Nowadays, the sales of water purifiers continue to increase, and many families have joined the trend of installing water purifiers. The change in drinking water methods has improved the quality of life. However, there are also some people who buy water purifiers and leave them unused. Part of the reason is The replacement of the filter element is too expensive and not cost-effective. Some people think that the replacement of water purifier filter is the business routine, not worth installing, is this really the case? Let's learn some facts, don't be fooled!

Is the replacement of the filter element of the water purifier a routine for merchants?

If the water purifier does not change the filter element, it may attract more people to use it. The replacement cost of the water purifier in the later period is not low. Different brands range from several hundred yuan to thousands of yuan. Some families are unwilling to bear it and do not understand the replacement of the filter element of the water purifier. It is easy to buy the water purifier and not use it. so water purifier replacement is not routine?

This is really not a routine. Why must the filter element be replaced? Let's first understand the filter element of the water purifier.

In order to ensure the water purification effect, the water purifier selects the appropriate material for the more common substances in the water. The main filter element is PP cotton, activated carbon, ultrafiltration membrane and RO membrane filter element!

PP cotton filter is mainly responsible for intercepting large particles of sediment, colloids and other solid substances. As the first filter element, it filters large particles of pollution first, and the small substances are responsible for the latter filter element! PP cotton material is mainly polyester fiber, similar to the material of medical masks, one-time use, due to replace. Do not replace the filter, no filtering effect, but also secondary pollution of tap water!

Activated carbon filter, it is mainly responsible for the adsorption of odor gas. More common in tap water is residual chlorine, activated carbon in order to ensure good adsorption effect, choose good adsorption effect of materials, such as charcoal, bamboo charcoal, a variety of fruit shell as raw materials, which coconut shell adsorption effect is best, can be a good adsorption of odor in water, but also has the role of decolorization. However, after the adsorption of these materials is saturated, there is no effect, and a new filter element needs to be replaced to ensure the filtering effect!

ultrafiltration membrane

The ultrafiltration membrane filter element mainly intercepts tiny substances. For substances that cannot be intercepted by the first two filter elements, its filtering accuracy is better, so it is placed in the back to further filter, mainly for tiny substances of 0.01 microns. Ultrafiltration membrane is made of high-quality hollow fiber membrane material packaging, good hydrophilicity, strong anti-pollution ability, not easy to fouling. The use cycle is generally one to two years, and there will be a lot of dirty substances on it. Even if it is cleaned, it cannot be cleaned. A new filter element must be replaced!

RO membrane filter element has the best water purification accuracy, further purifying the invisible tiny substances in the water, such as bacteria, viruses, heavy metals, etc. The filtration accuracy is 0.0001 microns. The pressure pump is increased to allow water to penetrate the membrane to achieve the effect of water purification. The filtered tap water can achieve the effect of direct drinking! This RO membrane filter element basically loses its function after using it for 2 to 3 years through infiltration. The RO membrane gradually loses its effect after continuous work, so it is not a simple cleaning solution.

The filter element of these water purifiers, because of the material and the use cycle, must be replaced with a new filter element to maintain the water purification effect and reduce the dirty substances on the filter element that will pollute the tap water! Therefore, the filter element of the water purifier must be replaced, not a trap for businesses. Different brands of filter replacement costs are different, so before buying, you must understand clearly, choose a general-purpose filter element, do not limit the brand, choose diversification, and choose a relatively low-cost filter element.

Is the water purifier worth installing? Don't be fooled, uncover the facts

Some people think that buy water purifier, it is better to buy mineral water to drink, bottled water is just as cheap, in fact, we have to look at a more comprehensive situation!

First, the water purifier is suitable for families and areas with large drinking water. Mineral water is only suitable for mobile use, it is not convenient to carry cups, bottled mineral water is only suitable for drinking water, when you need to drink boiled water, wash vegetables, etc., bottled mineral water is not suitable. Water purifier installed in the kitchen can solve the family washing and cooking water, but also to meet the needs of family drinking water. In addition, the water purifier is installed in the public domain, which is convenient for drinking water and improves the convenience of drinking water!

Second, the long-term use of water purifiers does not necessarily cost a lot. Barreled water looks very cheap, in fact, it is only suitable for drinking water needs, and when there are many people, the water consumption is large, and the cumulative cost will not be low. Water purifiers use a wide range of water, more people use water, long-term calculation of the cost will not be higher than bottled water.

Third, the water quality in some areas is relatively poor, and only water purifiers can help filter and improve water quality. We can see that the quality of tap water is relatively good, which is most of the cases, but we cannot generalize. In some areas, the water quality of tap water is relatively poor and the hardness is high due to the current environmental impact. In some areas, because of all kinds of drinking water, it is not municipal tap water. Household drinking water can be solved in other ways, but tap water is still needed for kitchen cooking, washing vegetables, even washing clothes, etc. Water purifier can solve the problem of water in a large area, convenient and quick!

In short, the water purifier is worth installing if it plays a role where it is needed. In some areas, the water is clean and there is no need to install it. The key is to choose the right product and not be misled by some wrong remarks. Water purifier to choose the type of regular replacement, it must be strictly replaced, which is determined by the nature of the product.
