Coway Airmega 400 Design, Size, and Placement

The Coway AirMega 400 HEPA Air Purifier comes in a few different colors you can pick from, including silver/graphite and white.

This unit is just 23 inches tall and 15 inches in depth and width, which means it will need a bit of space, but it won’t take over the entire area.

It weighs some 25 pounds, which isn’t something you want to carry around, so make sure you have the right space for it.

The Coway Airmega 400 boasts a modern and minimalist design, suitable for various interior settings. Its compact dimensions (insert dimensions if available) ensure it doesn’t take up much space while delivering powerful air purification. The build quality is robust, featuring durable materials that enhance longevity and performance.

How it Works and Sources of Indoor Pollution it Destroys

Coway Airmega 400 has three different automatic operation settings that you can choose from that let it decide what it should do. These include:

• Automatic speed of fans – The machine regularly monitors the air quality and based on the results; it can change the speed that the fans are running for the conditions in the room.
• Sleep mode – If the room is dark and there has been no change in the air quality for some 3 minutes, the machine will automatically go into sleep mode.
• Eco mode – This mode is based on the air quality, and if it stays at a reasonable level for around 10 minutes, the machine will automatically turn itself off. When it notices that the air level changes, it will turn itself back on and automatically start cleaning the air again.

These are just a few main ways this specific air purifier cleans the air. It ensures that the air quality is the best for a certain amount of time before it shuts itself off to save electricity. This one is perfect for removing a few different indoor types of pollution, including:

• Smoke
• Dust
• Smells
• Chemicals

Coway Airmega 400 is ideal for those with asthma or other allergies as it cleans the air to keep one healthy.

Coway Airmega 400 Noise Level

Coway Airmega 400 is one of the noisier ones on the market, with a sound of 55dB when the fan is on, but not so much otherwise.

However, if you don’t have the fans on, it is around 39 dB, and the lowest level it has is 22dB, which is quieter than any normal fan or even a computer.

The only way you would determine that the system is running is to feel the breeze as it comes from the device itself. 

Coway Airmega 400 Coverage, CADR, and CFM

It has a CFM of 410 and 350 for the CADR levels for dust, smoke, and pollen.

Coway Airmega 400 cleans 624 square feet of large spaces every 12 minutes or 5 times per hour. That’s more than 90% of air purifiers on the market can handle.

In my opinion, there are only a few real competitors – AirDoctor 5000, which handles a massive 868 square feet large area, and AirDog X8, which handles 600 square feet.

You might also check Airpura C600 and IQAir HealthPro Plus Air Purifier, but they lack features, are noisy, consume more energy, and are pricey.

Coway Airmega 400 can be an expensive air purifier for maintenance due to the filters that should be replaced yearly.

There are two filters, which will cost you around $200; you need to ensure that they are being replaced to keep their activated carbon and HEPA components working to the best of their ability.
