Thinking of buying an air purifier? You are hardly alone. As the pandemic strikes, with people spending more time inside their homes, the number of air purifiers in use around the world has increased. To date, there are around 21 million purifiers in residential spaces, up from around 5.97 million in 2015, according to Statista.

Two air purifiers that can handle a larger space – i.e. more than a single room – include the Coway Airmega 250 and the Aura Air. We’ve spent some time with the two, and here’s what we found in terms of comparison and where they differ. You can then choose the one that best suits your home and your needs.

The Aura Air is a square shaped purifier with rounded sides, and has a very unique placement: on the wall. We haven’t installed the unit yet when we got it this way, but the air purifier is meant to be anchored to the wall, and on its own, to properly clean the air in a space. . It’s almost architectural in design with a white front and softer gray sides – and there’s a power cord needed to operate it, which will meander along the wall to an outlet.

It’s also a smart device, which means you can extract the details the Aura Air collects from its app, and that’s where you’ll go to see details about the quality of the air. air in the room.

The Coway Airmega 250 is an air purifier, on the other hand, designed to stand on the ground, like the Coway Airmega 150. It is more rectangular and also has a power cord. But unlike the Aura Air, it’s not a smart device, and all of the controls – or features – are handled directly from the purifier itself.

Coway Airmega 250 also includes pre-filter, carbon filter and HEPA filter



The Aura Air has two filters, one is a pre-filter, which most purifiers use, which is designed to capture things like hair and larger objects. Then there is something that Aura Air calls a spoke filter, which is the main one for this device. This includes a HEPA filter, carbon layer, and antibacterial layer, and is intended to remove VOCs, odors, bacteria, tiny tiny particles and more down to 0.3 microns.

The Coway Airmega 250 also has a pre-filter. Then there is an activated carbon filter, this will help remove odors, and finally what the company calls a Green True HEPA filter which is designed to capture VOCs, as well as very fine particles, allergens and contaminants. down to 0.3 microns.

Monitoring functions

Aura Air is designed to function as a monitor and delivers an AQI score (also known as an air quality score) by capturing seven different parameters in the air: carbon monoxide, carbon dioxide, VOCs or products chemicals, PM10 or standard particles, PM 2.5 or very small fine particles, humidity and temperature. You can also see it on the front of the device through a small light indicating the air condition, as well as in the app – and the app is extremely well designed.

The Airmega 250 also monitors the air in a space – this is how it determines when to start cleaning or not. These details are not as detailed as with the Aura Air, but are also presented to you with information about the cleanliness of your space via a large color indicator on the front of the purifier. These range from red, meaning bad, to green, yellow, and blue, meaning the air is good.

There is also a unique security lock on the front of the Airmega 250 which, when pushed in, prevents settings from being changed by little fingers or anyone else.

The Aura Air? Honestly, it’s a bit louder when it’s up and running. Although the sound was not constant, when the device certainly felt that the air needed a heavy cleaning, I could hear it and it was enough that you might not want to install this purifier in a bedroom or even a home office. When not in this intensive cleaning mode, the Aura Air was quite quiet.

At higher levels the Coway Airmega 250 was also very loud. This purifier ranges from level 1 to level 3, the latter being the loudest of all. On the lowest setting we found the device to be very quiet, almost silent. But when it comes into play, if the auto setting is eg, then it was a fan level that would make it difficult to hear a video conference call.

Smart controls

As the Coway Airmega 250 is not a smart device, you cannot connect to voice assistants or an app. For some, this can be positive. It has some automation, in that it can operate and go through various settings, including eco mode for sleeping, on its own by monitoring air quality and making choices as to when. where it should go into high cleaning mode or not.

Aura Air, as a smart device, uses an app to provide air quality details and also claims to work with two voice assistants, Alexa and Google Assistant. We were able to connect to Amazon’s voice assistant in our testing, but not to Google Assistant.


Aura Air sells for $ 499 on the company’s website. Its Ray filter, which you’ll need to replace at some point, is also $ 79.

The Coway Airmega 250 is available on the company’s website for $ 399.

Aura Air

What is right for you?

For starters, anyone looking for a smart device that can work with voice assistants and has an app, the Aura Air will probably be a better choice. The device can be operated via Amazon Alexa (we had issues with Google Assistant) and can be controlled via a smartphone, where you can also get details about your air quality.

The Coway Airmega 250 will probably appeal to someone who wants some automation, but doesn’t want to have to connect the device to Wi-Fi. It can still handle large spaces, over 900 square feet, and that’s even a little cheaper than the Aura Air. You can also just plug it into an outlet and let it run.

The Aura Air is intended to be mounted on the wall, which does add a bit of extra work to its setup, but from there you won’t need to touch the device much unless you change the filter or reset the Wi-Fi. (Something we had to do during our testing.)

We like the look of the Aura Air better, which sports a clean almost architectural design compared to the square look of the Coway 250, and it can also clean a fairly large space, up to 600 square feet. But at the end of the day, the decision of what someone needs in their space is yours.

For those who prefer a hands-on approach, the Aura Air may be more to their liking, while someone who needs to clean a larger area and wants more visible clues to the air quality on the device. , may want to consider slightly cheaper Airmega 250.
