The first time anyone considers cleaning their personal filter, the overall message is:
Read the instructions in full before using
Start with isotonic
Ensure a good seal with bottle tip and nostril
Confirm bottle is in the correct position by double-checking the water lines
Flush gently, listening to your body
Forcefully breathe out thru both nostrils while the mouth is closed
Repeat on another side
Once you have mastered the technique, increase the salt concentration for best results.
We have found simply ‘holding your breath’ while flushing prevents any solution from draining down the back of the throat.
