A biow ionizer is an electrical, fully automated device that produces negatively charged electrons. These electrons are also called ions. Biow's high-tech device can easily run 24 hours a day. It uses very little electricity (< CHF 3 per month). The ions serve to reduce certain particles in the air, such as dust and pollen, and to improve the air in the long term. The room air is refined in this way with the help of the ions. This ensures better air quality and a noticeably greater sense of well-being.
