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

Fits

Got my new filters today and went to install the hepa filter. Took out the original filter that came with our unit and it showed the air flow direction on the filter. When putting the new filter in the unit, it did not say which way for the air flow. Checked all 4 sides and none shown. Other than that it fits just right and well see how it does in time.

Saved a lot of money but it ng these here instead of company. Easily go through 4 per year if air quality is bad

So easy and came so quicky

Prefect work with C545 air cleaner.

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

Easy to install and its a perfect replacement filters. Will order them again.

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

Perfect fit and good quality

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