4 Pack C545 Replacement HEPA Filter Compatible with Winix C545 , Ture HPEA Filter S Only, Part number 1712-0096-00

Fits

How can I tell the front from back? Last filter was marked with an arrow. This one is not marked.

So easy and came so quicky

Ease of ordering, the correct item, fast.delivery, fits on air purifier, everything is great

Does what its supposed to do.

Easy to install.

Doesn’t fit as snugly as the filter I removed. Makes me question the quality. Only time will tell!

No problem so far.

These HEPA filters fit my Winix air purifiers perfectly, and cost way less than reordering through Costco or Winix directly. I only needed the HEPA filters, not more charcoal filters, so was happy to find these. They seem to be working well.
