Is water purifier really useless? Why more and more families can't live without it?

Recently, the discussion of “water purifier is not effective” has created a wave of fever on the Internet. Some people say it is an IQ tax, but some people can not leave it, and even feel that without a water purifier will not be able to drink water. This contradictory voice so that many people still on the fence into a tangle: water purifier in the end is it worth buying? As a person who is very obsessive about the quality of life, I decided to do some research and then use my personal experience and some professional data to talk to you about this topic. If you are also hesitating to add a water purifier to your home, take a few minutes to read this article.

Water quality is more complex than we think, let's start with the tap water we drink every day. On the surface, tap water does look pretty clean, but really, it just looks that way. Although the city water supply system disinfects the tap water, disinfection does not solve all the problems. For example, when the tap water passes through the long transportation pipeline, it may come into contact with the aging and rusty pipe walls, and these rust debris and sediments may be mixed into the tap water. And, to ensure safety during transportation, a small amount of chlorine is usually added to tap water, and while chlorine can sterilize the water, the taste is a real headache.
Have you ever felt that tap water still has a strange odor after boiling? That's the residual chlorine at work. In addition, if you live in some of the more industrialized or agricultural pollution, underground infiltration (such as pesticide residues, heavy metals, etc.) can bring more serious hidden dangers than you think. The World Health Organization has previously stated that long-term consumption of unclean drinking water will increase the burden on the kidneys and may also lead to chronic diseases. If you don't believe me, you can check your local annual water supply quality report to see the indicators listed in detail, and then decide whether you need to pay attention to this problem.

What can a water purifier really do? What many people don't realize is that the water filters on the market are not “one size fits all”. Different types, different filtration technology varies greatly, some of the effect is indeed mediocre, but some can help us get rid of those invisible “drinking water trouble”. Currently the mainstream household water purifier is generally divided into the following categories:
-Ultra-filtration membrane type: this is a more basic model, can filter out sediment, rust, large particles of impurities and some bacteria. However, it is not capable of dissolved pollutants (such as heavy metals, pesticide residues).
-RO reverse osmosis type: this type is currently the most commonly used one, it through the high-precision reverse osmosis membrane, the diameter of the extremely small impurities (including heavy metals, bacteria, viruses, etc.) are intercepted, allowing only pure H₂O through. So some people jokingly say, with RO machine out is “pure to crazy” level of purity.
-Activated Carbon Filtration Type: Mainly used to adsorb odors, such as the unpleasant taste produced by residual chlorine. This type is usually used in conjunction with other technologies to make the overall effect more comprehensive. If you want to make an analogy, ultrafiltration membranes are like a dense mesh to sift out the big stuff, activated carbon is a “vacuum cleaner” to deal with odors, and RO reverse osmosis is like a small, super-discriminating inlet that lets in only the cleanest of small molecules.

Why are more and more people choosing to install them? I found that the people who are actually willing to buy a water purifier are roughly divided into two categories. One group is those who pursue quality life, they want every bite they take into their mouths to be healthy and high-class; the other group is compelled by real-life conditions, such as cloudy tap water at home, or living near an industrial area, which adds to the worry of drinking ordinary tap water for a long time.
To my actual experience, since the installation of the RO machine, I obviously feel the change - boiled water is much smoother, not before the strange smell, and will not appear before the common layer of “white floating matter”. Moreover, with these filtered pure water usually cook soup and rice, always feel that the original freshness of the ingredients is retained very well, that kind of light sweetness is really not a psychological effect. Another point worth mentioning is that, for some often takeaway milk tea but afraid of gaining weight partners, in fact, make their own milk tea or bubble tea, from the economic and health point of view are much more cost-effective. But the premise is that your tea/coffee brewing with a good quality of clean and softened cleaning materials, otherwise the most expensive brand-name tea leaves may be covered up the original flavor ~!

So, do all homes need to be fitted? It really depends on your actual needs and budget. If your home tap water usually tastes good, it does not seem to be impurities, then the installation of the basic model of ultra-filtration type of machine is enough; but if you are worried about the complexity of the problem of the water source, there are the elderly or children such as sensitive members of the body, then the investment in a high-performance RO reverse osmosis machine is definitely worthwhile. In addition, there are now some desktop portable small machines on the market, which are also suitable for short-term use by the rental party. Of course, before choosing, you'd better understand the local power supply, water pressure requirements and installation space, or spend money to buy back only to find that you can't use it, that would be too bad!

Tip: How to determine which one is right for you?
1. Look at the budget -- want to save money but solve the basic needs, you can choose the ultra-filtration type;
2. Look at the region -- if the environment in the region is complex, with RO will save a lot of heartache;
3. Look at the volume -- kitchen space is tight, choose a small desktop;
4. Look at the brand -- big brand after-sales service is guaranteed, to a certain extent, to avoid stepping on the mine.
Finally, remind everyone, no matter which one to choose, remember to regularly replace the filter oh! Again good machine, if lazy maintenance, is also a waste of money.
To summarize, more and more families rely on it nowadays, a big reason is not just out of convenience, but to really improve the quality of daily life. And to say it's completely useless? That only means that some people didn't pick the right product for them. So instead of arguing about whether it's true or not, why don't you try to choose it scientifically according to your family's needs, and maybe from now on, you'll be the one who can't live without it?
