Stop Buying Fans Based on Airflow Specs
1 min read
Fan testing data shows airflow specs like CFM mislead buyers. Feet per minute (FPM) and oscillation matter more for cooling comfort. DC-motor fans cost less to run than cheap AC models. Bladeless fans are less efficient at high speeds. The Dreo TurboCool 765S hit 984 FPM; the Vornado Strata 8 Omni drew 13 watts.
