Winix Air Purifiers
Winix air purifiers combine a true HEPA filter, an activated carbon filter and PlasmaWave ionization you can switch off.
How to choose a Winix
- C909: a Costco version with Wi-Fi and PlasmaWave. It shares its filter pack with the C535.
- C545: a compact, lower-priced model for bedrooms.
- Tower XQ: a tall, slim Costco model for tight floor space.
- PlasmaWave: it can be turned off with a button if you want to avoid ionization.
- Filters: always match the part number printed on your unit.

FAQs
Which Winix air purifier is best?
It depends on room size and store. The 5500-2 and 5510 suit medium to large rooms and have thick carbon filters. The C545 is a compact bedroom choice. At Costco, the C909 adds Wi-Fi. Compare each model's AHAM CADR with your room's area times 0.67 and check the filter price.
Is Winix PlasmaWave safe?
Winix states PlasmaWave models are certified by the California Air Resources Board, which caps ozone emissions from air cleaners at 0.050 ppm. If you prefer no ionization at all, PlasmaWave can be switched off with a button and the purifier still cleans through its HEPA and carbon filters.
What is the difference between the Winix C909 and 5500-2?
They use different filter packs, so the replacement filters are not interchangeable. Compare CADR, noise and filter price, as both target similar room sizes.
