The Diffuser for Brevida Nasal Pillow CPAP Mask is a replacement cap filter that serves dual purposes: it traps fine particles from exhaled air and diffuses the sound of air being released during therapy. The result is quieter exhalation and reduced air draft toward your bed partner.
The diffuser attaches to the elbow of the Brevida Nasal Pillow CPAP Mask and is designed as a washable, reusable component. Over time, the filter material can become dirty or lose effectiveness, at which point replacement restores optimal performance. This is the diffuser cap only and does not include the mask elbow or any other mask components.
Note: This is the diffuser cap only. The Brevida mask elbow, frame, cushion, headgear, and short tube are sold separately.
Dual-Purpose Filtration — Traps fine particles from exhaled air while simultaneously diffusing the sound of airflow for quieter therapy.
Quieter Exhalation — The filter material breaks up the exhaled air stream into a softer, more dispersed flow, reducing noise and draft.
Washable & Reusable — Can be cleaned weekly with mild soap and warm water to extend its useful life before replacement is needed.
Snap-On Attachment — Attaches to the top of the Brevida mask elbow for quick, tool-free installation and replacement.

When to Replace:
Do Not:
The diffuser breaks up exhaled air into a gentle, dispersed flow rather than a focused jet. Less noise from the exhalation port means fewer nighttime disturbances for everyone in the room.
Beyond sound reduction, the filter material captures fine particles from exhaled air, contributing to a cleaner sleep environment and fresher-feeling therapy.
Weekly washing extends the diffuser’s life significantly. When the filter finally shows visible discoloration or the cap won’t stay attached, a fresh replacement restores full performance instantly.
