GGM, a Taiwan BiPAP mask manufacturer, designed the MDA nasal mask to fit snugly over the nose. Compared to full-face masks, it makes less contact with the face, offering greater comfort for some users. The mask also minimizes air leakage, enhancing the effectiveness of the therapy. Moreover, we supply a diverse selection of respiratory care products, including Siemens filter for bacterial filters, HEPA bacteria filters, and oronasal masks.
