The straight-type heat and moisture exchange bacterial filter (HME) not only provides warmth and humidity but also filters out microorganisms and suspended particles from the patient's exhaled air, reducing the particles and bacteria in the patient's exhalation. GGM's new hygroscopic Microwell paper media offers optimal moisture output with low resistance to airflow. Moreover, we supply a diverse selection of respiratory care products, including medical headgears, spirometry filters, and breathing bags.
