Frequently asked questions

Is the Coway Airmega 450 quiet?

On its lowest speeds, yes - I forget it is running. The top speed is loud, but auto mode rarely calls for it.

Are the replacement filters expensive?

No, and that is one of its strengths. Prices move, so check the current cost before you buy.

Is it worth buying at full price?

I would wait for a sale. It is a strong purifier, but at list it is a lot to pay.
