Nispira Replacement Filter S for Winix C545 Air Purifier – HEPA Media & Activated Carbon Filter Set

Just what we needed. . . the replacements fit wonderfully and have begun filtering the air as I write. Thanks for the affordable options!!! Here's to a healthy Spring.

It doesn't fit trying to figure out a return

Very decently priced air filters arrived sooner than promised. I love the way my home smells with newly installed air filters, easier to breath and take deep breaths.
