ResMed AirFit N30i Nasal Replacement Cushion - Small

In this review the ResMed AirFit N30i Nasal Replacement Cushion (Small) is assessed for CPAP users who need a reliable nasal cradle cushion that prioritizes quiet therapy and a secure seal. The bottom line: this replacement cushion is best for users who value the top-of-head tube routing and QuietAir diffusion for reduced noise, and who want a heavy-duty silicone option that lasts with monthly replacement. It is reviewed here as a practical, comfort-focused part rather than a mask, and performs well on fit and airflow while showing mixed feedback on softness and long-term comfort.

Key Features

• Designed for the AirFit N30i: Replaces the original nasal cradle cushion to maintain a secure seal with the AirFit N30i mask and preserve intended mask performance.
• QuietAir Technology: Diffuses exhaled air to reduce sleep therapy noise for the user and partner, helping sustain a calmer bedroom environment.
• Heavy-duty silicone construction: Made from durable silicone for extended daily use while still recommended to be replaced monthly to ensure hygiene and seal quality.
• Nasal cradle design: Rests under the nose to direct airflow into the nostrils and minimize leaks without covering the bridge of the nose.
• Top-of-head hose compatibility: Works with the AirFit N30i top-of-head tube routing to allow greater freedom of movement during sleep.

Who It's For

This cushion suits CPAP users who already own the AirFit N30i mask and want an authentic replacement piece that preserves the mask's original fit and QuietAir comfort features. It is particularly well suited for light to moderate sleepers who appreciate top-of-head tubing and want minimal mask contact around the face.

Those who prefer very soft, pillow-like silicone or who consistently report discomfort with nasal cradle styles may want to try a different cushion shape or size; customers have mixed views on cushion softness, so anyone sensitive to firmness should consider trying a single replacement before committing to a long-term supply.
