Waves improves the indoor air quality by freeing bathrooms and kitchens from unpleasant odours and moisture. Thanks to its integrated sensors, the decentralised mechanical ventilation automatically adjusts its operation and ventilation level to the current humidity level in the air and to any prevailing odours. Waves is also available in a version with an addi­tional CO₂ sensor. If the CO₂ level indoors gets too high, Waves increases the ventilation level in the bathroom, toilet or kitchen to bring the indoor air quality back to a safe level.
