AI insight
Based on specifications & design characteristics

The F20 is ResMed's highest-volume full face — InfinitySeal is engineered to fit 97% of face shapes without custom sizing, which is why it's the most commonly prescribed starter full-face mask. Front hose routing is its main limitation for active sleepers, but for back sleepers it's the first recommendation from most sleep therapists.
