Comfort

• Thermal comfort
  A ventilation system with heat recovery keeps the temperature of the room air at a comfortable level, as it is preheated before entering the room. In this way, the existing energy is further utilised and the occupants benefit from savings in their heating costs.
• CO2 – Fresh air 
  The level of CO2 (carbon dioxide) in the room air indicates how “stale” this air is. Carbon dioxide causes headaches, fatigue and exhaustion. Therefore, this factor is significant with regard to comfort.
• Risk of draughts
  Everyone is familiar with draughts. They are not only unpleasant but can also increase the risk of catching a cold. So comfort is also an issue when it comes to draughts.
• Pollutants from outside
  The concentration of allergy-causing substances such as dust, pollen, insects, spores, etc. in the indoor air represents a restriction of the quality of life, especially for allergy sufferers. While window ventilation opens the door to these factors, ventilation systems use filters that offer effective protection.
