For example air purifiers with HEPA (with High Efficiency Particulate Air) filters – they are the perfect innovative solution. Especially during the cold months when we spend most of our time behind closed doors. As we all know people can infect with Covid-19 by inhaling it from air that we share. The virus particles are tiny and often linger in the air in closed spaces.
Experts are saying that air purifiers with HEPA and HyperHEPA filters can remove 99% of small particles. Those devices are also relatively cheap; simple; quick and effective ways to clear potentially infectious aerosols.
Therefore, they are a helpful way to filter bacteria, airborne viruses, and small particles. They can’t entirely eliminate Corona transmission, but still can help to reduce the risk. Especially when they are in use with all the known protection methods as wearing masks.
This approach is thoroughgoing and some schools over the world started programs for installations of air purifiers in glass rooms and teacher’s offices.
Their units are already available for online purchasing and the shipping is very easy via all the existing delivery services. The logistics are not so expensive, neither complicated.
Also the installation – it takes minutes. The one and only thing to think about is the need of ensuring proper PPE when the filter needs changing.
Combining air cleaning devices with other risk-reduction ways, we can achieve an affordable way to reduce the risk of viruses spread between unvaccinated people and households.
Their technologies can be separated into four categories: catalytic oxidation; ultraviolet disinfection, electrical ionization and filtration. Some of those technologies have been famous for decades. Still the biggest question is – are they effective against coronavirus?
So far, some of them have solid data, but others still need more studies. An air purifier can be a solution in cleaning the air from pollutants and viruses, but can’t stop all variants of transmission. We have to work everyday to find more innovative wa
