Yeah; my doctor recommends neilmed sinus rinse, in the little squirt bottle and powder packet form factor. I keep a gallon of distilled water in the bathroom. Problem solved. (Avoid the maximum strength formulation unless you want to use osmotic pressure to reduce swelling — ouch!)

If you go for the carbonated mist spray stuff, note that you get a lot less volume of water per dose, so it’s a bit less reliable (but much more convenient since you don’t need to worry about sterilizing anything).

Regarding the article: Unless you’re using this when completely symptom free (or have some condition where your sinuses are chronically dry), there’s probably already more crap in your sinuses than you need. I’m skeptical of this new technology.
