Each treatment only takes 4-5 minutes. My nasal allergy sypmtoms are relatively mild, so each treatment usually keeps my sinus' clear most of tne day or evening. What I appreciate is no longer having to deal with the side effects of allergy medications. For more severe sinus allergy symptoms, more frequent treatments, or simply used as an adjunct to taking allergy medications may be required. Considering it's relatively cheap $15 price, I think it's well worth giving the Neti Pot a try. I'm certainly glad I did.
