I brought a whole box with me but haven't used much. I bet you could find them on Taobao.
Yeah you're supposed to use distilled water from what I've read. In rare cases, people have used tap water and it's lead to brain infections. Sounds crazy I know but I guess I'm just a little sketched after reading that.
Hell no, I would never use China's tap water to irrigate my sinuses lol. Brain infections sounds awful. Holy crap.
Lol no these were cases back in Canada and the States where tap water is relatively healthy. The articles I read just said something along the lines that our stomach has acid that can kill bacteria and organisms in water but our nose obviously doesn't. Even the filtered water here can be a little suspect so I figure it's better to be cautious.
Alright, good looking out!
