Frequently Asked Questions

Common questions about this comparison

Which is better for large spaces?

Coway Airmega 400 is ideal for large spaces, covering 1,560 sq. ft. compared to Dyson's 400 sq. ft. Its higher smoke CADR of 328 ensures faster purification in bigger rooms.

What's the main difference in purification power?

The Coway Airmega 400 has a much higher smoke CADR of 328, covering 1,560 sq. ft. The Dyson Purifier Cool PC1 has a lower smoke CADR of 76 and covers 400 sq. ft., but also functions as a fan.

Is the Dyson's combined fan feature worth the trade-off?

If you need both air purification and a cooling fan for a smaller room (up to 400 sq. ft.), the Dyson is a good choice. However, for dedicated, large-area air purification, the Coway offers superior performance.

Which offers quieter operation?

The Coway Airmega 400 can operate as quietly as 22 dB at its lowest setting. While Dyson's minimum noise isn't specified, its primary function as a fan suggests it may have higher noise output during cooling.
