I have a headache because there is too much aluminum in tap water there. What water purifier can be used to solve it?

The diameter of heavy metal ions is generally less than 1 nm, while the pore size of RO membrane is 0.000 1 micron, and that of ultrafiltration membrane is 0. 1 micron, so only RO membrane can remove heavy metal ions. Buy a water purifier. Don't worry, some people say that the water purifier removes all beneficial minerals. The minerals needed by human body mainly come from food, not water. Water only helps metabolism, just like some people lack calcium. The water purifier I used in Qinyuan is good. You can try. The human body cannot metabolize aluminum, and aluminum ions will accumulate in the cerebellum, which is easy to cause Alzheimer's disease. That's why you shouldn't eat more fried dough sticks, because there is alum in it, and alum contains aluminum.
