PUREBURG Replacement Filter Set Compatible with Winix HR900 Ultimate Pet Air Purifier, H13 HEPA + Activated Carbon Filter + 6 Pet Hair Pre-Filters 3-Stage Filtration

I have allergies and pets and use HEPA filters to keep the air free of pet dander and dust. I have three units that need the filter replaced every few months. I usually order them from the manufacturer and the filters arrive in a sturdy box; this time in trying to save money I ordered from this site and the filter was crushed in shipping. It had been placed in a plastic bag. Even though I can't use it, the filter does look and feel like the original manufacturers filters. I'm sure the seller will replace it for me.

I dreaded every year I would have to buy an expensive filter replacement from Winix. But this is the EXACT same filter. I like that it comes with several of the monthly thin filters.

Perfect HEPA/carbon filter combo for my Winx air purifier. Fits perfectly and works nicely at a better price than the OEM version. Was shipped quickly as well. Would buy again.

I've been buying the replacement filters for my Winix Air Purifier for a couple years. My nephew has allergies and the filters with the extra pet pre filter really help.

Was a little worried not buying the winx brand, but it's working and it fits.

Perfect fit. The HEPA filter is visually indiscernible from OEM filter. The carbon filter has far fewer and smaller beads than the OEM carbon filter. The pet hair "pre" filter is a tighter weave and stiffer material than the OEM pre filter.

The black filter wasn't sealed and look like it was used before ,i could see some dust inside and outside !

A great HEPA + carbon filter. Love my Golden to death, but she would be the death of me with my allergies, This works great and along with the pet pre-filter, helps with my sneezing.
