HEPA filters capture particulate pollution like PM2.5 and pollen, and are the key to clean air. This is the replacement HEPA filter for the Blast Mini air purifier.

 

Blast Mini HEPA filters give you clean air in your home/office

Purifier companies can make obscene profits when most people don’t understand how purifiers work. Here’s the honest truth: a purifier is fan + a filter. In this case, the Blast Mini HEPA filter is just 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!

 

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 3120 hours for the Blast Mini. This is roughly equal to 13 months at 8 hours of use every day. With Bangladesh’s air quality roughly comparable to Beijing, you can rest assured that these numbers will not vary much in Bangladesh.

Time to change the HEPA?

You’ll only need to change it every 12-13 months, but we still tried to keep things simple.

 

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.

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.
