What you are doing probably works fine. I use a mister too sometimes, especially in the nose. I also use a regular spray pump bottle at times to really irrigate the nasal cavaties.
The thing to keep in mind with sprays that are denser than you get with a nebulizer is that it can be dangerous to get too much liquid into a heavily congested chest. Since the silver I use (Advanced Colloidal Silver) has 150 times the surface area of say Sovereign Silver, I can use a nebulizer and get far more surface area of silver into my lungs than many would with a mister using average commercial products and much more still with most home generated silver.
As an aside, the debate on digestive enzymes becomes moot when inhaling directly into the lungs.
