I love my neti pot, it's saved me (and the entire fam) many $$ in doc visits with our seasonal allergies , also has helped keep cold viruses manageable (as well as religiously using zinc gluconate at the first sign of sniffles) in our home during those seasons.
When I was younger I used to do the salt water snorting up one nostril and then the next, the neti pot makes it much easier.
I know it may sound gross to use a neti pot, but since I got everyone here using it we hardly ever get sinus infections or throat infections from viruses or allergies, and the duration/severity of rhino type viruses has been cut down by at least 50% for us.
Ours is cheapo plastic deal I found at some grocery store a few years back, I think it cost less than $15, I do remember Walgreens having a BOGO deal that I missed out on several years ago, watch this winter for those type of sales. We only have one neti pot, but if I could find them at great prices, I would insist we all have our own indy ones. If you only have one per fam, hot soapy water and/or peroxide are good sanitizers)
You *can* do the same thing w/a shot glass of salt water (I did that for decades) , but the neti pot makes it much easier, and whether they are plastic or ceramic, they can be sanitized in a dishwater or even in hot soapy water in the sink..
