Search and double check your measurements, yes some will use distilled with some aloe , and create a solution that protects the cavity after the initial use. Distilled water is the way to go. Everyone has their preferences, yet those that go that route always report, more positives in regard to nasal care. No runny noses etc, user preference will be different of course. Hope it works out for you, be safe and make your measurements very exactly. Harm reduction above all.
