Key Features of the Coway Mighty AP-1512HH

1.  Four Stage Filter Process

The best and main feature of this device is its FOUR stage filter. We have broken down the benefits of each filter for you to understand why this air purifier may be a great choice for you and your family.

The pre-filter has active carbon components that act effectively to catch on any dust particles and it is also responsible for catching large particles such as hair. This filter can also be cleaned easily at home.

2. Smart Sensor

We love the Smart Sensor on the Coway AP 1215 HH air purifier. When switched on it senses the quality of air in your home and switches to a higher or lower setting according to the cleaning requirement of the environment.

Of course, you have control over this too as you can also change the settings manually. The device’s sensor also lets you know when the necessary carbon filter change is required.

3.  Power Consumption & Timer

The device only requires seventy-seven watts of power with minimal noise range only up to 53 dB. And the timer feature lets you set up the operation of the device for specific hours (1,4,8 hours) before automatically turning off

4.  Coverage

The Coway Mighty covers an area of about 361 square feet, so that equals to about a living room or a moderate-sized apartment. When thinking about where to position the unit,  the fans pull in the air through the slits in the front, the air then passes through the filters and is released back from the top.

5.  Design

Coming in two colors black and white, the sleek design makes it a perfect fit for a stylish home.


From reading the reviews available on the internet, most users of the Coway Mighty air purifier seem very happy with their purchase. 

Absolutely love it

Very sensitive, kicks in automatically when I'm cooking

Definitely notice a reduction in dust around the home

On the most powerful setting, it does vibrate a lot, enough for it to fall off a table!
