Diffuser for Nova Nasal Mask

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.

• Noise Reduction — Diffuses exhaled air to significantly minimize sound during CPAP therapy; in an internal Fisher & Paykel validation trial, all 43 participants rated the Nova Nasal as "quiet" or "very quiet" while sleeping
• Draft Minimization — Redirects airflow away from you and your sleep partner for a more comfortable sleep environment
• Optional Use — The mask can be used with or without the diffuser, as it does not significantly affect overall airflow levels
• Conveniently Washable — Designed to be cleaned regularly with mild soap and lukewarm water, then air dried; clean weekly for best performance
• Easy to Attach & Remove — Simple to disassemble for cleaning or replacement with no tools required
• Nova Nasal Exclusive — Compatible exclusively with the Fisher & Paykel Nova Nasal CPAP Mask (Model #400NVN151)
• Replace Every 3 Months — Should be replaced every 3 months, or sooner if discoloration, damage, or reduced performance is noticed
• FSA/HSA Eligible — Qualifies for purchase using Flexible Spending Account or Health Savings Account funds
