Sometimes bigger is better, especially when it comes to air filters and air purifiers, where a larger inlet, fan, and filter surface area can make a significant difference in removing unwanted contaminants quickly. The previous work of the Korean device brand Coway, the Airmega 150, convinced us with its combination of minimalist, decor-friendly design and quiet efficiency (the compact design has also been awarded numerous industrial design prizes, including a 2020 Good Design Award and iF Design Award, that never hurts). Your continuation Airmega 250 is similarly designed to fit into a room, with some upgrades and a larger size.
The new Airmega 250 is not only significantly larger than the Airmega 150, it also contains a newly developed washable “EZ Release” prefilter as part of the 3-stage filter system of the air purifier, an activated carbon filter and a Green True HEPA filter that is being developed has been designed to capture and inactivate 99.999% particulate matter such as viruses, bacteria, fungi and pollen down to 0.011 micrometers. Coway also claims that its filtration system inactivates and kills up to 99.99% of the viral, bacterial, and fungal contaminants that are all trapped by the filter.
The design itself remains noticeably similar in shape, with dimensions stretched to a wider shape (18.5 x 19.7 x 8.3 inches), allowing for a larger inlet and filter area inside, and more like a Furniture is designed as a home appliance (markets outside of the US offer two colors and two design options, compared to the single champagne beige finish sold here). Unsurprisingly, this sequel design has also been nominated for a 2021 design award for its sleek and harmless home appliance shape.
Coway also added a larger real-time air quality monitor display on top of the Airmega 250, which uses a four-color system to communicate good (blue), moderate (green), unhealthy (yellow), or very unhealthy (red) air quality at a glance; a smaller indicator lights up when either the Pre or Max2 filter needs to be replaced.
The only thing missing from our book is WiFi network compatibility and app integration (both for planning and monitoring air quality). Compatibility with Coway’s Mobile IoCare app and voice control via Amazon Alexa and Google Home, with the possibility of app-integrated air quality monitoring and reports providing additional benefits.
