You could always stop drinking and stop breathing. However, it does not seem to be an option. Water can be filtered to take out some of the impurities, but we all have to breathe. Stay healthy, eat healthy food and plenty of exercise.

With the growing pollution, especially water pollution, people's health is threatened. How to protect you and your family? Do you think about this problem?

It is possible to solve this problem and I had almost finished writing a rather lengthy explanation regarding how you could do that, but "the Grinch stole it" (I accidently erased it), and frankly, I'm too lazy to write it again.
The bottom line is really that while technically it is possible to achieve your goal, the cost is rather prohibitive. You would have to be an exceptionally good business person to be able to pay for that.
But cheer up, you are not the only one who can't afford that. I have the knowledge, but also don't have those millions to spend on such a system...
