Benefits: The use of the Propolair L2 propolis diffuser with ionizer is effective: in cases of asthma chronic bronchitis nervous tension and stress respiratory tract infections How does it work: Kontak PropolAir propolis diffusers use heat to extract and diffuse the volatile fraction of propolis into the environment. When switched on, the appliance heats the propolis contained in a capsule to pre-established temperatures. Once the optimal temperature has been reached, the volatile fraction is released and can thus be ingested both via respiratory and percutaneous routes. All Propolair propolis diffusers use standard Kontak capsules produced with pure Italian and certified organic propolis. The propolis diffuser with ionizer is an easy and safe tool to use and can also be kept on during the night.
