Filter-Monster 115115 Filter A Combo Compatible with Winix Plasmawave

Looks like an OEM part so it'll fit and do the job

This is perfect! I realized the Winix-branded replacement filters for my Plasmawave were quite expensive, and it was good to find this compatible filter at a much better price. Just make sure you check your air purifier model number and see which filters are compatible with your unit. While the HEPA filter needs to be replaced about once a year (about 10.5 months in my case), the charcoal filters should be replaced quarterly, and this package includes the charcoal filters too. I actually think this compatible filter is a little nicer than the Winix original, and it has an extended frame/edge that holds the charcoal filter in place better. My purifier is humming along quietly and happily.

Nothing to dislike, it is a replacement filter and much cheaper than the actual site for the item by over 40.00. I first checked the Winix site and was able to attempt to purchase the replacement filter and charcoal type filters for over 79.00. I then found it on Walmart for 35.00 so I picked up 2 sets to give me a 2 year timeframe.

Not the correct filter Was a little too small didn't seal was way heavier than the real kind had to replace with Windex filter it is not compatible
