Air purifiers employ various technologies to filter the air around you, and they are a lifesaver for those who suffer from allergies or asthma or have weak immune systems. These three air puffers by Coway offer powerful purification in a compact, clean package.

Coway AP-0512NH

The Coway AP-0512NH is equipped with two filters and a variable-speed fan. It boasts a sound therapy system that includes peaceful songs and noises, all of which have adjustable volumes. This dual-purpose air purifier is ideal for a nursery.

Coway also makes a larger air purifier that covers more square footage. The AP-1512HH contains three filters and an ionizer. It has a timer and a power-saving mode. If you opt to use it, auto mode changes the fan speed for you, kicking it up when the air quality is poor and lower it when it’s good.

If a small, boxy air purifier doesn’t suit your taste, Coway has a tower purifier. The Coway AP-1216L is almost equivalent in coverage and purification power as the AP-1512HH. Like the previously mentioned air purifier, this model has a timer, an ionizer and a multi-speed fan. Plus, you can shut off the indicators if the lights disturb your sleep.

Size and Coverage

The Coway AP-1512HH
For those who have a sophisticated taste, the black finish and gray ring on his air purifier will speak to them. Perfect for the average-size bedroom, this air purifier is efficient in 361-square-foot areas. It has dimensions of 16.8 inches in length, 18.3 inches in width and 9.6 inches in depth with an average CADR of 240.

The Coway AP-1216L
Instead of a squared body, the Coway AP-1216L is a 32.7-inch-tall tower. Its glossy white finish works well in almost any room. With a width and depth of 10.5 inches and 10.7 inches, it doesn’t hog a lot of space.

The AP-1216L is rated for rooms as large as 330 square feet, and its average CADR for smoke, pollen and dust is 237.

Conclusion: Each Coway air purifier is larger than the next with the AP-0512NH being the smallest of all three. This purifier and the AP-1512HH are square in shape while the AP-1216L is a tower-style purifier. Although the AP-0512NH’s CADR is half that of the other two models, this is to be expected due to its small size.

Filtration and Fan Speed

The Coway AP-0512NH
Inside of the Coway AP-0512NH air purifier, there are two filters. One is a true-HEPA filter that’s designed to trap 99.97 percent of allergens.

The other filter is a carbon filter, which knocks out foul odors. When it’s time to replace the filters, an indicator light glows. If you want to lower the sound of the fan or kick up the purification, you can adjust the fan to one of three speeds.

The Coway AP-1512HH
Coway added an extra filter to the AP-1512HH. In addition to a true-HEPA and an activated filter, this air purifier contains a protective pre-filter. This filter captures large particles that clog fine-allergen filters.

Like the AP-0215NH, the HH version has a filter-change indicator light. This air purifier also has a whisper-quiet triple-speed fan. If you don’t want to manually adjust the fan speed, you can choose auto mode. There is also an energy-friendly eco mode.

The Coway AP-1216L
With this air purifier, you get three filters too – a pre-filter, a carbon filter and a true-HEPA filter. If you wash the pre-filter when it’s dirty, you can reuse it. A color-coded air-quality indicator gives you a general idea of the surrounding air’s health.

The fan can be set to low, medium or high speed. Plus, there is an auto-speed option with a max decibel level of 52.

Conclusion: Every air purifier has a three-speed fan. The AP-1512HH and the AP-1216L have an auto mode, and the AP-1512HH purifier also has an eco mode.

All the air purifiers are quiet at any speed. Even though the two largest purifiers come with three filters, the smallest model is equipped with the two main filters every high-quality air purifier should have.
