The effects of temperature and humidity on COVID-19 Corona virus

We are confronted with it several times a day by different media. COVID-19, better known as the Corona virus, is spreading rapidly around the world and is having an increasing impact on our daily lives. Although this is not s direct cause for concern, it is good to take certain things into account in order to minimize the risk of infection..

In addition to considering our personal hygiene and keeping utensils clean, good air humidity can help reduce further spread. “The COVID-19 virus can only withstand heat and humidity”, according to an infection expert from the RIVM¹.  

Temperature and humidity

Previous research² has also shown that above a relative humity of 80% or lower than 20%, most corona viruses are still active after two days at a constant temperature of 20 degrees Celsius. At a constant temperature and relative humidity of 50%, less than 1% of the viruses survived after 2 days.












The ambient temperature can also have a strong influence on the activity and spread of viruses. For example, other viruses that cause respiratory infections often occur in the winter months. There are indications that this is due to a reduced resistance of the mucous membranes in the nose when cold air is inhaled³

Measure to know

So how do you quickly find out the air quality in your area? A healthy (relative) humidity is on average between 40% and 60%. Besides the fact that (too) dry air can lead to complaints such as headaches, dizziness and irritated skin, it can also increase the survival time of viruses and bacteria. A portable hygrometer such as the Duux Sense can help you quickly gain insight into the relative humidity of any room.

If you notice that the air in your environment is too dry and you want to quickly increase this, you can opt for an ultrasonic humidifiers. For example, Tag is suitable for spaces up to 30m² while Beam can manage to cover spaces up to 40m². Beam is also equipped with a built-in hygrometer and can be controlled remotely with our new Smart App. A combination of humidifiers is also always possible to cover larger areas.


If you prefer a natural way of humidification, then Ovi and Motion could offer a solution. Both devices only humidify when necessary. This eliminates the risk of over-wetting. Another advantage is that these types of humidifiers also have an air cleaning function. Airborne particles are captured in Ovi’s PET+Nylon water filter while Motion is equipped with a carbon filter to remove harmful substances and gases from the air.

Disclaimer: Unfortunately our products cannot protect you against the COVID-19 virus. However, we can contribute to improving the air quality in your environment so that bacteria and viruses spread less quickly and remain active for a shorter period of time.
