Is the water purifier useful? Xiaobian to tell you
As the saying goes: People take food as the sky, food as the water, and water as the net.
To this end, many families have installed water purifiers to protect their family’s drinking water. However, some people believe that the tap water in the home is qualified by the water treatment plant. If the water purifier is installed, it is a kind of repeated investment, which is unnecessary consumption.
First of all, let’s first understand the channels through which tap water may be polluted after leaving the factory.
The first is the water pipe network. The tap water is delivered to the user after long-distance transportation through the water supply network. However, for a long-term tap water pipeline, after a long period of use, it will inevitably cause aging corrosion problems, which will have a great impact on the water quality of the tap water, causing yellowing, sediment, rust and other pollution in the water quality of the user’s home. problem.
This is followed by pollution from secondary water towers and water tanks. If the water tanks of some high-rise communities are not cleaned for a long time, a large number of pollutants will be stored. Long-term accumulation will lead to heavy pollution of tap water, and the tap water delivered to each household will not meet the standard of direct drinking.
Speaking of this, the following small series teaches you a few simple ways to identify the water quality at home.
Identify the water quality at home
1, look at the water
Fill the water with a glass with high transparency, and see if there are suspended impurities and precipitated impurities in the water against the light. If there are impurities in the water, it means that the water quality is too bad to meet the drinking standard.
2, smell the water
After picking up the water in a glass, smell it. If you can smell the bleaching powder (chlorine), it means that the residual chlorine in the tap water is excessive.
3, taste the water
Tasting the boiled water, the taste of the mouth is awkward, indicating that the hardness of the water is too high.
4, look at the kettle
Look at the commonly used kettle in the house, is there a layer of yellow scale on the inner wall? If there is a description that the hardness of the water is too high (the calcium and magnesium salts are too high).
5, the water has a sticky feeling and is greasy
If the water body is found to have a certain viscosity, the specific performance is that there is a hanging wire when the faucet is closed, the chopsticks can be drawn, and the hand feels slippery when washing hands, indicating that the water body may be contaminated by organic matter.
The quality of water in daily life can be distinguished by the above five methods. What if there is pollution? Can the best price of water purifier be solved? I believe that many people have a little knowledge of the home water purifier.
Is there any use of water purifier?
The working principle of the water purifier is to purify the water layer by various levels of filter elements (such as PP cotton, activated carbon, reverse osmosis membrane, etc.) to achieve the purpose of removing impurities.
The water purifier is useless, there is a way to judge, according to the following four steps, you can intuitively feel the role of the water purifier.
1, observe the filter
When you change the filter, you will understand how much harmful substance it has helped you with;
2, sewage treatment
When you see if the discharged sewage is as clean as tap water, you will understand whether the water purifier is useful;
3, fan sound method
Take a glass of tap water and a cup of purified water and smell if there is any residual chlorine or other odors;
4, observe the faucet
After installing the water purifier, observe whether there are any foreign objects such as sediment and rust in the faucet.
Why do you need to change the filter regularly?
The filter element of the water purifier is like the “kidney” of the human body. The water quality of the water purifier does not depend on the quality of the filter element but also depends on whether the filter element is replaced in time. If the filter element is not replaced for a long time, it will cause water blockage, not only the water will become smaller, but the filtration effect will also change. Weak, so that the water passing through the water purifier will not be well purified, and the purity will naturally decrease.
It is worth noting that due to a large number of bacterial impurities in the filter element, the tap water will be subject to secondary pollution, resulting in water that is dirtier than the original tap water. Therefore, users must develop a good habit of regularly changing the filter.
Enjoy a happy life, health is fundamental
