Ventilation without humidity recovery is only a halfway solution. Using it will reduce the relative humidity in your home to 10-20% during the heating season.

Big Magic has a unique heat exchanger with humidity recovery as standard. Thanks to the enthalpy exchanger, you will not only have the ideal temperature but also the ideal humidity in your home.

In addition to energy savings, filtration is the main added value of controlled ventilation with heat recovery. Unlike window ventilation, the fresh air is free of most pollutants.

Big Magic filters provide effective protection against pollen and are therefore suitable for people with allergies. They have a large filtration surface of over one square metre. We guarantee the best price/performance ratio on the market so that you do not have to skimp on filter replacement.

Thanks to its unique design, Big Magic works without preheating even at –20 °C, with an average power consumption of 40 watts!

It is not hard to calculate the difference: The amount of energy used by a standard ventilation unit
with preheating in a single day of operation is enough to power a Big Magic unit for a month.

Big Magic adjusts the ventilation intensity based on air quality inside the house, which is detected by CO2 sensors. Big Magic ventilation always comes with
at least one controller with integrated CO2, temperature and humidity sensor
ncluded in the price of the unit.
