Description of Coway Smart AP-1012GH Air Purifiers

The Coway Smart air purifier represents a great value for under $250. There are four types of filtration; pre-filter, carbon filter, and HEPA filter and a negative ionizer enhances the particle removal efficiency. The pre-filter traps large particulate like dust and hair; the carbon filter will reduce common household odors and gases, the HEPA filter will remove microscopic particles such as allergens, mold and bacteria. The negative ionizer can be turned on manually and is used to safely freshens the air by using negative ions. An air quality sensor regulates fan speeds while in the Auto mode and a color coded LED light display informs you to the level of air pollution. Blue means clean air, dark purple means polluted air and red indicated highly polluted air. Cleans up to 256 sq. ft. 3-year warranty.
