Don’t use unsterilized tap water to rinse your sinuses. It may carry brain-eating amoebas

I think Kurzgesagt made a video about how these guys sneak into the brain, they follow the olfactory nerve I believe. They didn't evolve to eat brains, it's just an unhappy coincidence.
I rinse my sinuses with water from my RO system. My well produces barely-drinkable water, so it takes two membrane passes to knock the minerals back. Ain't nothing getting through that, by the time it's in the product tank it's around 5ppm TDS and I have to run it through calcite to add enough solute back to drink it.
If you're really concerned a cheap single pass RO would be more than adequate for town water but make sure you have a carbon prefilter, chlorine eats up the membranes.
well I put two packets of salt in about a glass of water which is about %1.5 salinity level. studies have shown that above this level the mf is basically non viable:
"Salinity exhibited a significant effect on the growth of N. fowleri in both dH2O and environmental water. In general, increasing salinity concentrations decreased growth but significance differences stopped once salinity reached 1.5% NaCl. This likely occurred because growth and replication of N. fowleri were minimal past this salinity level, with the amoeba encysting at salinity concentrations above 1.5% and ultimately losing viability"
between high salinity, chlorine in the water and my super mucus filled nostrils, I hope I am fine.
