The Fisher & Paykel Nova Nasal CPAP Mask Diffuser is the key component behind the Nova Nasal’s whisper-quiet performance. Engineered with a unique diffuser system, it redirects and softens exhaled air to reduce noise and eliminate uncomfortable drafts so both you and your sleep partner can rest undisturbed through the night.
In an internal Fisher & Paykel validation trial, all 43 participants rated the Nova Nasal as “quiet” or “very quiet” while sleeping. The diffuser does not significantly change the overall airflow level from the mask, meaning the Nova Nasal can be used with or without the diffuser depending on your preference. This genuine Fisher & Paykel replacement part is conveniently washable, easy to attach and remove without tools, and should be replaced every 3 months for optimal performance.
