Filtre de remplacement Winix F authentique pour U450

Replacement filters worked perfectly

Wayfair is the cheapest place to find this OEM air filter. Not a third party knockoff for a great price.

I had to return the amazon filter that did not fit though it was advertised to fit. This one I ordered from Wayfair did fit perfectly. Looks like it was stored in a hot place though because the plastic grid that holds the first level of filters (shown in the photo on the outside of the cassette) was deformed, wavy on the thin plastic vertical grids. But it was otherwise ok and it works fine. Happy with purchase. Will buy again.
