The Sqair E12 filter protects you from China’s air pollution<\/strong><\/h2>\n

China’s air pollution has been a recurring environmental and health problem. Despite small improvements during the COVID-19 lockdown, air quality in all of China\u2019s major cities were still <\/span>over the WHO limit<\/a> in 2020.<\/span><\/p>\n

The Sqair’s E12 filter effectively traps particles like PM2.5, dust, pet fur, viruses and mold, giving you cleaner air in your bedroom. Sleep more easily without worrying about allergies or asthma.<\/p>\n<\/div>\n<\/colgroup>\n\n\n\n

Can HEPA\/EPA filters capture the coronavirus?<\/strong><\/h2>\n

A common concern is whether HEPA\/EPA filters can filter viruses like the COVID-19 coronavirus. HEPA\/EPA 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\/EPA filters actually work great <\/b><\/span>at capturing viruses. This is because a HEPA\/EPA 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\n

How long can I use the Sqair E12 filter?<\/strong><\/h2>\n

Filter lifespans are tricky. Purifier companies like to give lifespan numbers without proper reasoning. Clearly, the HEPA\/EPA filter will not last as long in Beijing air as compared to Swiss air.<\/p>\n

We estimated the lifespan of the Sqair\u2019s E12 filter using two methods<\/a>. From the data, we recommend up to 1400<\/strong> hours of use. This is roughly equal to 6 months if you use the purifier 8 hours a day.<\/p>\n

On high mode, this is equivalent to:<\/p>\n<\/div>\n

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

Unfortunately not.<\/b> We ran experiments to test this and found that washing HEPA\/EPA filters does not prolong their lifespan<\/a>. In fact, washing HEPA\/EPA filters with water actually decreases<\/b> performance. That\u2019s why we recommend you replace your Sqair E12 filter after the maximum hours of use.<\/p>\n
