The Nova Nasal diffuser from CPAP Supplies Canada is the washable exhaust vent for the Fisher and Paykel Nova Nasal mask. It softens and spreads the air you breathe out, which cuts noise and stops a stream of air from reaching the person beside you. Over time the diffuser gets dirty and less effective, so a fresh one keeps therapy quiet.

Why choose the Nova Nasal diffuser?

• Quieter nights. The diffuser breaks up exhaled air so the vent stays soft and low in noise.
• No draft on your partner. It directs air away instead of blowing a jet toward the other side of the bed.
• Washable and reusable. Rinse it clean rather than tossing a disposable every few days.
• Genuine Nova Nasal part. Made for the Fisher and Paykel Nova Nasal frame for a proper fit.

Cleaning and replacement

Rinse the diffuser about once a week in warm water to clear buildup that can make the mask louder. Even with regular cleaning, plan to replace it every one to three months, or sooner if it looks dirty or the vent noise creeps up.

Frequently asked questions

Is this a filter for the air I breathe in?
No. The diffuser sits at the exhaust vent and manages the air you breathe out, keeping it quiet and gentle. It does not filter incoming air.

Does it fit the Nova Micro?
No. This diffuser is specific to the Fisher and Paykel Nova Nasal mask, not the Nova Micro pillow mask.
