Re-read the nebulizer stuff. I have nothing bad to say about distilled water, but Dr Brownstein says the saline helps. (Also recommends including Lugol's iodine, but I have no experience with that.)
Easy-peasy: "wound care wash" saline solution from the first aid section, it's sterile and kept in a pressurized can so everything you don't use is preserved without refrigeration. You can also easily and accurately measure the peroxide with a (no prescription required) diabetic syringe, where each unit marking = 0.01 ml. I used 5ml saline using the rough measurements on the nebulizer cup, and 3 "units" of hydrogen peroxide, slightly higher concentration than Brownstein's dilution, but way lower than Mercola's.
Diabetic insulin syringes are sold in packs of 10, in sizes of 100, 50, and 25 units. 25 is easiest to read, 50 is still pretty easy and the size is more common. Back in the 80's when gov't was worried about easy access to needles, they required pharmacies to keep a log, so you may have to sign for them. On the other hand, they also made it illegal to ask for a prescription before dispensing, so diabetics wouldn't be stranded without a clean syringe. It really is a lot easier than making a big batch and keeping it in the fridge, and you will have safe, consistent measurements. You can re-use the syringes, since they're only transporting disinfectant.
