Here’s what you can expect from the Coway AP-1512 air purifier.

4 Stage Filtration

The cleaning process involves a BAF-certified (British Allergy Foundation) 4-stage filtration process – pre filter, carbon filter, true HEPA filter, and ionizer. Through these filters, pollutants and allergens are surely eliminated.

How do the filters work?

The washable pre-filter targets large particles such as dust, fur, and hair. The carbon filter neutralizes odors and harmful gases, and captures smaller particles. The true HEPA filter is designed to trap allergens and other particles (pet dander, pollen) whose size can be as small as 0.3 microns. That last filter is called the Vital Ion feature, which freshens the air with negative ions.

Real-Time Air Quality Monitoring

This feature eliminates the guesswork by sensing and displaying the air quality of your room. Be guided by the following colors: blue – clean, purple – medium polluted, and red – highly polluted.

Auto and Eco Modes

When the air quality is detected to be bad, the Coway AP-1512’s auto mode adjusts the airflow speed to cope with the pollutants. If there are no pollutants detected for 30 minutes, this air purifier utilizes the Eco Mode. Meaning, it will automatically stop to save energy.

The Coway AP-1512 is designed to cover rooms of up to 361 sq. ft. It has been given a CADR rating of 233 (smoke), 246 (dust), and 240 (pollen).

Aside from those, this air purifier is also equipped with a Filter Replacement Indicator. Plus, it comes with a timer (1, 4, 8 hours).

How does this product fare among consumers? To complete this Coway AP-1512HH Mighty air purifier review, we’re giving you a summary of feedback and comments given by previous buyers as posted on a popular online retailer.


The Coway AP-1512 air purifier has been described to be well-built, perfectly sized, and attractive. It’s not that tall. It’s not too deep either. It can be placed in any part of the house without being an eyesore, as one person has said.

Airflow Design

Aside from having a nice exterior, this air purifier has also received positive comments regarding its design relative to airflow. According to one person, the Coway AP-1512HH circulates clean air by pushing it towards the ceiling, fanning it down the walls, and then toward the floors, then back to the unit.

This mechanism is advantageous because you don’t have to worry about finding where to “properly place” this device, unlike with other brands that push air from one side to the other.

Odor reduction

Does it filter out smoke? The general consensus is that it does pick up most of the bad smell, including cigarette smoke and cooking smell. As one person has said, you’ll need a larger charcoal filter to totally eliminate cigarette smoke in the house. Besides, if you’re an active smoker, expect a lingering smell.
