This kit is an off brand but I have no problems, I own 4 Winix 5500 air purifiers throughout my home & these kits are well worth the price - they keep the air smelling great & clean, also keeps dust down which is a huge help when cleaning. These are a great price point for the kit, 3rd time I have purchased total 5 stars 🌟. YES get them! Read more

I have used these HEPA and Hardcased carbon filters for years on my Winix 5500-2 air filters. I put a "sheet type carbon filter" (8-Pack Activated Carbon Pre-Filters bought on Amazon) just behind the machine's "dirt and dust screen" and just before the HEPA filter; and I put the washable hard case filter in this set behind the HEPA filter before the fan assembly to help with any residual odors ( we have pets). These filters catch all particles that go through the screen and prolong the life of the HEPA filter. Even after a year the HEPA filter looks good-- just a darkening of it a bit, so it has been doing its job for longer than expected. Read more

These are a great set of filters for the four air purifiers that we have in our home and they do a great job of filtering the home's air and are a direct replacement for the OEM ones. Super easy to install and with the pull tabs they have on the carbon and HEPA filter, changing them is a breeze. New filters help to keep the air purifiers running quietly as they do their job sucking up pet dander, pet hair and dust. The new activated carbon filters are a bonus as they do make a difference when removing odors from cooking. Read more
