Similarities: Coway Airmega 300 vs 400 surprised us!

similarities of coway airmega 300 and 400

Let’s first take a look at the similarities of Coway Airmega 300 vs. 400;

Filtration System

A standard 3-stage air filtration system has been put in place. Firstly, a washable Pre-Filter is a barrier to larger particles like pet hair and pollen. Fortunately, both devices are shipped with a TRUE HEPA filter.

Moving forward, you get two more filters. Uniquely, Coway has proven to be more advanced than it seems. A carbon and HEPA filter are combined into one single filter.

You might be thinking, what was the idea behind merging filters together? We have got positive news for you! Using two separate filters increases the overall cost of purifiers. So, the maintenance of these devices is cheaper this way.

Furthermore, a wide range of odors and VOCs (volatile organic compounds) are cleared through this filter, namely “Coway Airmega Max2”. It removes 99.97% of airborne particles. Also, particles as small as 0.3 microns are trapped.

Smart Auto Mode

We realize the importance of saving electricity and the bills coming with it! Did you know that the more the fan speed, the more electricity air purifiers consume? The question is, how do Coway Airmega 300 and Coway Airmega 400 reduce power usage?

An auto fan smart mode feature evaluates the room’s air quality and adjusts fan speed according to it. Bad quality increases fan speed, whereas a lower rate indicates better indoor air quality while saving energy!

Filter Replacement Indicator

How do you know whether those filters need changing? Voila, they got lights for it. Two lights come with both of our competitors—one for pre-filter, another for the Max2.

An indicator light glows up if the filters are clogged to the point that they cannot provide the usual efficiency. It would be best to replace them as soon as possible in this situation. So, it’s great peace of mind.

Smart Eco Mode

An uncommon feature found in these devices is an Eco mode. You won’t get to see unique features like it in other air purifier models in 2022.

How does this work? It monitors the air quality for 10 minutes. If it remains unchanged, the fan automatically shuts down. Energy wastage is mainly reduced, thanks to ‘Smart Eco Mode”.

LED Display

You are absolutely correct if you think Coway Airmega 300 vs 400 comes with many common features. Air quality monitoring is a common feature of both models.

Take a look at the front; you will see an LED ring. A pollution sensor has been embedded inside its body. It monitors air pollution levels and changes shades accordingly. We love its glow; we hope you would too!

Air Quality Monitoring

The air quality monitor helps you know how many dust particles, pollen, pet dander, smoke particles, and others are in the air. Also, the air quality sensor lets you know when the filter needs changing.

Both Air purifiers have an air quality monitoring feature that displays the air quality in real-time and uses an LED ring. The LED ring can change colors depending on the level of pollutants present in the air.

Timer

Finally, the last common feature in these most demanded models is a built-in timer. Do you want to schedule it to turn off at a specific time? If so, you get 3 timing options, 1, 4, and 8 hours in a single button.
