Your beloved pet can fill the place with pet dander, or you may live with a smoker and want to get rid of the tobacco smoke. For some people, you may have a small space and you may have to deal with the smell of food filling the entire space whenever you cook. You can get rid of potentially harmful gases in the air or anything that can cause respiratory issues or allergies.

Purifying Mechanism

There are four stages that the Coway ap-1512hhmighty air, purifies the air in your space. The first is a washable pre-filter. At this stage, larger airborne particles are trapped, like fur, and dust. The second stage is the odor filter which uses an activated carbon filter to trap odors, smoke, gas, and generally smaller air pollutants that would have managed to get past the first filter. 

The next stage is the true HEPA filter, which the manufacturer claims, traps up to 99.97% of allergens that could be harmful to you. This filter will trap allergens as small as 0.3 microns.

The next and final step is the vital ion feature, which is what cleans and freshens the air. It does this through an ionization process where negative ions are released into the air, where they undergo an electrochemical process which then renders any pollutants in the air, harmless.  Together. These four, clean the air effectively.
