Coway Air Purifiers for Large Rooms up to 3,120ft²

The Coway Airmega 400, an advanced air purifier developed by Coway, intelligently, effectively, and quietly cleans the air in your home. With its HyperCaptive filtration system, it removes 99.999% of particulate matter from the air, while the accompanying pollution indicator allows you to monitor and manage air quality in real-time.

Designed to clean spaces up to 1,560 sq. ft. in 30 minutes, the Coway Airmega 400 features smart mode (auto, sleep, eco) and real-time air quality monitoring, ensuring that it is always working to maintain optimal air quality. The combination of a pre-filter, deodorization filter, and True HEPA Filter reduces 99.999% of 0.01-micron particles, including pollen and other allergens, as well as 99% of volatile organic compounds and odor.

The Smart Mode feature allows the Airmega to automatically adapt to its surroundings by adjusting fan speeds based on the room's air quality, making it 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.

The Airmega's Sleep Mode reduces the purifier's noise and power consumption when the built-in light and pollution sensors detect that the room has been dark and the air clean for 3 minutes. The 24/7 pollution monitor tracks air quality throughout the day, adjusting purification to the necessary level and saving energy when it's not needed.

The air filter indicator tells you when the filters need to be replaced and the prefilters need to be cleaned for maximum efficiency, based on how much air they have processed. You can also schedule the unit to purify for 1, 4, or 8 hours of use and conserve energy.

With a 5-year Limited Manufacturer's Warranty, the Coway Airmega 400 can provide 4 air changes per hour in a 780 ft² (72 m²) space, ensuring that your home's air is always clean and healthy.
