Medical-grade clean air for large rooms at the best value. Atem Eco makes high-performance, medical-grade air purification more affordable than ever, delivering large-room coverage up to 1,460 sq ft (136 m²) with HyperHEPA filtration and smart air quality monitoring. Its 360° air intake and cylindrical vortex system uses just 50 watts at max speed, while the eco-conscious frameless filter reduces plastic waste. A built-in PM2.5 sensor continuously monitors indoor air, while dual indoor/outdoor air quality indicators make comparison easy at a glance. With IQAir app integration, you can see outdoor data from your city, a nearby station, or your own outdoor monitor—so you always know what you’re breathing. Smart Mode automatically adjusts fan speed as air quality changes, and advanced filter-life monitoring helps maintain high efficiency and extend filter life.
