The stainless steel 500ml neti pot is large enough to rinse both nostrils in a single fill. The tapered nose tip gives a comfortable snug fit.
To use:
Combine warm water and pure non iodised salt (5g/100ml)
Over the sink, place the tip into one nostril to create a snug seal
Tilt head forward and pour solution into nostril, and expect it to exit through the other nostril.
Repeat for the other nostril.
