Our Purrified Air replacement filter cartridges come in a sealed vacuum bag for long-term storage.
Filter media cartridge contains 2.2 pounds (one kilogram / 35.2 ounces) of a proprietary blend of activated carbon, zeolite, catechin, and negative ion ceramic balls, plus a filter pad to capture kicked up litter dust and pet dander.
In April 2022 we introduced a new "tackifide" filter pad treatment which captures more dust and dander, and also provides a more potent catechin phase. We borrowed this technology from the furnace filter industry. Furnace filters with an application of a tacky coating capture more dust, dander and other particulates.
We know our filter media refills are not cheap. Here is a way to get double the value out of them. Turns out the primary ingredients of our filter media packs -- activated carbon and zeolite -- are excellent soil enhancers for plants. Both absorb excess water and slowly releases it as the plant requires, preventing root rot. Zeolite takes the ammonia in cat urine and turns it into nitrogen-based plant food. Activated carbon rids soil of impurities, repels insects, and prevents mold and odors. To apply, cut open used media packs, and mix into soil at a rate of about one part filter media to 10-20 parts soil. That’s roughly one cup per medium size flower pot or two cups per cubic foot of soil in the garden.

Customer Reviews
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.

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
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.
