Our Rating


Air purifiers may seem like simple products initially, and that is true in some sense. After all, they are designed to clean the air within a space, and nothing more. Still, a lot of work goes on within an air purifier to make this process actually work, and not all products are truly up for the challenge — at least when it comes to being thorough.

That’s where the Coway AP-1512HH Mighty Air Purifier comes in. While certainly not the most complicated or expensive air purifier out there, this product outperforms many models twice its cost, and still maintains an affordable price point.

But those aren’t the only benefits to be gained. The Mighty Air Purifier is convenient in every way, and avoids nearly every shortfall that plagues more inferior air purifiers.

About The Product

The Coway AP-1512HH Mighty Air Purifier is equipped to handle even the largest rooms, and remains effective up to 361 square feet. This is made possible from a 77 Watt motor that provides a high amount of power, even though it does not seem like it when running (that’s a good thing.)

So, whether you use this in a bedroom, or a larger space like a living room, it will have no trouble providing purified air any hour of the day.

The main advantage with the Mighty Air Purifier resides in its detailed 4-step cleaning process, which starts out filtering larger particles, and dwindles down to the most microscopic particles before sending the filtered air back out into the space.

The purification process begins with the outermost filter, which is a washable pre-filter. This filter catches things like pet hair and dust, and lasts for an extended amount of time when washed as directed.

From there, the air moves through a smaller odor filter that eliminates any unnatural smells from the surrounding environment. This can include mld-like odors, the ingrained pet odors that can linger otherwise, and even cooking odors from burnt food. 

The air then travels through a True HEPA filter that captures the smallest particles, including pollen, pet dander, household dust, and even smoking odors. The filter will catch particles as small as 0.3 microns, 99.97% of the time. If by chance any particles escape the filter, they’ll be caught the second time through regardless.

Finally, an optional ionizer mode can be used to boost purification even more. This setting will enhance the other filter stages, and also infuse negative ions into the air to create a more balanced environment.

As for fan speeds, you get three distinct choices to set manually if desired. The first two are almost completely silent, with the third being barely audible, with a pleasing white noise sound that is easy to deal with when sleeping.

While the three speeds can be manually set, the Mighty Air Purifier comes with an automatic setting that will actually perform a diagnostic on the room’s air quality, and then assign the best speed to deal with it.

Once a satisfactory air quality has been reached, the unit will shut off after 30 minutes, and enter Eco mode, where it will periodically test the air again to determine if it needs to come back on. For those who like to stay informed of their air quality, a sensor light is located on the unit, and changes color depending on the air quality in that moment. 

There’s also an indicator light that will give you statuses for the unit, and tell you when it’s time to clean or change a filter. This not only ensures peak performance at all times, it also adds to the overall longevity and energy efficiency of the unit.

What Others Say

Practically every feature and aspect of the Mighty Air Purifier is worth highlighting. However, the Eco mode is certainly one of the best.

The ability to leave the machine on and let it determine when to actually operate is not only convenient, but also drastically reduces the amount of energy it consumes. The indicator lights are very helpful as well, and serve to keep you informed of air quality at all times.

The 4-part filter system is easy to manage when it’s time to wash or change a filter, and the overall design of the filter system is incredibly thorough and effective, eliminating every last particle or smell that may be hindering your air quality.

Finally, the actual noise amount is exceptional. Many air purifiers work very well, but fail when it comes to noise amount, and can sometimes even disturb sleep for certain users. Not so with the Mighty Air Purifier. As mentioned earlier, it truly avoids all the common issues that plague other products.

There’s really no glaring faults with this air purifier whatsoever. That being said, it wouldn’t surprise us if the indicator lights are too bright for some when used in a dark room at night. It would be nice to see Coway add a night mode in the future that dims any lights on the unit, to better match the already low fan noise.

Buying Advice

With all of these benefits, it’s easy to see why this unit routinely places at the top of air purifier reviews, and is one of the most popular air purifiers on Amazon. Just be sure to use it in the appropriate-sized space for maximum effect, and be aware that it comes with a generous 3-year warranty for the motor and all electronic parts.

Final Verdict

The Coway AP-1512HH Mighty Air Purifier is simply one of the best air purifiers on the market, regardless of size or type. It focuses on all the right aspects: filter system, settings, fan noise, and energy efficiency.

On top of that, it has a very sleek and modern look that won’t hog up the space it’s used in. If you’re looking for the best air purifier under $200, this is the one.
