Molekule warranty for air quality
The short version
Molekule doesn't cover everything, but keeps whole product (certified refurbished units) covered to 1 year. That full coverage is shorter than 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 Molekule's published warranty, checked October 2026.
