profi-air®: heat recovery ventilation healthy & efficient
Heat recovery ventilation is far more than just creating a sound room climate. Since healthy ventilation of a building ensures stable value of the entire property: heat recovery ventilation maintains the structural fabric and therefore the resale value of the building by preventing humidity-related
damage and mould growth. At the same time, heat recovery ventilation reduces heating requirements since less energy escapes through manual airing. Filtered air adjusted to a pleasant temperature ensures a healthy and comfortable climate in all rooms.

In addition, antistatic and antibacterial agents make the products absolutely sterile.

Good air with heat recovery ventilation

We spend about half of the day in our own home. The room climate is an important factor for us to feel truly comfortable at home: Firstly, fresh air rich in oxygen positively affects our health; and secondly, regular air exchange prevents the spread of pathogens. And that because ventilation helps to keep the concentration of viruses and bacteria in the ambient air at a low level.
Yet, manual airing requires action of the residents – not everyone though has enough time or remembers to regularly air all rooms in a sufficient manner.
Heat recovery ventilation combines a number of advantages: It performs constant air exchange in the entire house or apartment autonomously. Used room air is automatically replaced with fresh outside air. During this process, the outside air is filtered to make sure that no pollutants, pollen or viruses enter the living quarters.
