115115 HEPA Replacement Filter A for Winix Plasmawave Air Purifier C535 5300 5300-2 6300 6300-2 P300 AM90 C909 9800,2 x True HEPA Size 21 Filters + 8 x Carbon Pre-Filters

Perfect fit, and they are well constructed. I go through a couple of these a year when pollen and dry summer dust is blowing. Good, cost effective alternative.

Works perfectly in my air purifier! Fits great!

Reasonably priced replacement filters for my Winix Air Purifier. They’re equal in quality to the name brand filters. I appreciate this set with 2 HEPA filters and 8 carbon pre-filters and I always have them on hand. Replacing filters as needed help my air purifier work at its fullest potential. When I place the last filter in the purifier I place a new order so I’m always ready. Clean filters allow for less dust and cleaner air. With a big furry dog I need all the help I can get!!

The winix filters fit well. They were easy to install and to remove.

I order these frequently for my air filter I purchased at Costco.

These work great in my Winix (model 5300-2) Air Purifier. They work as good as the original filters, and they're more affordable than the replacements Winix sells. I am very happy with this purchase.

Perfectly compatible with our unit. Nice quantity so I don’t have to order as often.

Exactly as expected
