C545 HEPA Replacement Filter S Compatible with Winix C545 Air Purifier, Replaces Part 1712-0096-00 and 2522-0058-00, 1 HEPA Filter + 4 Activated Carbon Filters, 1 Pack

Just got mine in and it fits my WINX model 5510 perfectly. You can do 1 carbon pad every month for 1 big filter every 8 months or you can do 2 carbon pads every 3 months to the 1 big filter 6 months. I like have the option. Quality of the product that's good. The value is good. Air cleanliness is better than the original, because yiubcan change the carbon filter every 2 months to keep the house smelling good. Functionality ilof the filters is perfect.

High quality filter that fits and looks exactly like the original for my Winix C545 and even has a handy pull tab at the top when it's time to change it. No weird smells or anything - just clean air. Will be ordering these from now on.

Fit perfect in my air purifier, great price, exactly as advertised!! Will repurchase

Works well no smell easy to replace

Nice, clean, and working.

My home has never had cleaner air. Super easy to use and easy to switch out. Seems to work just as good as OEM.

I was gifted a Winix C545 purifier earlier this year for reasons related to smells/odors from a tenant in my townhouse basement. After almost a year it was time to replace the filter (indicated by the warning light and the app telling me) I have it set to auto mode and after 10ish months it warned me to swap it.I decided to buy aftermarket filters because the Winix ones are over priced and don't make sense for the price you pay vs what you receive. These seemed to fit the bill as they were listed as compatible and the perfect replacement pair. So, I ordered some. 1 hepa filter and 3 charcoal pre filters.They came next day and were a perfect fit. I cleaned the outer shell, cleaned the pre screen under a shower head and dried it off and then swapped the charcoal filter and the main filter with no issue (pay attention to the direction and arrow for air flow). The sizing and fit were identical. I can't speak to the ability to filter out bad smells because some cooking is just to stinky. This purifier was in my bedroom and the amount of dander, lint, hair and dust that it had filtered was shocking. This was from the original filter. I'm sure the new aftermarket part will perform identical.I also have a washer/dryer in my bathroom (connected to my bedroom), so that doesn't help the lint situation, but the air purifier sure does pull it through and catch it.Time will tell how it compares to the original filter.(Just make sure you push the filter reset button for 5 seconds once you have swapped the filter out, this will start the cycle fresh, you'll need a pin/paperclip to push the recessed button on the top right of it).

Great product, I use these for my cats room.
