Smart Air purifiers can contain both HEPA and carbon filters. The lifespan of each varies with usage and the purifier.
When Should I Replace the HEPA filters in my Smart Air Purifier?
The HEPA filter lifespan varies for each purifier. For an up-to-date list of each of our air purifier’s HEPA filter lifespans, check out our air purifier overview and manuals page.
How long do the carbon filters last in my Smart Air purifier?
What Else Should I Know Before Replacing My HEPA Filter?
Many purifier companies give just a single number for the lifespan of HEPA and carbon filters. However, in reality, the true lifespan of each filter will depend on where the purifier it used, how long it is run for, and how dirty the air is where the purifier is running.
We don’t like these standard numbers most companies give. That’s why we make sure to run real-world tests on all our purifiers, and provide explanations on how to adjust the numbers for where you live.
For example, if the Blast Mini is used for 8 hours everyday in an 80m² room on the lowest level, the filter can be used for 13 months (or 3,120 hours). If it is used on the highest level, it can last for 12 months (or 2,880 hours).
If the Blast is used for 8 hours everyday in a 130m² room on the lowest level, the filter can be used for 22 months (or 5,280 hours). If it is used on the highest level, it can last for 19 months (or 4,560 hours). Do determine its lifespan based on usage.
