Our Verdict

Winix C909

Winix 5530

The Winix 5530 and Costco-exclusive Winix C909 are very evenly matched in overall particle filtration performance. The C909 has a clear advantage when it comes to quieter operation, delivering stronger low-noise particle filtration and running considerably quieter at higher fan speeds. Both are similarly quiet at their lowest settings and offer app connectivity, automatic fan adjustment, and Winix's optional PlasmaWave ionization technology. However, the 5530 takes up considerably less floor space, making it easier to fit along a wall or beside furniture.
