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

Have purchased twice. They seem to do their job. Install is easy.

Light came on to change air filter so ordered these so I don’t run out again! Work fine and would buy again!

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

Prefect work with C545 air cleaner.

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

The black charcoal parts are too big and the white fliter its self is wayyy to small and leaves gaps. Don’t waste your time

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.

These filters fit and work perfectly in our Winex.

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

No problem so far.
