The Coway Airmega 300 is one of those air purifiers that guarantee that your indoor air quality stays relatively high, and with a room coverage that stands at 1,256 sq ft, it’s probably the best air purifier for anyone who has a large living space. At around $420, most people would consider the air purifier as relatively expensive, but if you value ease of use, then some of its smart features might be well worth the extra bucks. Could it be the best smart air purifier for you? Let’s find out.

Why We Like It – Coway Airmega 300

Coway air purifiers are known for their exquisite build quality, and the Coway Airmega 300 isn’t anything different. It’s backed by an impressive 5 year warranty, and despite the lack of WiFi connectivity, it still remains a reliable unit that is sure to offer long lasting service.

Pros
  • Efficient air quality monitoring & filter status indicator
  • Energy Star Certified
  • Impressive 5 Year Warranty
Cons
  • No WiFi connectivity for app support

Power/Speed

You’ll get up to 5 fan speed choices with the Coway Airmega air purifier, so you’ll have direct control over how exactly the unit does it’s job. Alternatively, you’ll also have the option to switch it into smart mode, and have it regulate the fan speed based on your room’s real time air quality. The unit also boasts of a 3 stage filtration system, where it’s got a washable pre filter that traps larger dust particles, and a set of Max2 filters that consists of a True HEPA filter that catches 99% of air particles, and an activated carbon filter gets rid of bad odours. This 3 stage filtration system is not as detailed as the one that you’ll find on the Rabbit Air Minusa2 Air Purifier, but then again, you’ll have to pay a bit more to enjoy the Minusa2’s elaborate process.

Efficiency

With a power consumption level that averages 56 watts, the Airmega 300 is pretty energy efficient, so you shouldn’t expect it to ramp up your electricity bill. In fact, just like the Airmega 400S, the unit boasts of an Energy Star certification, making it a perfect option for anyone that might want to keep tabs on their energy costs. The smart air purifier has also got a timer that allows you to schedule it for 1, 2, 4, or 8 hours, as well as a sleep mode that you can switch it to in the event that you need it quiet enough for functioning at night.

Versatility

On board the Airmega 300, there’s a pollution sensor that allows for air quality monitoring, and through the colors on its LED ring, you’ll also be able to monitor air changes, and know how clean or dirty the air in your room is. Unfortunately, the Airmega 300 does not have WiFi support, so by extension, it isn’t really app enabled. On the positive side though, the unit does have a filter indicator on its control panel, so you will be able to know whenever filter replacement for both the Green True HEPA air filter and the activated carbon filter is due.

Durability

Coway Airmega air purifiers have a solid reputation when it comes to reliability, and this is why almost all of them are backed by a 5 year warranty policy. You will have to replace the True HEPA filter maybe once or twice per year, but since its pre filters are washable, they’re very easy to maintain.

Value

The Max2 filter set that you’ll find with most Coway air purifiers combines Green True HEPA filter technology with an activated carbon filter, making the whole filter replacement process a lot more convenient. The Green True HEPA air filter is also quite different from the HEPA filter you’ll find on the Bissell Air Purifier, as it is made out of environmentally friendly materials, and has a unique property that destroys protein on the surface of virus and bacteria.

Coway Airmega 300 Wrap Up

Going by the large number of customer reviews that have been left by users of the Airmega 300, it’s pretty easy to see how reliable it is, as well as how efficient it is at its functioning. If you’re looking for a unit that is easy to use and suitable for a large room, it should be your pick.
