How many times a day to irrigate?
If you are not having symptoms don't irrigate. You remove Lysozyme and other
products that the body uses.
An exception is during allergy season when you want to remove pollen and IgE
from the nose or
if you are susceptable to catching colds, and everyone around you has a cold,
and you want to remove the ICAM 1 from your nose to help prevent catching a
cold.
Once your nose is normal, you don't need to be more normal.
When you use pulsatile irrigation or Hydro Pulse irrigation, there is a much
more effective removal of nasal mucus. You do get much more of the associated
bacteria out, but  irrigating excessively can remove the needed lysozyme too.
Therefore the "rules" of how much to irrigate are different for Hydro Pulse vs
Pots, etc. because more comes out with the former method.

Not for me.  When I get a severe sinus infection, I get floods of
purulent drainage.  I find that I can irrigate every *two hours* and
still find lots of purulent drainage coming out.
