The diffuser on a mask eventually becomes clogged, and the exhaled breath becomes louder and more direct. Zest Q diffuser filters replace this worn part and restore a well-diffused breath from the nasal mask outlet.

• Exhaled air disperses instead of coming out in a jet, meaning less draft towards the person next to you
• The filter slides into its housing in seconds, no tools or strap readjustment required
• Genuine Fisher & Paykel part, precisely sized for the Zest Q housing

These filters are suitable for the Fisher & Paykel Zest Q nasal mask.
