Micro-Filtered Nasal Wash System “Squeeze Bottle”
Important: If more than one family member needs to use nasal saline, each person should use
their own bottle. This will prevent spreading germs between family members.
How does it work?
1. Pour the contents of the saline
packet into the bottle. First –time
users should start with 1 packet to
make an isotonic solution. As you
become more used to using the
system, you may work up to using 2
full packets for a hypertonic solution.
2. Fill the bottle with warm tap water to
the 8 oz mark on the bottle. Test the
water temperature before using.
3. Put the cap back on the bottle and
tighten. Gently shake the bottle until
the saline is dissolved.
4. Turn the bottle upside down so the
comfort tip is facing up. Lean over
the sink with your head bent down so

the comfort tip up to your right
nostril and gently insert the tip so
that it forms a comfortable seal. Aim

nostril and then exhale through both
of your nostrils to clean them of
excess mucus and solution. Gently
blow your nose into a tissue.
8. Repeat the procedure on your left
nostril with the rest of the solution.
9. When you are done hold the system
upside down over the sink and
squeeze a few times to clear the
solution still in the cap.
10. Holding the cap assembly over the
sink unscrew the filter by turning the
white ring on the bottom of the cap
counter clockwise while holding the
cap. Empty any solution that is left
into the sink. Reassemble the filter
making sure the black o-ring is
seated above the filter base threads.
