The nasal pillows cushion for the AirFit X30i is designed to create a seal with minimal facial contact and deliver airflow directly at the nostrils while reducing bulk on your face. This dual-wall silicone cushion adapts to movement during sleep, helping you stay sealed even if you turn or shift positions. Its under-the-nose design leaves the bridge of your nose untouched, avoiding pressure and keeping your field of vision clear. Note: This is only the nasal pillows replacement cushion for the AirFit X30i mask. It works with all X30i frames and the standard oral cushion. Be sure to select the correct size that works for you: Small, Medium, or Large.
