AI insight
Based on specifications & design characteristics

With the largest InfinitySeal size range in the ResMed lineup, the N20 is the safe first recommendation for new users who don't know their face shape well — 99% fit compatibility is more than marketing. Experienced users note the front-hose routing is the main reason they eventually move to the N30i, but for back sleepers it rarely matters.
