The Blast HEPA protects you from Bangladesh’s pollution<\/strong><\/h2>\n

Bangladesh air is filled with pollutants that are harmful to our health. Air pollution is hard to escape \u2013 even our homes are filled with these dangerous microscopic particles.<\/p>\n

The Blast’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!<\/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!<\/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

How often should I change my Blast HEPA filter?<\/strong><\/h2>\n

Bangladesh, and especially Dhaka, has one of the highest air pollution levels in the world<\/a>.<\/span><\/p>\n

Because of severe air pollution levels in Bangladesh the Blast HEPA filter lifetime is less than in other countries. We recommend replacing your filter after 15 months of use (at 8 hours a day) at the latest. That\u2019s maximum 3800 hours in total; this is the amount of time you can run your Blast air purifier before needing to change your filters. <\/span><\/p>\n

However, you should still check your HEPA filter at regular intervals. Use our filter lifetime calculator<\/a> to determine when to change your HEPA filter.<\/span><\/p>\n

We know that buying new HEPA filters is a significant recurring cost, so we do our best to keep prices low.<\/span><\/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 BDT 25,000 for 12 months of clean air, the Blast HEPA offers you the best prices for clean air.<\/p>\n<\/div>\n<\/div>\n

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

You\u2019ll only need to change it every 15 months, but we still tried to keep things simple.<\/p>\n
