The Coway AP-1512HH is one of the best filters for small rooms available. Despite its small size, this air purifier can filter 268 cubic feet of air per minute. You'll even notice a difference in medium and larger rooms, although it loses much of its filtration efficiency in larger spaces. The Coway uses a four-stage filtration process. The washable prefilter captures large particles like hair. The carbon filter removes offensive odors and gases. The True HEPA filter captures allergens such as dust and pollen. Finally, the optional Vital Ion filter charges outgoing air for easier capture on the next pass.

The Coway's clean air delivery rate is impressive. It does a great job with dust and pollen, and it is a great tool for those who struggle with allergies. Its smoke and odor rating is lower than we would like, but it is still far better than many other small-room air purifiers.

Our favorite aspect of the Coway AP-1512HH is its low noise level. At its maximum setting, it can be a little overbearing, but at the lower settings, you'll hardly notice it in your room.

The Coway's four-stage filtration process gives you an excellent level of air purification. However, if you have sensitive airways or breathing-related issues, you should avoid using the Vital Ion feature. All ionizers generate a small amount of ozone, which can exacerbate conditions like asthma. Also, some studies have shown that charged particles can damage otherwise healthy lungs.

Unfortunately, without the Vital Ion filtration, the Coway loses much of its air-purifying capabilities.

The Coway is Energy Star verified and uses less than 78 watts at its highest settings. Some of the other large air purifiers we reviewed require more than 60 watts to run on their lowest settings. The air purifier's lowest setting only uses 5 watts of power, so you won't see much of an impact on your energy bills if you use it to filter the air in your home.

One of the Coway's best features is its air-quality sensor. The air purifier monitors indoor pollutants and adjusts the fan speed to maximize its filtration capabilities. If you decide to use the Vital Ion filtration feature, you can set an operation timer to control its operation. This way, you can control the level of electromagnetically charged particles in your room. The timer runs for one, four or eight hours, and then the unit goes into standby mode.

The Coway is one of the few air purifiers we reviewed with an eco mode. If the air-quality sensor does not detect any pollutants for 30 minutes, the filter is automatically set to sleep mode. Finally, the air-quality sensor provides a color-coded guide for the level of indoor pollutants in a room.

Coway could use some improvements in its customer support offerings. In the company's favor, they do have a three-year warranty, and Coway's support representatives are available by phone and email. However, the company's website offers few self-help options. You can download a new owner's manual, but the site lacks a FAQs section and knowledgebase. In fact, Coway's website even lacks a dedicated support page.
