If you\u2019re in the market for the Best Air Purifier, the next step is purpose. Is it a small room purifier or the best large room air purifier? If you leaned towards the latter, we suggest the Coway Airmega 200M. It\u2019s small, compact, and has a 4-stage filtration system as opposed to three or two for improved performance and efficient indoor air purification.\r\n\r\nWhy We Like It - Coway Airmega 200M\r\nThe Coway Airmega 200M pushes ahead of other air purifiers by introducing a fourth filtration system, as opposed to three or two and a half. It\u2019s also small, compact, and easy to move.\r\n\r\nPower & Speed\r\nOn the Coway Airmega 200M is three different speed settings, one less than the Coway Airmega 400, but is still average in terms of levels. On the highest setting, you can expect a CFM rating of nearly 250. Unfortunately, it isn\u2019t Energy Star certified; and despite being of smaller design, it can use upwards of 80 watts.\r\nEfficiency\r\nTo put its power and speed into perspective, it\u2019s more than capable of improving indoor air quality for rooms no bigger than 360 square feet. That\u2019s more on the smaller size, which is fine if that\u2019s what you need, but still twice as much as the Levoit Core 300. On the other hand, the Airmega 200M cycles out air in your room every 15 minutes.\r\nVersatility\r\nNot entirely unique, but still great is the Coway Airmega 200M\u2019s 4-stage filtration system. Its pre filter has no problem grabbing large particles in the air (human and pet hair or even mold). Harmful gases have to contend with the activated carbon filter, who fail and are trapped and scrubbed of odor. Afterwards, the True HEPA filter will tackle allergens, pollen, fungi, and even virus particles as small as 0.3 microns (99.97% efficiency).\r\nDurability\r\nRather than be short and wide bits of plastic, the Coway Airmega 200M is slender, yet wide. It measures 9.6 x 16.8 x 18.3 inches, which does add some depth to its base, but could lead to knocking it over if not careful. After all, it\u2019s just 12.3 lbs.\r\nValue\r\nConsidering how affordable the Coway Airmega 200M is, especially compared to Alen Breathesmart Classic Large Room Air Purifier, it\u2019s right on track for having excellent value. It has the performance and design to warrant its price. You\u2019ll pay just an itty bitty more on energy, but it\u2019s peanuts compared to other air purifiers in this bracket.\r\nCoway Airmega 200M Wrap Up\r\nCoway did it again with the Coway Airmega 200M: an affordable, yet strong companion for purifying the air around you. And it\u2019s in the perfect position for improving air for your living room or bedroom, especially with its improved filtration system and Auto Mode. Don\u2019t let the lack of an Energy Star certification turn you away.
