The lifespan of an air purifier is not to be confused with the lifespan of the HEPA and carbon filters. More information on HEPA and carbon filter lifespan, see the separate answers for Sqair HEPA filter lifespan and Blast & Blast Mini filter lifespan.
Now, how long do Smart Air purifiers last? We work hard to keep our Smart Air purifiers as simple as possible. In essence, they’re just a fan and a filter. This simplicity not only makes Smart Air’s purifiers more efficient and cheaper, it also means they last a long time. The only mechanical item in the purifiers is the motor. We run tests on all our purifier motors, and they’re proven to run for at least 10,000 hours.
That’s a minimum number, and means the purifiers would run a minimum of 4-5 years if running them for 6 hours per day. Typically, the motors last much longer. We’ve seen Smart Air purifiers in use 7 years after they were purchased, still working without issue.
