HR900 Replacement Filter Set Compatible with Winix HR900 Ultimate Pet Air Pur-ifier, Replaces Part # 1712-0093-00 / Filter T and 1712-0094-00 / Filter U - 1+1+6 Pack (Upgraded)

The size is a bit off and there is a lot less carbon in the carbon filter.

Good for the purpose.

This Winix filter works very well especially with dogs in the house. Amazing amounts of fur get picked up by the air filter and all the household dust etc is caught by the HEPA filter. Oh, it is HEPA BTW, I measured it with a calibrated laser particle counter because I am a nerd. I like the carbon filter as its big chuncks in a free flowing cage which works well and there is a non woven prefilter for everything. When I replace these they are pretty well loaded with stuff we would have breathed in. We are not too far from a wildfire area where the state self immolates every year and the skys turn blood red with smoke and debris. So we rely on our army of air filters to clean it up and it does. Takes out the smell of burnt stuff as well. But this is an expensive filter set to buy for name brand and I found this one works just as well, and thats testing it with my laser counter and my nose. Recommended if you have this model that uses HR900 and especially if you have shedders and big smelly dogs.

Everything fit perfectly and has been catching dust and debris. The pre filter is awesome but dang I don’t know what tape y’all using to make these, they are sticky like rat trap glue. Lol. The tape catches my hair, the polish off my nails and darn near my skin off my thumbs. I love them though

Outstanding product
