How Long Does the Sqair’s HEPA Filter Last?
After launching the world’s most cost-effective purifier (the Sqair), we started testing the HEPA lifespan.

What’s the HEPA Lifespan of the Blast and Blast Mini?
Ever since we launched the Blast and Blast Mini in 2017, we’ve wanted to get good data on how long hepa filters last. These filters are huge, 10-20 times the size of our DIY purifier filters in fact.
