Coway Airmega 50 Evaluate: Efficient and Reasonably priced (2025)

I’ve been on the air high quality beat for some time right here at WIRED, and I usually make the argument that buyers ought to go massive in relation to indoor air, as a bigger fan and filter floor space produce a quieter and extra highly effective air air purifier. Nevertheless, if ever there have been a fun-sized air air purifier that punches above its weight (all 5 kilos of it), it’s the most recent from air powerhouse Coway, the Airmega 50.

Standing simply over a foot tall, the Airmega 50 was simply launched in June and is an addition to the rising tabletop air air purifier area—a mini-me to the model’s Airmega 100. The Airmega 50 has most of the options of Coway’s bigger and dearer fashions, and at slightly below $80, it’s one of many least expensive Coway air purifiers thus far. I perceive the will to have an easy-to-carry tabletop-sized air air purifier, however can they actually clear the air successfully? For a lot of, these proplike purifiers create a idiot’s paradise. I examined the Airmega 50 with an air high quality monitor to see if it was as much as the job of purifying the air in my 100-square-foot bed room.

Small Packages

When buying a tiny-footprint air cleansing equipment, one must know the realm of the room it will likely be cleansing. Which means you are measuring the size and multiplying it by the width. Coway claims the Airmega 50 can alternate the air in a 500-square-foot room as soon as an hour. In line with the CDC, customers ought to intention for 5 or extra air modifications per hour (ACH). Following the CDC suggestion, the Airmega can successfully clear the air in a 100-square-foot area 5 instances an hour. That is about half the dimensions of the common school dorm room. Dwelling in New York Metropolis, I’ve seen nurseries, residence and company places of work, Harry Potter under-the-stairs-sized bedrooms, and walk-in closets changed into dens which can be round 100 sq. ft. If any of these descriptions match areas in your house or at work, then the Airmega 50 is an affordable answer to mitigate unhealthy air.

Airmega 50’s cylindrical design pulls in air from all sides. To realize the best air alternate per hour, small air purifiers crank the fan. And as a rule, smaller doesn’t imply quieter, although within the case of the Airmega 50, its highest setting got here in at round 60 decibels on my Toptes Sound Stage Meter, just like the hum of a fridge. And whereas most white-noise machines are someplace between 50 and 70 decibels, I discovered the Airmega 50’s highest setting to be too loud for nighttime. Its sleep mode turns off its indicator gentle and reduces the fan to its lowest and quietest setting. An air air purifier’s sleep mode is when the air purifier turns into a much less efficient model of itself, and the Airmega 50 is not any exception. Customers have the choice to show off the indicator lights and activate the nightlight mode. I want the lights off, however when my youngsters had been little, I might have utilized the evening gentle mode.

The Airmega 50 has most of the options that make Coway air purifiers a long-term WIRED favourite. For these with pets and younger kids, the management panel lock is a should. There’s additionally a much-appreciated filter alternative indicator gentle, plus an eight-month filter life expectancy. Not like among the bigger Coway fashions which have quite a lot of bespoke air filters, together with ones particularly made for pet homeowners, allergy victims, and intense smoke, the Airmega 50 presently has solely one possibility, for $30.
