Verdict

The Blueair Classic 480i is a high-performance air purifier built with a durable galvanised steel housing designed to service medium-sized rooms up to 40m² (434 sq ft), delivering 5 air changes per hour with a CADR of 510 m³/h for dust and pollen, and 476 m³/h for smoke. Powered by HEPASilent technology that traps 99.97% of airborne particles down to 0.1 microns, its main characteristics include integrated air quality sensors for auto mode adjustment, built-in Wi-Fi for remote app monitoring, and a low power consumption ranging from 15 to 90 watts. Key pros include an Energy Star rating, whisper-quiet operation at its lowest setting (32 dB), and efficient smoke, VOC, and allergen removal. However, main cons include a premium price point, ongoing 6-month filter replacement costs, a heavy 15kg footprint, and loud noise levels reaching 52 dB at its highest fan setting.
