About this product
About this item [Coverage] Designed to clean spaces up to 3,120 sq. ft. in 60 minutes.
[HyperCaptive Filtration System] Combination of a pre-filter, deodorization filter, and HEPA Filter reduces 99.97% of 0.3 micron particles, including pollen and other allergens.
[Smart Mode] With its Smart Mode feature, the Airmega automatically adapts to its surroundings by adjusting fan speeds based on the room's air quality; That means your unit is energy efficient without compromising effectiveness.
[Eco Mdoe] When the air quality in the room remains purified for 30 minutes or more in Eco Mode, the fan will turn off to conserve energy, kicking on again when pollution is detected.
[Sleep Mode] When the Airmega's built-in light and pollution sensors detect that the room has been dark and the air clean for 3 minutes, Sleep Mode reduces the purifier's noise and power consumption.
