My check filter light came on 4 days ago on all 3 of my Winix purifiers. One 5500-2 and two AM80s.
Just put a generic set in the AM80s that cost $34.99 for both machines.
Happy with them so ordered another set of 2, and a set of 2 of a different brand to see if there is any difference at all between the multitude of brands with crazy names that Amazon sells.
I am happy with the ones I got so far. I vacuumed the charcoal thoroughly to remove any loose dust. The HEPA had a slight odor for 5 minutes, then it was gone. Quality of the appears good. Can't see paying more than double for these original ones.
Will see how the next 4 look. I'll use one, then have three ready for next year.
That's what's frustrating about these filters. Producing activated carbon and getting HEPA certification isn't cheap but it's not nearly enough added cost to justify $80 for a filter replacement. The margin on these replacement parts are too high for my taste. Unfortunately there is physics that makes HEPA filters capture PM 2.5 where other filters either can't or do so poorly and there is physics that makes activated carbon absorb odor. There's no way of knowing if a generic filter meets this standard.
That makes this a slick deal IMO.

It's just a generic looking black sheet.
Don't know what to make of it. Is anyone else getting these?

So it is sort of the wildwest in terms of third parties but anecdotally, seeing people on reddit who say they have bad allergies and using 3rd party doesn't feel different makes me think your comment about "yes they're not certified" as not quite as relevant as I might have feared.
Curious -- do you know of certification that actually exists? Or are you just speaking generally, that yes, a crap offbrand one can be really bad which I'm aware of.
