For this phenomenon, merchants have seen business opportunities and have launched various water purification products. If there are too many brands, which brand should be purchased is suitable for you. If you don't know it in advance, it may lead to the purchase of the wrong water purifier, or be fooled by the business. Next, let's talk about the purchasing skills of the water purifier.

1. The water purification system has different water purification effects.

Be sure to understand the water purification effect of the water purifier before purchasing. (1) The primary filtration water purifier has a simple structure and is mainly activated carbon. Its filtration capacity is limited and can only be used for coarse filtration. The filtered water is preferably heated and boiled for drinking. Most of the primary filtration water purifiers are low-grade water purification products. (2) Multi-stage filtration water purifier: This water purifier has two-stage coarse filtration and one set of fine filtration, and the fine filtration adopts hollow fiber filter core, and the filtered water can be directly consumed. The multi-stage filtration water purifier is a mid-range water purification product that can be accepted by the working class and is currently used by the family. (3) Ultrafiltration nanofiltration membrane water purifier: It has multi-stage pre-filter and ultrafiltration membrane, which can effectively filter out organic pollutants such as antibiotics, hormones, pesticides, petroleum, detergents, algae toxins, lead, cobalt, Harmful heavy metal ions such as antimony, mercury, cadmium, and chromium, as well as most scales, while other mineral ions are easier to pass. Therefore, the nanofiltration water purifier is an ideal water purification product while removing pollutants and retaining minerals beneficial to the human body. Belongs to popular consumer goods.

2, according to water quality

The water hardness of different regions is different. The high hardness water quality in the north of China and the limestone area in the south have high calcium and magnesium ion content in the water, which is easy to scale. The advanced filtration water purifier with ion exchange resin filter should be purchased. In urban water with chlorine, heavy color and odor, and organic content, you can purchase household water purifiers with more activated carbon. Because activated carbon has a strong adsorption effect on residual chlorine and heterochromatic odor in water, and has obvious removal effect on organic matter. For tap water purification with turbid water quality in urban and rural areas, household water purifiers with dual functions of coarse filtration and fine filtration should be purchased. For serious pollution in water, it is required to thoroughly filter out any impurities in the water. If you do not need to drink it directly, you should purchase a reverse osmosis pure water machine. Different water quality choose different water dispensers to meet our needs.

3. Determine the water output of the water purifier according to the population.

There are many types of water purifiers, such as kitchen water purifiers, household water purifiers, kitchen and drink all-in-one machines, straight drink machines, water softeners, whole house water purifiers, etc., which meet different needs, but the main points of the current household There are two kinds, one is a direct drinking machine that directly drinks water, and the other is a domestic water machine, which is used for daily washing, cooking, soup, etc. We can give an example, taking a family of 7 as an example. We calculate the amount of water needed for each person in the summer of 1.6 liters, then 7 people are 11.2 liters, and the bottled water is generally 16 liters, so the day is almost a bucket, in the face of this amount of drinking water, It is necessary to understand the water flow of the water purifier before installing the water purifier and purchase it correctly.

4, choose a well-known water purifier brand or have a related license water purifier

In the water purifier market, the brand is full of flowers, in the end, which brand is good, consumers can look at the famous big brands first, such as Chen Xiaochun endorsement of Huamai water purifier, Huang Haibing endorsement Linster water purifier brand is the domestic water purifier Well-known brand. If it is an unfamiliar brand, you may wish to check the water purifier test report and qualification certificate to see if the brand has a health permit endorsed by the national department, whether it has passed the appraisal of the State Technical Supervision Department, in line with the national “Drinking Water”. Water quality standard. This is a necessary condition to ensure the purchase of a regular water purifier.

5. Understand the characteristics of the water purifier and the local water quality.

At present, there is no uniform purchase standard in the water purifier market. Many consumers do not have a specific concept when purchasing water purifier products. The appearance and several filter elements are combined with the price and price. So caught in two water purifier purchase misunderstanding: (1) the more water purifier filter, the better the filtration effect (2) the higher the product price, the more secure the quality. This has also led to many unscrupulous business opportunities to maliciously increase the number of filter elements and soaring the price to fool consumers. In fact, the price/performance ratio is mainly determined by the adaptability of the water purifier and the local water quality, combined with the water purifier filter material and technical content.

6, the improvement of product after-sales service is one of our selection criteria

Because of the characteristics of the products, the after-sales service is very important. The service installation, the later filter replacement, and the product failure maintenance are all big troubles that consumers cannot solve themselves. Therefore, consumers must purchase the household water purifier. To learn more about the brand's after-sales situation.

When choosing a water purifier, we don't need to follow the high price purchase or the more the filter water, the better. These are just some of the gimmicks of the business. If the actual water purification effect is good, you should choose according to your living environment and population. At the same time, we must pay attention to whether the after-sales service is perfect, and if there is any quality problem, it can be replaced or repaired immediately It is recommended to choose a larger brand of services and quality in all aspects.
