A Balance of Technology and Design

We saw an opportunity to change the way people viewed air purifiers.
By combining leading technology, inspired design, imagination and an obsession with detail, we created an air purifier that is as powerful as it is beautiful.

Green True HEPA™ Filter

Traps 99.99 percent of airborne particles up to 0.01 microns in size.*

*Coway air purifiers have been tested according to the Korea Air Cleaning Association standard on a particle size of below 0.01㎛ and on maximum fan speed in normal room temperature and humidity conditions. According to Airmega 250's test report, 99.999% of 0.01㎛ particles are removed within 12 minutes. (Tested with Airmega AP-1216L, AP-1512HH, 150, 250, 300, 400).

Activated Carbon Filter

Removes harmful gases, volatile organic compounds (VOCs) and odors from your indoor air.**

** Based on Coway’s internal data measured under the condition of JEM 1467:2013 standard. The actual performance will be determined by indoor air quality and operation of the unit.

Pre-Filter

The easy-to-clean pre-filter captures large particles like hair, fur and dust in its micromesh, so the dual HEPA filter can work more effectively.
