I am a doctor, an MD. DO NOT DO THIS UNLESS YOU USE STERILE WATER! Think your tap water is clean enough? Think Flint, Michigan. There are thousands of cases of neti pot induced infections and yes from tap water. The technique is not bad practice, just use STERILE WATER. You can actually buy STERILE SALINE at your drug store that has the salt already mixed in at the appropriate concentration. Please use ONLY STERILE WATER in a neti pot or any device for nasal lavage.
