would a respiratory therapist or someone with any ideas please tell me a little more about nebulizer mouth pieces. i got my 1st nebulizer in 2018 and they dropped it off and said goodbye. i am currently using it 2 to 3 times a day with a duo neb and 2 times a day for sodium chloride with a t type mouthpiece and i am using the same ones i have had for the past 2 - 3 years. i notice there are other types out there called 'side stream' and wondered about them. i don't want disposables and i don't use a mask.
