I do not know either, I should ask. We have the water tested annually. A neighbor had e coli, which encouraged us to get the UV filter.

A quick google search (probably a popular search this morning): “UV is very effective in killing Naegleria fowleri bacteria, as well as all other bacteria.”

All of these nasal wash tools say to not use tap water. Instead they have sterilized water with buffers to be used.
