Virus protection

Do I still have to wear a face mask?

The coronavirus and the related COVID-19 disease are unfortunately still spreading all around the world. For more than 20 years, we at Stadler Form have been improving the indoor air of our customers with our innovative appliances. Your health is our most important asset. This is why we check the latest research and scientific reports about the coronavirus regularly and publish what we find important on this blog.


Are you tired of wearing a mask that covers your face? Then watch this video or read on.

Unfortunately, we have to disappoint you if you thought you could get rid of the face mask. We’ll explain to you, why it is still very important to wear one. Therefore, we present you some new evidence of the spread of the new coronavirus (SARS-CoV-2).


Japanese researchers used a supercomputer called Fugaku, to better understand the spread of the coronavirus in different conditions. What they discovered is definitely interesting and worth mentioning. They found out, that in a dry room with a humidity level of 30% or lower the number of aerosols* is more than double than the number of aerosols in a humid room with a 60% humidity level or higher. The bottom line is, that those Japanese researchers recommend using a humidifier in order to reduce the exposure to the virus. Especially during the time of autumn and winter, when it’s cold outside and you cannot ventilate as often as you would need to. Therefore, switch on your humidifier and stay healthy during this time.


So, the conclusion of these findings is the following: When you go outside, use your face mask to protect yourself but also the other people around you, socially distance you and wash your hands as often as possible. For indoors: monitor the air humidity to ensure it is within the recommended range of 40–60%. Use a hygrometer such as our Selina little for monitoring the indoor climate. Use a humidifier when your indoor humidity is below 40% to bring it back to a healthy level.


Stay healthy and stay safe!


*Definition of aerosols according to Wikipedia: An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas.
