Coway Airmega AP-1512HH(W) true HEPA purifier reviews

One helpful element is the air quality indicator light. The Airmega measures the level of air pollution by sucking in particles, pollutants, and pollen. If the light is blue, your air quality is OK; if it is orange, it is somewhat worse; and if it is red, your air quality is bad. For nighttime use, you can turn off the light by holding down the ioniser button for three seconds. When in auto mode, the Airmega AP-1512HH will automatically modify its fan speed in response to the air quality. Get details in Coway Airmega AP-1512HH(W) true HEPA purifier reviews.

It is one of the most energy-efficient versions we tested, consuming only 0.01 kWh of electricity every hour of operation. In most houses, this comes out to around $5.26 annually. But replacing filters are kind of expensive; we usually found them for $60, though occasionally there are less expensive options.

It’s a good thing that the 16.8 x 18.3 x 9.6-inch Airmega AP-1512HHS looks more like a sleek subwoofer than an air purifier, with to its rounded corners, glossy plastic surface, and unique-looking ring in the front. The 12.3-pound appliance can be moved and picked up thanks to its incorporated handle.

It also feels more at home in a hotel or office block than in a contemporary home due to its extremely plastic surface.The body resembles an old iPod Shuffle greatly. It is just a little box with a circular opening in front to let air in and a fan on top to shoot it back out.


You may set a one, four, or eight-hour off timer, switch between fan speeds, and turn on and off the ioniser using a number of controls on top of the device. It has four fan settings: eco, high, medium, and low. Furthermore, it has an integrated air quality metre, which allows you to programme the fan speed to run automatically and adjust the purifier’s intensity based on the ambient air quality.


The Coway AP-1512HH has a GreenHEPATM filter, which the company claims can remove up to 99.97% of dangerous airborne particles, including tiny dust particles and tobacco smoke. Additionally, it has built-in sensors that monitor the air while the purifier is operating, providing a real-time air quality indicator light (blue for good, red for poor). In addition, the purifier has a pre-filter to catch bigger particles and a deodorization filter to get rid of gases and smells.

CADR rating

The Coway Airmega AP-1512HH advertises a recommended room size of 361 square feet after achieving CADR ratings of 247.5, 232.3, and 241.3 for smoke, dust, and pollen, respectively. Considering its little size, this is a solid grade.

Variable speed

There are five fan speed settings available for the Coway Airmega AP-1512HH, including an eco and auto mode. There’s also a timer you can use if you want your air purifier to turn off when you leave. On top of all of this, there’s an ioniser option with a separate button that helps enhance the quality of the air it draws in. It spreads negative ions, which cling to impurities and facilitate the filtering process of the machine.


The Coway Airmega AP-1512HH is very simple to set up right out of the box. To access the two other filters (the charcoal and HEPA filter) beneath the pre-filter, you must first open the front hatch, take off the strips keeping it in place, then remove the plastic bags containing the filters. Simply make sure to put things back in the correct order; otherwise, they won’t fit.The beeps and boops clearly indicate the reaction, and the controls are easy to use. It should be easy to store out of sight if necessary because it is so little and simple to assemble.

Coway Airmega AP-1512HH(W) true HEPA purifier Performance reviews

In less than thirty minutes, the Airmega 1512HH eliminated 99.32% of the airborne particles in our unclean air testing environment. During our testing, we saw that this was one of the fastest cleaning times. It got one of the finest reduction rates of all our purifiers, 99.84%, after one hour.

Our tests were first conducted at the highest level, which produced a decibel reading of less than 50. That was the second-highest setting, level 2. It operated at about 42 dB, which is comparable to a quiet library. Then, using the more advanced level 3 setting—a potent but noisy 57 decibels—we repeated the same test.

The ambient air quality came first. When operating at level 2 fan speed, the Coway AP-1512HH captured 72.4% of particles smaller than 0.3 microns and 72.7% of particles smaller than 2.5 microns, according to data collected using an air particle counter prior to, during, and following the test. This improved, we discovered, with the purifier eliminating 92.8 of particles smaller than 2.5 microns and 89.9% of particles smaller than 0.3 microns at the highest fan speed.


The Coway Airmega AP-1512HH measured 36.8 decibels at its lowest setting and nearly 58 dB at its peak. Although it’s not overly irritating or distracting, it does have some kick. At least you are aware that its remarkable CADR is being achieved with all that noise.
