The Coway AP-1512HH is a wonderfully effective and efficient device. It’s quiet, energy efficient, and at times seems psychic; it can automatically detect pollutants and adjust its work pace accordingly.

It’s perfect for medium-large bedrooms and small living rooms, but can work slowly when tackling larger living rooms (albeit still effectively). It specializes in eliminating odors and other particles, but can sometimes struggle with large amounts of dust.

  • Extremely “intelligent”
  • Handles odors with ease
  • Energy efficient
  • Smart, sleek design

  • For the price, it should deal with dust better
  • Can work slowly when facing large rooms (over 400 square feet)


Today we’re talking about one of the highest rated air purifiers on the market: the Coway AP-1512HH. Does it live up to the hype? Let’s dive in.

Uncanny Intelligence

The AP-1512HH has several really, really nifty features. First, it has an air quality indicator. The device has the ability to monitor particles in the air, and it can adjust its airflow to deal with different levels of air quality.

It has an Eco setting, where the device self-starts when it detects pollutant levels above a certain threshold (set by you), and turns itself off when optimal air quality levels are achieved (also set by you).

The unit even changes colors depending on the space’s current air quality – which is a pretty neat way to easily gauge whether you need to be running the device or not. A light will also pop on when it’s time to change the device’s filter.

The AP-1512HH is Energy Star® certified and uses 79 W (0.5 when on standby). For a device that boasts a CADR rating of 210, that level of energy efficiency is exceptional.


The unit covers 326 square feet, and can produce quite an airflow. It features 3 layers of filters: a washable pre-filter (for dust and hair), a carbon filter (for odors), and a HEPA filter for smaller particles. When placed in a medium-large bedroom, it works with wonderful effectiveness and efficiency.

The device’s performance lags a bit when put in a large living room – it’s still effective as eliminating odors, allergens and dust, but it works slower. In this case, I think the manufacturer is right on the money with its coverage estimate of 326 square feet. Overall, AP-1512HH is a very powerful device.

It’s quiet, too. It achieves true “whisper”-level quiet on lower settings, but you’ll be able to sleep comfortably even when the unit is operating on its highest setting (at its loudest, it still doesn’t exceed 50dB).


I want to tackle one big and important concern. The AP-1512HH utilized an ionizer, and one of the most common questions I hear regarding ionizing air purifiers is: does the device emit ozone?

The good news is the California EPA Air Resources Board asked the same question. They tested this unit, and safely certified it; according to the tests, the AP-1512HH generates ozone levels of between zero and 0.050 parts per million – in other words, very little.

The unit looks compact, and it is relatively small, but it takes up more space than you think. Additionally, it weighs 12 pounds – that’s what happens when you pack so much into such a small device.


8.3 Total Score

The Coway AP-1512HH is effective, quiet and extremely intelligent. It handles odors and particulates with ease, and the device is Energy Star certified. The biggest knocks on the unit are the way it manages dust, and the fact that it slows down when facing rooms over 400 square feet.
