Water purifier is not the more expensive the better! Teach you to look at these 4 parameters, don't be fooled again~!
Should I buy a water purifier? Is not the higher the price, the more features means better? In fact, this inside the “pit” really quite a lot! Today we will talk about those key points that must be concerned when buying a water purifier. Don't let your wallet shrink in vain, but also can't drink healthy water!

First of all, to be honest, now on the market water purifier model is really fancy, let a person to pick. Some claim to be able to filter 99.999% bacteria, some focus on mineral retention, there are direct tens of thousands of dollars a ...... But I want to say - not all expensive machines are suitable for you, and even some high-priced products, not as practical as a few hundred dollars of niche brands! ! So what do we really think? Listen down ha, I use my own experience to give you a run through.
First of all, you have to know that the water purifier is really important to the “core parameters”, which directly determines whether it can guard your drinking safety. The most common on the market is also the most easily ignored, is the following four:
1. Filter type and number of levels

We have not found that the same called “water purifier”, some grow fat, some small and exquisite, in fact, this is the main difference in the cartridge. Common cartridge PP cotton, activated carbon, ultrafiltration membrane, RO reverse osmosis of these kinds, each role is very different!
-PP cotton is responsible for intercepting large particles of impurities, such as sediment, rust;
-Activated carbon can adsorb foreign colors and odors, but also filter some of the residual chlorine;
-Ultra-filtration membrane can further remove bacterial impurities, but can do nothing about dissolved solids;
-RO reverse osmosis is the real sense of deep purification, even heavy metals can be dealt with.
Generally speaking, the more stages indicate a more detailed filtration process. But it does not mean that 7 levels must be stronger than 5 levels, the key is still to see what materials are used in each level. If all the cheap materials pile out, it is likely that the effect is not as reliable as the combination of three or four levels. When you choose to see clearly the main filter configuration, do not understand can directly ask customer service: “The main filter is which category?”
2. Rated water output and flow rate

Many people find a pain point after installing a water purifier - water like a snail, a pot of water to catch half a day is not full. In fact, this is because different models of rated water output and flow rate design is not the same. If the family has a large number of people or the kitchen water consumption, must give priority to the label “large flow” of the product, or you will be every day doubt life. Another point, often people think that RO purification is the best, but in fact the RO membrane on the tap water pressure requirements are very high, if the home itself is not enough pressure, you need to hang the external booster pump, otherwise not much pure water. Before purchasing, ask about the speed of water (L/min) and the daily supply capacity (L / d), home users are recommended to choose ≥ 400 gallons / day large capacity models ~
3. net waste ratio

This term sounds quite mysterious at first glance, in fact, it refers to the generation of 1 liter of pure drinking water, to waste how much waste concentrated water. Some older RO machines can drain a kitchen floor drain like rain in an hour. Newer water-saving machines usually do 1:1 or even less, while obsolete models may be 1:4 or more, which means that for every cup of pure, good water you drink, you pour out 4 cups of waste at the same time. This is not only wasteful, but also hurts the environment and your wallet! Try to choose a new model with a “low waste ratio” or water-saving balance technology, which is friendly to the environment and saves money.
4. Maintenance costs & after-sales service

Many friends only focus on the price tag when buying, but ignored the money to change the cartridge later. A cheap machine, if three months to change a valuable filter, compared to slightly more expensive but only once a year to change the big brand machine, in fact, the long-term calculation is much more cost-effective. And big brands are usually perfect after-sales, small brands out of the problem no one repair, that can really want to cry. So don't just look at the down payment price, but think about the maintenance budget! Before you get one, ask how often the official recommendation is to change the various types of filters, and how much the cost of a single time; try to pick a big brand with a nationwide warranty or city outlets to support ~!
Speaking of which, do you think you have become half an insider? In fact, most shoppers will not take the initiative to tell you this knowledge. But as long as you remember - the core parameters are always more important than fancy advertising, it is not so easy to be set! Finally, a nagging word, different areas of tap water pollution varies greatly, if possible, it is best to bring their own original tap water to test to see how heavy metals, chlorine, microbial indicators, and then decide whether you need RO depth filtration or ordinary ultra-filtration is enough. After all, only suitable for their own is really good ~
