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

I use these all of the time to keep our air circulation going all the time!

It works great and cheaper than from the company

Easy to install.

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

Prefect work with C545 air cleaner.

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.

So easy and came so quicky

No problem so far.

One of the smokiest fire seasons on record and our indoor air was dramatically clearer after installing new filter.

I have a very sensitive nose. However, these had a smell when they were in the purifier that made it smell like burning plastic. I switched back to the winix brand and the smell disappeared. Sadly i was past the return window, so now i have a bunch of garbage
