Optimization of the Internal Climate in the Hospital

Did you know that dry air in buildings can cause more problems than humidity? Too high humidity is obvious and is usually dealt with immediately. We are rarely aware of dry air yet it is very harmful to our health.

Ideal Relative Humidity

Relative humidity measures the amount of water vapor in the air. The optimal value is considered to be between 40-60% relative humidity. The problem often arises in winter, during the heating season, when the interior air humidity can decrease to 20%. The air inside the buildings is dried because of heating and the outside air is very cold and also very dry. Therefore, even ventilation can’t effectively increase the air humidity in the room.

The problem with dry air can arise also in the summer. Poorly constructed buildings often overheat during the summer heat and all the moisture evaporates in the interior.  

Dry air is unpleasant to breathe and a long stay in a room with dry air is harmful to health. Dry air takes a large amount of water from our body; this leads to drying out the nasal mucous membranes, eyes, and face, they become irritated and swollen. The result is a stuffy nose, cough, sore throat, inflamed conjunctiva and cornea, and headache.

Optimal relative humidity contributes to a lower rate of airborne transmission of viruses. The viability of enveloped viruses (influenza, herpes, coronavirus) is highest at 20% relative humidity and decreases at 60% relative humidity.

People come to hospitals to recover. It is therefore extremely important to create there an environment where they can heal better – optimally humidified air significantly contributes to this goal.


Dry fog humidification can increase the relative humidity in a short time. Miniature drops of water in the form of dry fog are dispersed into the space and evaporate while still in the air. Due to their micro size, they never fall on the surface and leave no trace of water.  

AKIMIST® Mobile Unit

AKIMist® Mobile Unit sprays dry fog that reliably humidifies the air but doesn’t condensate on the walls and floor. It can maintain a stable humidity level between 60 – 65% RH. It is an easy-to-use device with a pressurized water tank ready for immediate use. You can choose between one or two adjustable nozzles. One nozzle can humidify 100m3.

Smart dry fog controller

If you are looking for a more complex solution, we have a Smart Dry Fog Controller. The system consists of AKIMist® nozzles, a reverse osmosis device, a timer, and an air humidity sensor. The system automatically manages optimal air humidity in the space. The system is almost maintenance-free when you are using demineralized water. It can be used in both large and small spaces.


  • Stable optimal relative humidity
  • High performance
  • Low maintenance costs and requirements
