Coway warranty for air quality
The short version
Coway covers air quality in full for 1 year, with no partial coverage after that. That full coverage is the same as most of the 30 brands we compared, which typically cover 1 year in full. You don't need to register to get this coverage.
From Coway's published warranty, checked October 2026.
