Purifoam uses a high quality medical grade foam that protects the stoma from dirt and dust entering the airway, while warming and humidifying, the incoming air. The filter is adhered to the skin using a skin friendly hypoallergenic pressure sensitive adhesive strip that has rounded edges for additional comfort.

Manufactured from beige coloured foam to give a natural aesthetic look. Purifoam is developed to have moisture retaining qualities, therefore ensuring good levels of absorbency and humidification to incoming air.
