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

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.

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.

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

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

Works as they need too

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

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!!

This A filter fit my Winix air purifier perfectly and was easy to install.
