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

Got the winix air purifier from Costco a year ago and I needed to replace the filters after I used the extra that came with the box. These filters can be pretty pricey already so I decided to give these a try. They are exactly like the filters that came with the winix and they work just as well! Good buy and it comes With extra charcoal filters that you can replace regularly to keep the filter on longer.

Good value, easy to install

Functional I always order them.

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.

I am very frugal and like to at least vacuum them one time since they are expensive. They work very well and here in AZ it is quite dusty. I wish they were washable or reusable some how.

These filters fit and work perfectly in our Winex.

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 well - good value!

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

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
