I am still learning best practices in this regard and have realized it’s a work in progress, at least for me. I am continually finding less than great things I am doing, my most recent example learning that keeping my Lifestraw pitcher by the kitchen sink with garbage disposal is not optimal placement. It seems obvious once someone mentions it, but this is all new to me and I find I have so many blind spots in terms of hygiene at this level. With that said, here is where I am at with storing my nebulizer equipment and Aerobika - I sterilize each day in my baby bottle sterilizer. Once sterilized and dry, I store in a plastic container for sterilized equipment only. I have different containers for different parts, and store by type, which is just an organizational preference. I have multiple sets of nebulizers and Aerobika should anything not dry fully in time for next treatment. In those instance where not fully dry, at times I place on paper towel, with another paper towel on top, and place in a kitchen cabinet to finish air drying. Once fully dry, gets stored in plastic box by type. Since I have upgraded my nebulizing equipment this happens rarely. I use plastic storage boxes from Container Store, their basic store brand, because they have lots of different sizes which I mix and match for my needs, larger ones for backstock, compressor and smaller ones for sterilized equipment, and they fit well, stacked in a deep kitchen cabinet next to where I do my AC (on opposite side of kitchen from sink, lol). I have not yet traveled with my equipment, so am interested on how others address that component.
