Manufacturer-source decision brief · Checked 2026-10-04
US Winix product pages and the shared 5510/5520 manual, revision 02, checked for room coverage, CADR, replacement filters and rated power. Manufacturer ratings are not our own performance measurements.
Winix rates the 5510 for 392 square feet at 4.8 air changes per hour under its stated test conditions. Our interpretation: compare coverage at the same air-change rate, rather than choosing the largest advertised area without its time basis.
Winix 5510: specifications and room-size conditions ↗The 5520 also lists 392 square feet and dust, pollen and smoke CADR values of 252, 247 and 253. Our interpretation: these figures do not establish an airflow upgrade over the 5510. Look at the actual package, appearance and replacement-filter availability.
Winix 5520: specifications and room-size conditions ↗The shared manual specifies Filter Q and 65 W for both models. We corrected the 5520 catalog figure from 50 W to 65 W. Our interpretation: a rated-power figure is not a measurement of energy use in every fan mode; it does not establish a running-cost winner.
