ResMed SpringFit Frame for AirFit N30i / AirFit P30i

The SpringFit Frame for the AirFit N30i and AirFit P30i is a replacement flexible silicone chassis designed for active side sleepers who use a tube-up-the-head mask configuration. Over weeks of daily air pressure, facial contact, and cleaning, the internal silicone pathways can soften, stretch, or discolor, affecting the mask’s alignment and cutting off air pathways when compressed. This replacement chassis restores the mask's original structural geometry, ensuring that air flows smoothly and evenly through the side channels down to your nose.This frame incorporates an innovative self-adjusting accordion structure between the cheek and the top swivel connection, allowing it to stretch or compress automatically to match your specific facial height. The ultra-smooth silicone rests gently against your cheekbones, eliminating the need for hard plastic support pieces or a heavy forehead brace. Swapping out a worn chassis preserves clear airway delivery and prevents localized pressure marks, letting you move naturally and sleep in your preferred position.
