nataku411This air purifier does not use a consumable filter. As long as the dust from the inlet and outlet are occasionally cleaned it will continue to function properly.
AnzialHi,
The fan, like most other fans, does not require any maintenance.
The length of life for this and all electronics cannot be guaranteed because there are lots of factors that come into play. The better the device is handled, the longer it will last.

papagoLength of life cannot be guaranteed. What does "better device handling mean"? What's the failure rate? What's the longest a device has lasted?
Your answer is a non-answer.
paulrulesIf they give a definitive answer then they will be held to that legally. I sharpen knives and people always ask me "how long will these stay sharp?" the answer is the same, depends on the steel, how you use them, how much you use them, how/if they're abused, etc etc... If I say "6 months" then they go home and saw on chicken bones with them, they get upset that they're dull again before 6 months. In other words, treat it properly, don't abuse it, and it should last a lifetime. Anything beside that and your mileage may vary.
