Revainrating 5 out of 5

This filter fits Costcos winco air cleaner

I had troubles finding, once even ordering wrong filters, the S replacement filters.

There was a shortage of sorts and Costco was sold out everytime I looked. I will now be buying them here from now on.

Pros
  • Didn't have to drive to Costco to get replacement that was a perfect fit!!!
Cons
  • Some customers report that the filter does not fit perfectly, creating gaps that allow air to bypass the filtration system
