What This Component Is
The F&P Nova Nasal Diffuser Spare is a washable replacement part designed for the F&P Nova Nasal CPAP mask. It is part of the mask’s exhalation system and helps manage how air leaves the mask during therapy. It does not deliver pressure or change settings; it supports comfort and airflow control.
What It Does During Therapy
This diffuser disperses exhaled air to reduce noise and limit direct airflow toward the user or bed partner. By softening the air draft, it helps make CPAP therapy quieter and more comfortable, especially in shared sleeping environments. Its role is purely passive and focused on airflow dispersion.
Mask Compatibility
Compatible only with the F&P Nova Nasal mask system, including the Nova Nasal frame assembly. It is not compatible with other Fisher & Paykel masks such as Eson 2, Brevida, Evora, Solo, or any non-Nova models. Using it outside the Nova system is not supported by the manufacturer.
How It Attaches and Fits
The diffuser integrates directly into the Nova Nasal mask frame as part of the venting system. No tools or adjustments are required. It is designed to be removed and reinserted easily for routine cleaning or replacement as part of normal mask maintenance.
Care and Cleaning
The diffuser is washable and intended for repeated use. Clean it regularly using warm water and mild soap, rinse thoroughly, and allow it to air dry completely. Avoid bleach, alcohol-based cleaners, abrasive tools, or dishwashers, as these can damage the diffuser and affect performance. Follow the Nova Nasal use-and-care instructions.
Replacement Guidance
The manufacturer does not specify a fixed replacement interval. Replacement is recommended if the diffuser shows visible wear, becomes damaged, no longer cleans effectively, or if noise or air draft increases. Replacement timing depends on use patterns, cleaning habits, and overall condition.
Installation & Replacement
To replace the diffuser, remove the used diffuser from the Nova Nasal frame by gently pulling it away from the vent area. Align the new diffuser and press it into place until fully seated. Confirm it sits securely, then start therapy briefly to ensure airflow exits evenly and without obstruction.
