🌬️ Fil-fresh 2-Pack 115115 Filter A - Compatible with Winix C535, 5300, 6300, 5300-2, P300 Air Purifier - Includes 8 Carbon Filters Review

I've seen other people point this out but I didn't trust them. So I ask you to trust me and not the 4.7 star rating. This is a lower quality of the original filter and lower quality than some other brands. It will work in a pinch, but will likely need to be replaced more often.

Product list C545, filter is MUCH large for C545. Rather than deal with returns to crowded delivery locations during the pandemic when people aren't wearing masks, I'm cropping them, need to do while I can find the right C545 item. The black pre-filter is also about half as thin and less dense than the one that came with Winix.

I don't believe charcoal filters are actually charcoal. I'm pretty sure it's just felt material. In my photos, on the left is the original filter that I bought from winix. The product I bought from Revain is on the right. It's not as hard and scratchy as the original. I suspect because it's not coated or impregnated with real carbon, which determines the actual point of the filter.

Nice to get filters at half price but the packaging doesn't say they fit my model and there are a lot of Chinese typos on the packaging. It's fine, but if they can't pay an English speaker to review their marketing, who knows what other things might be overlooked that might affect the quality or the ethics behind this product. Back to brand filters.

Purchased for our Winix C535 cleaners (purchased from Costco) and they look almost identical to the OEM product. Both carbon and pleated media look and feel the same (same quality). And they fit just like OEM filters! Nice and tight in our two C535s. 2 complete sentences. A total of 8 flat carbon filters and 2 pleated HEPA filters. If you have a C535, save your money and buy it!

The activated charcoal filters were so thin that I could easily install a Hepa filter and 4 activated charcoal filters in the car. I could look through them and see the other person's features. It was just ridiculous. I've ordered them before and the charcoal filters weren't that flimsy. The price has gone up and the quality has gone down significantly. Hepa filter is ok. They added a thin layer of material on one side of the hepa. Once that layer is clogged, say goodbye to hepa. I use them…
