🌬️ High-Quality Winix 114290 Replacement Filter F for U450 Air Purifier Review

This is a genuine offer for Winix. It fits perfectly. Don't try to figure out how to customize a generic filter. These air purifiers also seem to work well. We love it and I vacuum filters for 1 to 3 months depending on how often we use it. There is so much debris in the air that we have to launch it quite often.

In my opinion this filter cartridge is quite expensive as it needs to be replaced once a year but it is still worth the price as it works very well. Just make sure you order the correct part number for your machine. This part number should be located on a sticker on the inside of the front panel of your Winix computer near where the filter is inserted. It's an all-in-one filter, meaning that activated carbon and HEPA materials are packed into one cartridge.

Have been buying it every year for a while. I have two U450 on 1000 sqm. ft. "Delete" is the wrong name. Simply vacuum the pre-filter regularly and replace the entire cartridge once a year. People ruin their filters by getting them wet when you should be able to. In the past they were cheaper through Winix with a coupon, but this time Revain was the way to go. Rather, I think they last longer in pet-free homes and aren't too wet. For cost reasons, I prefer 18-month intervals.
