Fisher & Paykel Nova Micro —
Sizing, fit & care
Every cushion size ships in the box — try them in order and keep the one that seals. Below: step-by-step sizing, cleaning routine, and exactly when each part needs replacing.

How to size
- 1Open the box and find the labelled cushionsS, M, L are bagged separately.
- 2Fit the starting size firstConnect to your machine and lie down briefly to test the seal.
- 3Swap if it leaks or pinchesSwapping takes seconds — cushions click on and off the frame.
- 4Reorder your winning sizeWhen it's time to replace, you only need that one cushion.
Getting a good seal
A correct size plus light strap tension is the goal. Marks and leaks usually mean the cushion is the wrong size — not that you need to tighten more.
- Ships with all pillow sizes (S/M/L) — try each.
- The MicroPillows nestle in the nostrils and inflate to seal.

Cleaning & care
Quick daily wipe, gentle weekly wash. Avoid alcohol-based cleaners — they degrade silicone.
Replacement schedule
Cushion: about every 1 month. Headgear: every 6 months. Frame: every 6 months. Replace sooner if the cushion tears, hardens or won't seal. General guide only — follow your clinician/supplier advice.
