Coway 2-in-1 Air Purifier and White Noise Machine AP-0512NH Review

Coway offers the perfect solution to parents who are worried about the quality of air their babies breathe and the quality of sleep their babies get. This mini-machine is part air purifier and part white-noise maker. Even better, you can run the purifier and soothing sounds separately or together.

Coway 2-in-1 Air Purifier and White Noise Machine AP-0512NH Review

The 2-in-1 purifies the air with a multi-speed fan that covers over 150 square feet of space. With a high-efficiency particulate air filter, microscopic allergens won’t stay in the air long. This filter is covered by an activated carbon filter that eliminates foul odors.

While the air purifier does produce white noise, you also have a selection of nature sounds and lullabies from which to choose. You can easily adjust the volume via the touch-button control panel, which also alerts you when it’s time for a filter change.

Odor-Controlling Air Purification

Inside of the Coway 2-in-1 Air Purifier, there is a true-HEPA filter. This filter is able to trap 99.97 percent of allergens as small as 0.3 microns in diameter, including dust, pollen, and dander. As a bonus, Coway adds an activated carbon media to the filtration system, which knocks out unpleasant smells that stem from smoking, cooking and diaper changing. Together, the filters are so effective that they earned a CADR rating of 100+ in rooms up to 155 square feet.

With a lifespan of 12 months and 6 months, you won’t spend a lot of money per year replacing the HEPA filter and the carbon filter. When it’s time to change them, the purifier’s filter indicator illuminates, saving you the trouble of keeping track on a calendar. Since the front cover pops off quickly, replacing the filters is a breeze too.

Relaxing Sound Emissions

Coway didn’t just subjectively decide on the sounds to include. The company relied on science by consulting with medical experts to compile a collection of Sound Therapy sounds and songs that are designed to induce sleep.

For your baby, there are two lullabies – one by classical composer Franz Schubert and the other by romantic-era pianist Johannes Brahms.

If you want to play background noise instead of music, Coway has you covered. You can choose to listen to basic white noise. Alternatively, there are three nature sounds. One soundtrack is inspired by the waves of the ocean, the second one mimics the sound of soothing rainfall, and the third recreates the gentle noise made by chirping crickets.

Controls That Offer Customization

Although there are eight buttons on the control panel, they aren’t hard to navigate with illustrations and labels telling you what each touch button does.

On the left side, there is the power button, the filter reset button and two buttons for purification customization. You can set the fan to one of three speeds and the purifier’s timer for 1, 4 or 8 hours.

On the right side, there are four buttons that control the sound output of the air purifier.

The music note button allows you to cycle through the six sound options while the clock button sets a timer for 15, 30 or 60 minutes depending on the number of times you press it. Between these two buttons, there is a plus sign and a minus sign button, which adjusts the sound to one of five levels.

Fitting for Any Space

If you’re buying this air purifier as a gift for a baby-to-be and you don’t know the gender, don’t worry. The color scheme of the Coway 2-in-1 is suitable for a boy’s or a girl’s nursery with its solid-white housing and soft-green decorative ring.

The air purifier is also sized to fit on small dressers or nightstands. Measuring about 14 inches in width and height and approximately 8 inches in depth, you’ll find it a place for it even in cramped quarters. At 8.8 pounds, it’s not heavy, so you can relocate it with no trouble.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.

Best of the Best If you have a large space you want to remove irritants from, We recommend the Airmega 400S. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them. The 400S is designed to accommodate large room sizes.
