Fisher & Paykel 400BRE113 Brevida Nasal Pillow Mask AirPillow Seal XS-S

• Model: 400BRE113
• Size: X-Small / Small

The Fisher & Paykel Brevida with the 400BRE113 Extra‑Small / Small (XS‑S) AirPillow seal is designed for users with smaller nostril or nose dimensions who need a gentle yet reliable seal for CPAP or BiPAP therapy. The AirPillow cushion is very thin and soft silicone, which inflates when pressure is applied, forming both an internal seal inside the nostrils (lightly) and around the base of the nose. Because the walls of the cushion are thin, the contact with the face is minimized, helping avoid soreness or pressure marks, especially for those sensitive around the nose. The XS‑S size reduces bulk and potential leaks for smaller nose shapes, without forcing over‑fitting.

Noise control is a deliberate design point in the Brevida. The XS‑S seal works with a washable diffuser that muffles airflow noise and reduces drafts, which can disturb both the user and their partner. Combined with minimal facial contact and lightweight materials, the mask tends to feel less intrusive, and many users report the sensation of “barely wearing a mask”—provided the seal is fitted correctly. The pressure range of 4‑25 cm H₂O gives flexibility so it works across a wide spectrum of therapeutic settings, making it a versatile option for many CPAP users.

In practice, proper fitting is key. Because XS‑S is one of the smaller cushions, the straps of the headgear must be adjusted carefully—not too tight (which can cause discomfort, pressure, or air leaks), but tight enough to allow the AirPillow to inflate fully and maintain seal without gaps. Cleaning and maintenance also affect performance: over time, silicone cushions can degrade or lose their shape, which can lead to leaks. Regular inspection (every few weeks) and replacement when the seal becomes misshapen, torn, or compromised is important to preserve therapy efficacy and comfort.
