Description of Coway Mighty Air Purifiers

Take control of your homes air quality with the Mighty air purifier by Coway. A powerful yet extremely quiet fan moves air through the purifier’s 4-satge filtering process; a washable pre-filter, carbon filter for odor, a HEPA filter for microscopic particles and a manually controlled Vital Ion filter for air freshening. An intuitive color-coded light system is used to visually display the level of pollutants in your room. Blue means clean air, dark purple means polluted air and red indicated highly polluted air. An Auto mode utilizes a smart particle sensor to identify the current pollution in the air and will automatically raise and lower the fan speed as needed. There is also an eco-mode which automatically puts the fan into standby mode when there are no detectable levels of pollution. The Coway Mighty also features a filter change indicator light and a timer that will turn the purifier off after 1, 4 or 8 hours. Features a 3-year manufacturer's warranty.

  • Wants a healthier home

The Coway Mighty air purifier quietly cleans the air in your choice of room up to 326 square feet. This little air purifier is small in size but offers impressive filtration at a value oriented price. The controls are intelligently laid out and it features an automatic mode of set-it and forget-it operation.


  • Auto mode allows the Mighty to base its operation upon the quality of your air.
  • A visual air quality indicator uses a simple light system to indicate your current air quality.
  • Impressive effective coverage area of 326 sq. ft. is big enough for most bedrooms.
  • A 4-stage filtration effectively removes common airborne particles.
  • A money saving Eco mode automatically stops the fan if no air pollution is detected for 30 minutes.
  • An ionizer can manually turned on to freshen the air.


The Coway's tagline of "We bring Wellness" is not an understatement. Our product testing showed an impressive particle removal efficiency for a small air purifier at a value oriented price. We think that this air purifier is a very good purchase for smaller rooms in the house such as bedrooms and smaller living rooms. It should be placed in rooms no bigger than 18' x 18' but will be even more effective in smaller spaces. It's operational noise is very quiet and should not disturb activities such as reading, conversations or television viewing. The bottom line is that there are not many air purifiers that have incorporated so many features into one appliance with as impressive of a coverage area.
