Coway AP-1512HH Mighty and Coway Airmega 200M are two of the best air purifiers on the market. Both are effective, efficient, and affordable. The Coway AP-1512HH Mighty is a great choice for medium-sized rooms, while the Coway Airmega 200M has a different look but offers the same great performance. When it comes to air purification, ion filtration technology is not a major advantage, but it also does not produce significant ozone, as tested by the California EPA.
The Blueair Blue Pure 411 is a simple and straightforward purifier with a smart design and a good investment. It offers particulate and carbon filtration that works well in a 160 square foot room, making it the best overall air purifier for small rooms. The Sharp air purifier does not offer as much cleaning power at almost double the price. If you have the money and want a super-powered air purifier, or if you need to cover your entire house with one purifier per room, then the Coway Airmega 400 is the best option.
It costs a bit more but provides 1,560 square foot air cleaning coverage. When looking for an air purifier, it's important to consider power for price (i.e., the higher the CADR and the lower the price, the better). Additionally, look at additional cleaning modes, controls, design, and noise level. The best air purifier should look elegant enough to fit modern decor, work as desired with minimal manipulation, and clean the air thoroughly and quietly.
The Levoit LV-H134 covers up to 710 square feet with a CADR of 312 CFM and can generate noise in the range of 18-45 dB. The Coway 1512 has a coverage area of 360 m2. Ft., with a CADR of 141 CFM and noise range of 20-54 dB. The 300S uses a HEPA filter with an activated carbon layer that is easy to replace as needed. Most of the best air purifiers on the list contain something called a high-efficiency particulate absorption (HEPA) filter.
HEPA filters can remove 99.97% of air pollutants 0.3 microns in size, making them ideal for removing most indoor air pollutants. The most effective air purifiers will remove different types of particles from the air but can never get it 100% “pure”. An air purifier works by having a fan that draws air inside the house into filters that remove impurities before returning clean air to the room. However, it is impossible to remove all particles that can live on walls, carpets, bedding and hard surfaces. The Levoit 400S performed best in removing airborne particles in our home tests, capturing at least 99.5% and up to 100% of particles during testing.
The Coway-AP-1512HH air cleaner also benefits from a built-in particle sensor that shows a blue light when the air is clean. After careful testing and consideration, these are the best air purifier options according to our research: Coway AP-1512HH Mighty, Coway Airmega 200M, Blueair Blue Pure 411, Sharp Air Purifier, Coway Airmega 400, Levoit LV-H134 and Levoit 400S. Any of these air purifiers should improve indoor air quality, filter out smoke and particles in the air, and provide fresh air.
