Blast HEPA’s massive area captures 99.95% of pollutants
The Blast HEPA filter is huge — 20 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!

Can HEPA filters capture the coronavirus?
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 actually 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 the HEPA?
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 5280 hours for the Blast. This is roughly equal to 22 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 HEPA filter after the maximum hours of use.
At only $150 for two years of clean air, the Blast HEPA offers you the best prices for clean air.
Time to change the HEPA?
You’ll only need to change it every 22 months, but we still try to keep things simple.
