Problems that occur with reverse osmosis

These days attaching a filter to your water tap is becoming the norm because as most people know, tap water is far from perfectly filtered. In alot of ways it is not very healthy to drink, but nobody has time to boil and prepare their water before drinking it. Filters have become pretty sophisticated lately and can purify the water right out of the faucet on the fly. The disadvantages of reverse osmosis, a process some filters use to do this, is that it could take out too much of the things we actually need in our water such as minerals our body needs to stay healthy.
