How to choose a water purifier?

If you want to buy a water purifier, but you don't know much about the water purifier, don't know how to choose? Today, we summed up a set of strategies for beginners to buy water purifiers, teaching you how to choose water purifiers.

1:Select the model by water quality

The water purifier under the kitchen is most commonly used in life, and there are generally two kinds of water purifiers under the kitchen, namely ultrafiltration and reverse osmosis. Ultrafiltration is suitable for areas with good water quality, which can retain minerals, but cannot filter heavy metals. Reverse osmosis can filter almost any impurities except water, with the highest filtration accuracy, and is suitable for areas that are easily polluted or have unstable water quality.

2:Filter Cartridge

The filter cartridge determines the type of water purifier and is the core component of the water purifier. Its quality directly determines the filtering effect, not the more the better. At present, reverse osmosis membrane/ultrafiltration membrane is the main filter element widely used in the market, together with PP cotton, activated carbon, composite filter and mineralized filter element.

1: PP cotton filter: it is used to filter large particles such as sediment, rust and eggs in water.

2:Activated carbon: filter the odor, residual chlorine and organic matter in water to improve the taste of water.

3:Ultrafiltration membrane: it can filter out tiny suspended matter, bacteria, organic matter, etc., and can retain minerals in water.

4:Reverse osmosis filter: it can filter almost any impurities outside the effluent, such as bacteria, viruses, heavy metals, etc., and the effluent reaches the standard of direct drinking.

5:Mineralized filter: supplement the trace elements needed by human body.

6:Composite filter: several kinds of filter elements with independent functions are scientifically assembled on one filter element as required, and at the same time, their functions are brought into play.

In addition, the average service life of the water purifier is 5-10 years, and the cost of replacing the filter element for a long time is also a factor to be considered. Choosing a water purifier with lower core replacement cost can reduce the later cost.

3.Water Flow Rate:The greater the machine flux, the faster the water outlet speed. For families with large water consumption and fast water outlet, the water purifier above 800G is the first choice.

400G is suitable for 3-4 people, and the flow rate is about 1.05L/min.

600G is suitable for 6-7 people, and the flow rate is about 1.58L/min.

800G and above are suitable for families with large family population and need to get water quickly, and the flow rate is above 2L/min.

4.Material:The water-contacting parts of the water purifier must be food-grade raw materials, which are corrosion-resistant and free from harmful substances. For example, bisphenol A is a common organic chemical raw material, but it is also a low toxic chemical, which is harmful to the body. Even a very low dose will cause hormone disorder and metabolic toxicity.

5.Waste Water Ratio:The waste water ratio is the ratio of water production and waste water discharge of RO water purifier. The higher the waste water ratio, the more water is saved. Generally, the waste water ratio is 1:1 and 2:1. If the waste water ratio is too high, it will increase the pressure on the membrane, then the service life of the membrane will be shortened and the corresponding cost will increase.

6.Faucet:Some water purifiers are equipped with intelligent faucets, which have the function of reminding the filter element replacement, so as to avoid wasting money by replacing it too early and affecting the filtering effect by replacing it too late. In addition, the intelligent faucet can display the TDS value of incoming and outgoing water in real time, and clearly understand the filtering situation of each glass of water. At the same time, we should also pay attention to the lead-free faucet!

The quality of water affects our health. When choosing a water purifier, we should comprehensively consider the above points and choose a water purifier suitable for our family to protect the drinking water safety of you and your family!
