Blast H13 HEPA Filter<\/strong><\/h1>\n

Clean air in your office and hospitals<\/h4>\n<\/div>\n<\/div>\n

The Blast HEPA protects you from pollutants and COVID-19<\/strong><\/h2>\n

Air pollution is a serious environmental and health issue. Tiny microscopic particles can slip past our body’s defences and penetrate deep within our lungs and heart. Clean air in our homes is all the more important during the COVID pandemic.<\/p>\n

The Blast’s HEPA filter effectively traps particles like PM2.5, dust, allergens, bacteria, and viruses. Enjoy worry-free clean air in your hospitals and offices!<\/p>\n<\/div>\n\n\n\n\n<\/colgroup>\n\n\n\n

Blast HEPA’s massive area captures 99.95% of pollutants<\/strong><\/h2>\n

The Blast HEPA filter is huge \u2014 20 times the size of our Original DIY HEPAs.<\/p>\n

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! The Blast HEPA’s efficiency means it’s suitable for health facilities like hospitals.<\/p>\n

Are HEPA filters effective against COVID?<\/strong><\/h2>\n

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<\/span>, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns <\/span>in diameter. Are air purifiers then powerless against viruses?<\/p>\n

Actually, HEPA filters actually work great <\/b><\/span>at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion<\/b><\/span>. Learn more about how this works here<\/a>.<\/p>\n<\/div>\n<\/div>\n

\n
\n

How often should I change the HEPA?<\/strong><\/h2>\n

We tested a HEPA in real Beijing air for 200 days to get a sense of how long HEPAs last in real Beijing air.<\/a><\/p>\n

Based on that data, Paddy estimated a HEPA lifespan of 5280 hours<\/strong> for the Blast. This is roughly equal to 22 months<\/strong> at 8 hours of use every day.<\/p>\n<\/div>\n\n\n\n\n<\/colgroup>\n\n\n\n\n

Can I wash a dirty HEPA filter?<\/strong><\/h2>\n

Unfortunately not.<\/b> We ran experiments to test this and found that washing HEPA filters does not prolong their lifespan<\/a>. In fact, washing HEPA filters with water actually decreases<\/b> performance. That\u2019s why we recommend you replace your Blast HEPA filter after the maximum hours of use.<\/p>\n

At \u20b1<\/span>6150 for two years of clean air, the Blast HEPA offers you the best prices for clean air.<\/p>\n<\/div>\n<\/div>\n

\n

Time to change the HEPA?<\/h2>\n

The Blast is easy to use. You\u2019ll only need to change it every 22 months, but we still tried to keep things simple.<\/p>\n
