how to choose water purifier

How to choose water purifier for home

Everyone should know about water purifiers. As more and more people are realizing the importance of safe drinking water, many families choose to install water purifiers, hoping to protect their families through water purifiers, but there are many kinds of water purifiers on the market, the functions and uses are different, so how can I choose the one that suits my home? According to a master who has been working in water purifiers for more than 20 years. He said that it is enough to know the 5 things. It is very simple. The words of the master are repeated below. If you are going to install water purifiers you should take a look. ~

1.Understand the filtration principle of water purifier

The principle of water filter is actually very simple. It is filtering layer after layer to remove the sediment, residual chlorine and heavy metals in the tap water one by one. If you want to choose a suitable water purifier, you must first understand Its filter element, generally speaking, the filter element of the water purifier is composed of various membranes. PP cotton and activated carbon are the first steps of filtration. Almost every water purifier has these two filtration steps!

①PP cotton

PP cotton is generally placed in the first layer of filtration, the main function is to filter out large particles of impurities in the tap water!

②activated carbon

Activated carbon is actually black granular carbon, which has the functions of adsorption, decontamination, decolorization, filtration and purification. It has a strong adsorption capacity, and many also put it in the refrigerator or wardrobe! Basically, water purifiers will be equipped with activated carbon front and rear activated carbon filter elements. The activated carbon particles in the front are larger, which are used to adsorb impurities, odors, residual chlorine and other harmful substances in the water. The rear is generally used to improve the taste. !

Although PP cotton and activated carbon are necessary for water purifiers, their filtering capacity is very limited, and the filtration effect of a water purifier is really determined by ultrafiltration membranes and RO reverse osmosis membranes!

③ultrafiltration membrane

The ultrafiltration membrane has a filtration accuracy of 0.01 microns, which can filter out bacteria, algae and other macromolecular pollutants, but it cannot filter metal ions, so it is not pure water. It can be used for bathing, washing clothes, etc., for a long time. There will be scale production!

④ RO reverse osmosis membrane

First of all,we need to know how does reverse osmosis work. RO reverse osmosis membrane is the best grade of water purifier, with a filtration accuracy of 0.0001 micron, which can basically block all impurities and heavy metals. The water obtained is pure water and can be drunk directly. Many people say purified water. The filter will filter out a lot of minerals in the human body and cause the human body to lack nutrients. In fact, the content of minerals in the water is very small. Drinking 10 barrels of water is better than eating an apple!

2.Choose the bucket or no bucket properly

In fact, RO reverse osmosis water purifiers are divided into buckets and non-buckets. A bucket is suitable for friends who are often at home. You can use it whenever you want. Friends who are not often at home suggest to choose bucketless, because those with buckets often don’t use them. The water will go bad, and the bucketless water purifier is more convenient and practical!

3.choose an energized RO reverse osmosis water purifier

In fact, not all water purifiers need to be energized. For example, ultrafiltration and microfiltration do not need to be energized, but the filtration accuracy is not enough. Some small particles cannot be completely removed. It is best if you want cleaner water. Choose the energized RO reverse osmosis water purifier, you can drink it directly!

4. Replace the filter element frequently according to the actual situation

The purification capacity of the water purifier is limited, and the filter element needs to be replaced regularly. The replacement period is generally indicated at the time of purchase, but this is for reference only, and it must be determined according to the difference in water quality and water consumption, so this is still based on Choose according to your own situation!

 How to distinguish when to change water filter?

① The water output of the water purifier becomes smaller;

② The taste of the water is similar to that of tap water, it is time to change the core at this time!
