Compact, four-stage filtration air purifier with HEPA

The Coway AP-1512HH Mighty air purifier is a great choice if you have pets, live in an area with high pollution, or have any sort of respiratory condition like severe allergies. The Coway is relatively compact and stylish, so you have more options about where to keep it. Additionally, the smart technology monitors everything about the unit for you, so you don’t have to always remember when to change the filter and so on.

Smart technology

Having smart technology on this purifier means you save more energy. When pollutants like pet dander and pollen are detected, the purifier fan will adjust itself. When the Coway Mighty has been running for 30 minutes without sensing any pollution, the fan automatically shuts off so it isn’t running continuously and not doing anything. This isn’t something you would be able to judge for yourself, so it is especially useful.

HEPA efficiency

Having the HEPA filter on the Coway AP-1512HH is vital to its efficiency. HEPA is able to effectively remove 99.97% of allergens so the air quality of your home is drastically improved. The HEPA is included in the Coway’s four-stage filtration system for thorough freshening.

Air quality and filter change indicators

Knowing what’s going in with the purifier is important in order to feel in control of your air quality. The air quality indicator on the Coway uses particle sensor technology, and changes color based on the air, so you always know what kind of air you’re dealing with. The other indicator is for the filter. It’s important to change the carbon filter every 6 months and the HEPA filter once a year, so the Coway Mighty will light up to let you know when it’s time for a change. You don’t have to keep track of the time yourself or worry that your filters aren’t doing their job well before they’re past their prime.


Great for health

The Coway Mighty air purifier is great for promoting a healthy living environment. With the HEPA, dangerous allergens and pollutants are nearly all eliminated, so if you suffer from allergies, you’ll feel much better. The Coway also comes with an Ionizer mode. This ionizer attracts positively-charged particles using negative ions, so like a magnet, the purifier’s ions pull dust, pollen, smoke, and so on into the filters where they are eradicated.

Very quiet

Another positive to the Coway is that it is relatively quiet. It doesn’t make noise much louder than a fan on its highest setting, so most of the time you won’t even know it’s there. You can have it any room without worrying about disturbing anyone.


The Coway is a lot smaller than a lot of other air purifiers out there. It weighs about 12 pounds, and can easily sit on top of a bedroom dresser. It is black and stylish, so it doesn’t dominate a room and distract from the rest of your decor.


Doesn’t have great odor control

The main weakness with the Coway Mighty is that it doesn’t control odors very well. Though it has a special odor reduction setting, it’s not especially effective. If you’re looking for a purifier that will help with pet odors, you’ll probably be disappointed. However, if odor is not a primary concern, the Coway Mighty is still extremely effective at removing pollutants.

Overall Review

Compact, stylish, and effective, the Coway Mighty air purifier uses smart technology and pollutant-killing HEPA filtration to radically improve the air quality in your home. If you suffer from allergies or lung conditions like asthma, the Coway will clear up nearly 100% of the little particles that trigger your symptoms.
