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

Worked

Easy to install.

They are exactly what I was looking for.

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

A good value; fits the Winix C545 purifier just like OEM. I liked that there is an option to just purchase the filters and not charcoal filters as I dont really care for those.

Fits

It was easy to switch out. It fit perfectly as described, and the air flow through the filter and pad provide great air quality.

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

These filters fit and work perfectly in our Winex.

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