I have a chlorine filter, brings the ppm from 580 to 90. I didn't buy the r/o filter this time so it's 1 step below it. That's what my family drinks + all the pets in our house.

But tap is fine. If the city your in deems your municipal water safe to drink, then it's safe for your snakes.

The only thing I would worry is if you had well water with poor or no filtration.
