Product Details:
- Designed to clean spaces up to 3,120 sq. ft. in 60 minutes
- Combination of a pre-filter, active carbon filter, and HEPA Filter reduces 99.97% of 0.3 micron particles, including pollen and other allergens. It also reduces volatile organic compounds and odor
- 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
- 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
- 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

You do need to run this at medium speed to get a lot of the benefits. Leaving it on auto doesn't seem to pick up as much dust as medium does. I think I read on Wirecutter that for any purifier, it needs to run at a certain CFM to really be effective and running most purifiers on something lower than their respective medium setting doesn't do a whole lot of good.
