Had we known that water purifiers should be chosen this way, we would never have stepped into those pits!

I don't know if you have such an experience: spent very expensive money to buy a water purifier, installed after not long, either the water output becomes smaller, or the filter element is always to be changed, and even there will be a strange smell. Every time you want to drink a mouthful of clean water, are skeptical - this money in the end to spend worth it? In fact, these “overturned” case is not uncommon, many of these problems stem from our lack of understanding of the water purifier, purchase stepped on the pit. Today's article is to help you avoid the pit and write. If I had known that the water purifier has so much to say, I would not have paid so much “IQ tax”! So, after carefully reading this article, you will certainly understand how to pick a really good, suitable for their own home water purifier.

Purification technology, in the end, which is reliable?

When it comes to water purifiers, our first concern must be its core - filtration technology. Currently on the market there are three main mainstream technologies: ultrafiltration, reverse osmosis (RO) and nanofiltration. But many people can not figure out the difference between them, it is easy to be fooled by some businessmen.

Ultrafiltration membrane pore size is relatively large, it can intercept the rust, sand, large particles of impurities, but dissolved in the water of heavy metals and bacteria and viruses can not help. So, if your tap water itself is of good quality and you only want to simply remove visible impurities, then ultrafiltration is almost enough. But if you are concerned about the safety of drinking water, such as lead, mercury and other heavy metal residues in the water, this time the reverse osmosis (RO) is really worth to start the choice. RO can basically be understood as “what all filtered out”, it is even the minerals are removed together. As for nanofiltration, it is between ultrafiltration and reverse osmosis, will retain some of the minerals that the human body needs, at the same time can filter out some of the heavy metals, is equivalent to a compromise program.

But then again, most families are still more recommended to choose RO machine directly. The reason is simple - safety first! Especially living in the industrial area near or underground pipe network is relatively old partners, with RO machine can be more assured to drink pure and healthy water. Of course, if you only use it for washing dishes and cooking, the budget is limited, then the ultra-filtration machine is not completely unable to consider.

Filter cartridge life span really affects the experience
I used to think that if I bought an expensive machine, I'd be fine, but then I realized that not looking at the life of the filter cartridge can be a big pitfall. Some cheap machines although buy when spend less money, but the cartridge two or three months to change once, each time to change a few hundred dollars, add up to more expensive than buying a machine!

So when picking a water purifier, be sure to look at the service life of different levels of cartridges, as well as the cost of late replacement. Some high-end models will be designed to graded cartridge, such as the front PP cotton specializing in intercepting sand, rust and other large particles, to protect the follow-up core filter layer; activated carbon for adsorption of odors; and finally by the RO membrane for depth filtration. This design not only improves the overall filtration effect, but also extends the life of core components (such as RO membrane).

In addition, many intelligent water purifiers are now equipped with a cartridge reminder function, you can real-time monitoring of the status of the cartridge at all levels, when it is necessary to replace the automatic alarm prompts, no longer have to worry about forgetting to change the problems caused by. This kind of thoughtful design although the price is a little higher, but from the point of view of long-term cost of use, in fact, more cost-effective.

Wastewater? Don't panic, it's important to look at the ratio!
Anyone who has bought a reverse osmosis machine may have heard the term “wastewater ratio”. The so-called wastewater is the concentrated water discharged by the machine when making pure drinking water. Some people feel that this wastewater is particularly wasteful, in fact, there is no need to be too entangled, because the waste out of the not really “dirty”, but contains a high concentration of minerals and impurities in the concentrated liquid, can be utilized twice, such as used to mop the floor, flush the toilet and so on. In addition, the new models now on the market have been significantly optimized waste water balance, some models have even reached 1:1 or even 1:0.5 (i.e., for every 1 liter of pure drinking water production, only 0.5 liters of concentrated water discharge). Try to prioritize these low wastewater balance products when choosing, not only environmental protection, but also more money!

Undercounter or Overcounter?
Space determines everything Many people have no concept of what style is suitable for the home before installation, looking at the advertising map is beautiful just buy home, the results found that it can not be installed ...... is not very heartbreaking? In fact, the mainstream style is now divided into two types of kitchen and countertop. Kitchen under the general need to reserve cabinet space, and perforated to install an independent faucet, this design is beautiful and invisible, very suitable for families with large kitchen areas. The countertop type does not require complex installation, only need to access the water pipe can be used, very convenient for rental party or small family. However, the disadvantage is that it takes up a certain amount of countertop space and may not look as neat and sharp as the undercounter model. Therefore, before picking a model must be based on the actual situation of their own homes to measure the size, ask for specific installation requirements, or when the return trouble, not to mention the possibility of delaying the schedule.

Limited budget?
Don't be gimmicky features confused Finally, I would like to remind you of one thing: don't be those who seem high-tech, but in fact there is no need to confuse the small features. For example, some brands promote what “oxygen activation” “magnetization activity” and other new concepts that sound mysterious God, but in fact, to improve the safety of drinking almost no help, it is completely marketing tools. If you have a limited budget, why don't you focus on the basic performance, such as the stability of the quality of the product, whether the after-sales service is perfect, etc., instead of blindly pursuing the so-called black technology.

Through today's article, I believe you have a certain understanding of how to correctly choose the right water purifier for yourself. If you are confused about how to choose, I hope the tips mentioned here can provide you with some reference. No matter what, “healthy drinking” is always our highest priority, so don't be greedy for cheap or the pursuit of appearance and ignore the really important safety performance  ~!
