HR900 Replacement Filter Set Compatible with HR900 Ultimate Pet Air Purifier, 1+1+6 Pack (Upgraded)

perfect fit, great price

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

I will absolutely buy these again. It was really hard to find a good review based on filter quality, but I am so glad I purchased these. They are such a great replacement for my winnix. Easy to install. No bad smell. Functions wonderfully and the price is a relief! The air quality was noticeably better within ten minutes! Everyone keeps giving bad reviews based on the pre-filter's adhesive and difficulty to remove. This has nothing to do with the filter quality. Just don't peel the sticker off and just lay the filter on top of the other filters. Close the unit and it works beautifully.

Great filtration fits perfect

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.

Perfectly working, for the complaints about the pet filter being too sticky , just don’t stick it to anything and don’t peel the sticker cover off.

These are awful. The adhesive is so strong that it is very hard to remove them from the frame. It left behind residue that I couldn't remove with alcohol, oil or soapy water. I've tried scaping it off and still have adhesive residue. Thay are also thicker than the ones made by Winix so I'm not sure if they put more strain on the air purifier.

Great notepads to put on the fridge for lists
