About Coway Airmega 400 Smart Air Purifier with 1,560 sq. ft. Coverage, White
Overall Feedback:
71% positive
85% were satisfied with the size and portability
The filter provides phenomenal filtration for a space of approximately 600 sq ft.
I bought a Coway Airmega 400 for my living area and it was a huge improvement. I keep the 250 permanently in my bedroom, so not having to drag a purifier around is a nice cherry on top.
The air purifier is compact yet powerful and suitable for rooms of various sizes, including larger areas up to 1,560 square feet.
95% appreciated the quiet operation
I like the noise level of the air purifier. There is hardly any noise unless I cook something that produces smoke or run my essential oil diffuser nearby.
When smart mode detects pollutants in the air, the sound adjusts up to the highest level which can be somewhat loud. However, I can manually adjust it to stay at the lowest level if I dont want any background noise.
On the lowest level, the sound is soft and has not been distracting during my daily routines.
Even at higher fan speeds, I can enjoy my surround sound without any disturbance as the noise level remains minimal.
