Yes, the Pari E flow can be used with 7% saline. It does not clog up. After each use, I soak it in very hot tapwater with a drop of Dawn dishwashing liquid. After 10 minutes I rinse it in running hot tapwater and put it on the counter to dry. About every other day, I pop it into the baby bottle sterilizer. I do not boil it on a regular basis, but will boil it when I come home after a trip. After about a year and a half I replaced the handset. Long story. Our hot water heater was going and the rust from the water basically ruined the mesh disc, which was ready to be replaced anyway. I purchased the easy care cleaner and have never used it. Not necessary if you have a baby bottle sterilizer. The Aerobika was not very effective for me so unless I’m desperate, I don’t use it. I simply use autogenic drainage after the nebulizer.
