I used to have a household water purifier, the kind that I drank directly, but I needed to change the filter element frequently and occasionally! Later, the year before last! So I took it apart. I'll boil hot water! I live in Beijing, and people who live in Beijing all the year round should know the scale, regardless of the quality of drinking water in Beijing. When you boil the kettle, there is a big layer of scale at the bottom!
Besides, the tap water in Beijing smells, so I can't drink it any more. But a friend from Hebei came to my house for a few days last year. He drank tap water directly once, and then asked me, does Beijing's water stink to you?
His family is in the countryside, and he built his own small building. Then he dug a well in the yard, and the well water entered the high-pressure tank in the building through the pump, and then supplied water to Xiaoyanglou!
Moreover, my friends and people there often get water to drink just by turning on the tap! Nobody has a water purifier! I also drink cold water directly when I go to his house. To tell the truth, the water is slightly sweet!
When he asked me, I remembered that when I first arrived in Beijing, the economic conditions were not good, and I often drank tap water directly. At that time, I obviously felt the strong smell of disinfectant! But now I can't drink. I must get used to it!
After the water purifier was installed in my house, when the master who changed the filter came to the door for service, I asked him what to do with the replaced filter. He replied, just go downstairs and throw the trash can for a while!
At that time, I had a feeling of self-inflicted! Because we bought a water dispenser to drink clean water, but the filter element replaced by the water dispenser was thrown away directly. Not only does it create garbage, but if it rains again, it will pollute the groundwater, and the water quality will be bad then. If the water quality is not good, more people will buy water purifiers, and then more garbage will be produced ... this is an infinite cycle!
The water purifier does have an effect on purifying water, but ... I hope that one day in the future, when we don't need a water purifier, we can also drink water boldly!
The second point of view
According to my experience, water purifiers should be installed, especially in old communities. Even if a water purifier is installed, try not to drink raw water, because the water quality may meet the standard, but can the "pipeline" meet the hygiene and safety standards? Of course, people who have always been used to drinking raw water have no problem. When we were in the countryside, we drank ditch water and mountain spring water, and seldom had diarrhea. After all, strong physical labor will sweat a lot and detoxify.
