Review on 🧼 isinlive True HEPA Replacement Filter A 115115 Size 21 Compatible for Winix PlasmaWave and Fellowes AeraMax Air Purifiers, 2 HEPA + 8 Carbon Filters by Brian West

We have several Winix air purifiers [wildfire smoke and 6 rescue animals - dogs, cats and big birds]. Therefore, we go through many filters. I ordered several boxes of Winix branded replacement filters from Costco the same day I ordered these clones from Revain. When all the filters arrived, I opened them up and compared them. VERY similar construction, quality, fit and finish. With the exception of the Winix's front tongue, they looked the same. I haven't changed it yet, so I don't know about durability. We've vacuumed them several times and everything seems fine. These "cloned" filters were MUCH cheaper than Costco's Winix brand filters [which had the BEST price for Winix brand filters].
