AI insight
Based on specifications & design characteristics

17 dB is the quietest full-face rating in this catalog — achieved through a circular diffuser that physically redirects exhaled air rather than venting it forward. Owners with sensitive bed partners cite this specifically as the purchase driver; the under-nose cushion that reduces the boxed-in feeling is an added benefit.
