My daughter gave me this himalayan Institute Orginal Neti Pot complete Sinus Cleansing System I think in November. I had never really considered anything like this before. I usually get a sinus infection every winter reguardless of what I do to prevent them. My daughter said use it daily which I started out doing. I ran out of distilled water and could never remember to get any. Well I got the sinus infection,my daughter fussed at me because I had not been using the Neti Pot. I went to the doctor and she put me on medication. I told my doctor about having the Neti Pot and she ask why I had not been using it. She said that it was one of the best things on the market to help prevent sinus infections and to start back using it when I got home. She told me it would help me to get over my sinus infection a lot quicker and would help to clear my clogged sinus so that I would not feel like my head was full. I highly recommend this. I use it in the shower.
