Frequently Asked Questions
Which is quieter?
The Coway Airmega is slightly quieter across all speeds, with a lowest rating of 24.4 dB vs the Winix at 27.5 dB. Both are bedroom-friendly on low.
Which has lower total cost of ownership?
Over 3 years, the Winix 5500-2 has lower total cost due to its washable carbon filter. Coway's disposable carbon filters add about $30-40/year in extra costs.
