I irrigate daily, and I haven't caught the flu in years.  Probably
because I get a flu shot every year.

Do you mean last year or this? I have been doing daily's for a couple of
years now and haven't had the flu nor do I get the shot even though my doc
suggests it. I do get a touch of a cold with sore throat though and end up
using the nebulizer and prednisone though. I wonder how many using
irrigation are finding they don't get as sick...this will be interesting.

I irrigate a lot, have done so daily for years, and have caught the flu
before while irrigating. Right now I have a cold, in fact, that I have had
for about 3 or 4 weeks. I used to get a lot of sinus infections too,
including while irrigating daily, but I think that has improved since my
last surgery.

I'm one of the fortunate persons who had a flu shot for this season (last
Monday), so hopefully I won't get the flu this year, although of course it
does not provide perfect protection.

Of course, it is not always clear what is meant by "the flu". Literally the
word is short for influenza, and that is what the flu shot protects against.
But many people say they have "the flu" when they have a bad cold. So,
having people answer a question about "the flu" is not really clear,
regarding what they had.

Are you hoping to promote your device as a replacement for flu shots, since
they are in short supply?
