home that is 700 square feet. Without this filtering system, our entire home would probably smell like a litter box. With it, you may not even know we have cats at all.
The low decibel motor and location options allow the machine to be placed in a way that doesn’t affect the cats whatsoever!
A+ product
Really helps keep smell down. We have 3 large cats
I searched trying to find a way to keep our small apt. from smelling like a litter box. Trust me hours, days, nights, weeks of research until at last I came upon this air purifier. Yup! It actually does what it says it will do! No more cat stink!!!
This purifier works really well. I wish there’s a 4.5 rating option. I’m actually rating it 4.5
I wish there’s another way of hanging this on the wall without having to drill holes on the wall when you live in an apartment. The unit + the bracket could not be held with 3M hanging tapes. :(
Hi LP, Thanks for the review. One thing some folks in the same situation have done is place a floor-standing wire shelf over the litter box and place the filter on the shelf. Or you could use a solid shelf in the same manner and place the filter in the bracket on the shelf.
