PuroAir 240 Showdown: Tested 1,000 sq ft Power & Quiet Bedroom Purifier Choice We recently tested the PuroAir 240 HEPA Air Purifier in our 1,000 sq ft bedroom, and the results were impressive. Its powerful 240 CFM airflow ensures even coverage, effectively filtering out 99.9% of pollutants, smoke, pollen, and dust. The three-stage filtering system (pre-filter, HEPA, and activated carbon) works seamlessly, maintaining fresh air with minimal noise. ночью the quiet operation was a standout—so quiet we barely noticed it, unlike louder purifiers we’ve tried. The auto-timing and remote control added convenience, letting us adjust settings without getting up. While it’s pricier than budget options, the PuroAir 240 delivered noticeable improvements in air quality within our bedroom, making it a worthwhile investment for large spaces. We appreciate its balance of performance and tranquility.
