Three Ways to Improve Indoor Ventilation to Combat COVID-19
Data compiled by the world health organization (WHO) shows that poor ventilation can lead to an increase in virus transmission. As such, improving ventilation indoors should be considered an important step in reducing the spread of viruses such as COVID-19. This article covers three simple steps to improve indoor ventilation and lower the risk of […]
How Long can the Coronavirus Survive on HEPA Filters?
Air purifiers with HEPA filters are highly effective at filtering out viruses such as the COVID-19 coronavirus. But viruses can remain on surfaces for scarily long periods of time. When thinking about viruses stuck in an air purifier’s HEPA filters, that sounds scary. It’s also led to incredible-sounding headlines about how long viruses last. But […]
Can Opening Windows & Doors Reduce COVID-19 Transmission?
Data shows that having good indoor ventilation can reduce the chance of virus transmission. Armed with that knowledge, can something as simple as opening a window be effective solution to fighting COVID-19 and reducing virus transmission indoors? Recommended Air Changes Per Hour Before we can say how effective opening windows really is, we […]
Can HEPA Filters Release Dirty Particles Back Into the Air?
HEPA filters are great at filtering particles such as dust, PM2.5 and PM10. They also do an incredible job of capturing nanoparticles including viruses and bacteria. What HEPA filters don’t do though, is destroy the particles. This has lead to a lot of marketing hype and confused air breathers. Some companies claim they have superior […]
