Costco has a 2 pack for $59.99 after $20 coupon. This is a good deal for genuine Winix filters.

I'm seeing 4 pack generics on Amazon for under $9 each. Is the quality that much different?

This is the age old question. No one really knows. And there are many different generics so I am sure each performs differently.

Personally, I have been using generics. I have the c545 so filters are a little more expensive. The OEM ones claim to last for a year but I think thats BS. I usually buy the ones that comes with the 4 carbon sheets but I decided to buy a 4 pack of Hepas for like $18. I use one Hepa for every 2 carbon sheets.

Considering that my Winix has a layer of dust on it, I don't know if it matters in the scheme of things.

As the old saying goes ...crap goes in and crap comes out...why even bother using an air filter if you don't plan to put in quality filters? Completely pointless
Bet you don't buy generic drugs or anything. Just pay the premium for name brand everything. Perhaps you are in the wrong forums.

A comment like this shows your lack of understanding.... pharmaceutical industries are highly regulated...a generic alternative has been tested to meet the performance of the branded...a cheap knock off on Amazon has 0 testing for any actual performance...anyone could be a third party selling anything you want with any claims you want...use some common sense.

Our community has rated this post as helpful. If you agree, why not thank purewhiteasian

Bought these generics 2 years ago - https://a.co/d/fdlif7x. Had a good amount of allergies since I kept on using the official ones past the time it needed to be replaced (like +6 months) because the official ones are so damn expensive.

Felt less painful replacing these out sooner (every 6 months), so I end up replacing them more often since they were significantly cheaper. Both the official and this generic removed my allergies. So whether or not they are as good as the official ones, no idea since it's not worth buying an air quality monitor to test it, but it was definitely good enough for my allergies.

Note, we own two black cats and found out later we started to get more allergic over time to pet dander. So not horrible allergies, but enough to trigger eye itchiness and occasional sneezing. If you have something more serious health-wise, totally understand not to risk the generics.

It's not mentioned on the Amazon page, but since these are the "Filter A", this should also work for the C909 variant correct?
