I live in EU and bought from the US SinuPulse Elite, so I spent a little fortune on it. It was advertised as the best in class. It's definitely safe as the pressure is just enough, but it did not help at all for my problem. Most of the EU irrigation systems turn it up to 11 when it comes to pressure. I don't think that's safe.

Anyway, I think I just have chronic inflammation.

It's not allergy either.
