The Blast Mini HEPA filter protects from China’s air pollution
Air pollution in China has been a serious environmental and health problem for decades. Despite small improvements during the COVID-19 lockdown, air quality in all of China’s major cities were still over the WHO limit in 2020.
The Blast Mini’s HEPA filter effectively traps particles like PM2.5, dust, pet fur, viruses and mold. You won’t have to worry about your allergies or asthma any longer!

Blast Mini HEPA’s massive area captures 99.95% of pollutants
The Blast Mini HEPA filter is huge — 10 times the size of our Original DIY HEPAs.
We tested over 10 different HEPA materials before deciding on using an H13, 99.95% grade HEPA filter. That means it can capture 99.95% of those particles above (and below) 0.3 microns!

Are HEPA filters effective against COVID?
A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA filters removes particles greater than or equal to 0.3 microns, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns in diameter. Are air purifiers then powerless against viruses?
Actually, HEPA filters work great at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion. Learn more about how this works here.
How often should I change my Blast Mini HEPA filter?
We tested a HEPA in real Beijing air for 200 days to get a sense of how long HEPAs last in real Beijing air.
Based on that data, Paddy estimated a HEPA lifespan of 3120 hours for the Blast Mini. This is roughly equal to 13 months at 8 hours of use every day.

Can I wash a dirty HEPA filter?
Unfortunately not. We ran experiments to test this and found that washing HEPA filters does not prolong their lifespan. In fact, washing HEPA filters with water actually decreases performance. That’s why we recommend you replace your Blast Mini HEPA filter after the maximum hours of use.
At ￥450 for a year of clean air, the Blast Mini HEPA offers you the best prices for clean air.
Time to change the HEPA?
You’ll only need to change it every year or so, but we still tried to keep things simple.
