The Breville 360 Autosense Air Purifier with True HEPA H13 filter removes up to 99.97% of dust, smoke, and pollen. The 360-degree inlet system cleans the air in large rooms up to 28 m² five times per hour. The Autosense feature displays real-time air quality. Three filter stages capture particles as small as 0.3 microns and neutralize odors. The sleep mode operates at just 35 dBA and turns off all lights. A reminder indicates when to change the filter after approximately 12 months.
