We got a $150 reverse osmosis system a little over a year ago. It’s a lot cheaper than bottled water and better than most.
The fridge at the new domicile has an RO filter.
It makes a huge difference. I changed the filter out not long after moving in. An alert came up.
The old filter weighed a pound or so. New filter and box, feather light.
Does reverse osmosis remove flouride?
People are not anti city water. The city spends mega dollars to clean up water. The ruins the water with flouride.
Losers.
No commune will ever agree on what is healthy. City taxes are lost money.
