Oh interesting. So gravity filters don't require changing filters?
They do need changing. The main selling point of gravity filters is they don't require electricity.
Gravity filters have different properties. It depends on the manufacturer and what they're designed for.
Ah ok. So basically, something like a brita filter, but can be much larger for better filtering.
RO doesnt use power either but it wastes a lot of water, and yea, looks like it still leaves some fluoride in the water
