The participant will be randomised to use either full face mask prototype 1 or 2 as according to the randomization log for 7 ± 3 days in home. The participant will then crossover to the other full face mask prototype to use in home for 7 ± 3 days. Neither the investigators or the participants will be blinded to the study.
