About the Coway Airmega Aim

The Coway Airmega Aim is an air purifier that blows cold air in many different directions.

  • Area coverage: 246 square feet
  • Dimensions: 18 x 20 x 8 inches
  • Weight: 7.5 lbs
  • Color options: White, gray
  • Maximum noise level: 56 decibels

The Coway Airmega Aim features a rounded-edged filter on a double-axis swivel pedestal, and the sides are perforated mesh. It is white with gray accents—a neutral color palette that fits in with many homes.

The base of this Coway air purifier features a digital screen that displays air quality insights and information about the current mode. This screen tells you when to change the filter and dims automatically when not in use.

In addition to the controls on the base, the filter is controllable via a remote. It can also run on a timer.

The Airmega Aim includes three stages of filtration: a prefilter for larger particles, a HEPA filter, and a deodorizing filter. Replacement filters are available on the Coway website.

The Aim contrasts with the large, stylish Airmega Icon. The Aim fills a very different niche, circulating clean air around rooms up to 246 square feet and cooling them.

What we like

The powerful air circulation adds to performance

The Coway Airmega Aim is great for small spaces.

Air purifiers perform best in an open space. But the powerful oscillating fan of the Airmega Aim overcomes this problem, distributing filtered air as widely as possible.

The fan has a multi-angle vertical that tilts up to 90 degrees, and auto oscillates up to 80 degrees.

The Aim delivers clean air exactly where you need it

The adjustable fan angle allows you to direct the filtered airflow to where you need it the most.

The Airmega Aim is perfect for targeting specific locations around the home, like your bedroom or home office, because the adjustable fan angle allows you to direct the filtered airflow to where you need it the most.

The Aim provides direct, clean indoor air wherever you need it.

This Coway air purifier has an oscillating fan to keep you cool

The fan is powerful enough to fulfill the role of a conventional oscillating fan.

The multi-functional design means you get the benefits of air purification and cooling, which is great news during the heat of summer.

The Airmega Aim is easy to use

The Aim comes with an air quality sensor that constantly monitors the air quality in your home automatically, adjusting the fan speed and airflow to match pollution levels.

Auto mode frees you up from adjusting the settings yourself. It also saves energy, ensuring the fan will only run as fast as necessary.

This Coway air purifier does not work with a compatible smartphone app, like our favorite, the Blueair DustMagnet 5410i, which lets you monitor filter levels, runtime, and more, does. However, features like automatic mode, timer functionality, and remote control make up for the missed convenience of a smartphone app.

The filter changes are also incredibly straightforward. The prefilter, HEPA particle filter, and carbon chemical filter are in a single filter unit.

A filter life indicator that alerts you when a replacement is needed. To replace the filter, twist off the base and insert the replacement.

What we don’t like

It’s noisier than some conventional air purifiers

The oscillating fan design is fairly noisy because the fan blades and motor are more exposed than in a conventional air purifier.

On the low setting, the Coway Aim fan operates at 38 decibels. This is a long way from being annoyingly loud during the day. However, it might be too loud for some to sleep with.

Purifying performance is for small spaces only

The particle and VOC filtering are limited compared to larger units, so use it in an appropriately sized space to achieve maximum performance.

It does offer relatively low clean air delivery rates that read at 66 for smoke and 88 for pollen and is best for use in single rooms—not open floor plans.

This Coway air purifier doesn’t have washable prefilters (but you can vacuum them)

The Airmega Aim does not have a washable prefilter, which is an eco-friendlier option than a disposable one. However, you can vacuum the filter.

While the washability isn't a dealbreaker, other air purifiers, like the Winix 5500-2, include washable prefilters that pick up larger particles like cat hair and dust clumps.

Should you buy the Coway Airmega Aim?

Yes, this filter doubles as a fan without sacrificing filtration quality

The Coway Airmega Aim includes three stages of filtration to improve indoor air quality.

If you’re looking for an air purifier that works well in a smaller space and also doubles as a fan, the Aim is an excellent choice.

The oscillating fan function ensures a clean, cool airflow. This Coway air purifier is great for apartments, studios, and home offices.

If you’re looking for a bedroom air purifier, some users may find the fan too noisy, though others might enjoy it as white noise.

But overall, this two-in-one HEPA filter air purifier and oscillating fan offers plenty of value, combining two technologies into one unit for incredible performance.
