In recent years, water pollution accidents in China have occurred with a high frequency. The increasingly serious water pollution poses a great threat to people's water health. More and more people are beginning to pay attention to water health. However, as China's water purification industry has just started, the overall industry is not standardized, and the good and the bad are mixed, so we should pay attention to avoid some common mistakes when purchasing water purifiers.
Mistake 1: Go to the mall to buy
Many people may first think of shopping at the mall, but compared with Yisheng Water, which has many kinds of products and integrates the sales, installation and post-service of water purifiers, the mall generally has the problem of single products and high prices.
1. Single product: customers like home plaza usually have completed their water and electricity at home, so the water purifiers in the shopping mall are installed for the houses that have been decorated and installed. Only the end water purifiers can meet the drinking water, accounting for only 10% of the domestic water. If there is a high requirement for water quality: the kitchen water and domestic water are required to be purified, the end water purification is far from being achieved.
2 Can't buy the right products: The shopping guides of various brands in the mall say their own words and slander each other, so that consumers don't know which statement is correct. In the fog, they can't get professional and objective recommendation and buy the right products.
3. High price: Because all the water purification brands in the mall rent the venue of the mall, in addition to paying the venue rent, they also have to pay the mall discount points, resulting in high price.
Mistake 2: Buy online
Many people may be used to online shopping, but household water purification products need long-term and stable post-service due to their particularity, so online shopping will also have many inconveniences:
1. Blindness: We can't see the real products, experience the specific effects, and don't know what kind of water purification products to buy. Blindness is big, and we don't even know when we buy wrong. You can personally experience the water purification effect of the water purifier by purchasing it in offline physical stores.
2. No water purification design and installation service: no professional personnel carry out the pipeline design, the water inlet/power supply reserved position, and the construction disclosure can only rely on the decoration water electrician, but the water and electricity workers do not understand the water purification, which will lead to the wrong connection of the water purification pipeline. Unprofessional installation and connection can easily lead to water leakage, damage to decoration, and no door for complaint.
3. No after-sales maintenance guarantee: no one tracks the after-sales replacement of the filter element. Dirty and smelly filter element will lead to worse water quality. In addition, once the product fails and cannot be sold, it can only be scrapped and bought.
Instead of buying a set of water purifiers without guarantee for hundreds of thousands of dollars cheaper, it is better to spend this money to buy a guarantee for a regular and powerful water purification company.
Mistake 3: Buy in small stores
As a new industry, the water purification industry has many water purification brands, and the market is chaotic. It is more secure to go to the main store to buy. There are a lot of groceries, fake goods and fake goods in small stores, and the quality is not guaranteed. If a store selling water purifiers still sells bottled water, can you trust to buy their water purifiers?
2. No after-sales maintenance guarantee: small stores have weak anti-risk ability. Once closed, there is no filter element replacement. Once the product fails, it cannot be repaired, and only the whole machine can be scrapped.
Mistake 4: The more expensive the water purifier is, the better the filter element is
To buy a water purifier, you should first look at the filter element. The quality and quality of the filter element determine the quality of the water quality, but it does not mean that the more expensive the water purifier is, or the more filter elements are, the better. Like putting four or five simple filter elements, the filtering effect is not as good as putting a high-performance filter element; The water purifiers with the same effect are generally more expensive than the domestic ones, but the domestic brands are more suitable for the domestic water purification environment because the original ones do not make any improvement and copy the foreign products.
At present, the common filter elements on the market include metal mesh, quartz sand, PPT cotton, ceramic filter element, microfiltration membrane, ultrafiltration membrane, nanofiltration membrane and RO reverse osmosis membrane, and the filtration accuracy is also from low to high.
So what's the difference between different filter elements?
The filtering accuracy is different.
Different filter elements=different filter apertures=different filtering accuracy. The higher the precision, the cleaner the filtered water is
RO reverse osmosis membrane, only H ₂ O is filtered out, so it is called "pure water". In addition, there are four generations of common filter elements in the market, namely, split filter element, intubated integrated filter element, snap integrated filter element and snap split filter element developed by Altrand Water Purifier combining the advantages of split filter element and integrated filter element.
First generation: split filter element
Features: the filter element is separated from the filter bottle, and the filter bottle is connected by screwing
Advantages: The filter element and the filter bottle are separated, which can be opened to observe the use status of the filter element to determine the reasonable replacement time
Replacing the filter element does not require replacing the shell, and the replacement cost is low
Disadvantages: plastic aging after a long time; The filter bottle cannot be unscrewed and the filter element cannot be replaced, resulting in the scrapping of the whole machine
Too many times of replacing the filter element can easily lead to thread slipping, misplacement and deformation of the sealing ring, and water leakage due to poor sealing
Inconvenient replacement of filter element
Second generation: intubated integrated filter element
Features: also known as Korean filter element, the filter element and filter bottle are integrated and connected with the machine through intubation
Advantages: the filter element and filter bottle are integrated, and it is not necessary to unscrew the filter bottle to replace the filter element, which is more convenient than the split filter element replacement
Adopt intubation connection to avoid thread slipping of split filter bottle
The sealing ring is misaligned, deformed, and leaky
Disadvantages: the filter element and the filter bottle are integrated, and the shell cannot be opened to judge the use status of the filter element
Unable to determine the replacement time; The waste is changed early, and the water quality is poor when it is changed late
When replacing the filter element, the filter element shell is discarded together, and the cost is high
Replacing the filter element requires professional skills, and it is easy to leak if the tube is not inserted in place
Third generation: snap integrated filter element
Features: The filter element is integrated with the shell, and is connected with the machine in a snap connection
Advantages of filter element: the filter element and filter bottle are integrated, and it is not necessary to unscrew the filter bottle to replace the filter element, which is more convenient than the split filter element
Snap-in connection, more convenient to replace filter element, safe and watertight
It avoids the sliding thread of the split filter bottle, the misplacement and deformation of the sealing ring, and the sealing is watertight; Avoid water leakage if the integrated filter element is not inserted in place
Disadvantages: The filter element and the filter bottle are integrated, and the shell cannot be opened to judge the use status of the filter element, the replacement time cannot be determined, the replacement time is wasted, and the water quality is poor after the replacement, when the filter element is replaced, the shell of the filter element is discarded together, and the cost is high
The fourth generation: plug-in split filter element: developed by Altrand water purifier combining the advantages of split filter element and integrated filter element.
The filter bottle is connected with the machine in a snap-type connection, which is convenient for replacing the filter element
The filter bottle is separated from the filter element, and the filter element is replaced without replacing the filter bottle
Advantages: Compared with split filter element:
Snap-in connection, easy to disassemble and replace the filter element
Avoid plastic aging and the complete machine scrapping caused by the filter bottle can not be unscrewed
Advantages over integrated filter element:
The separation of filter element and filter bottle can be opened to observe the use status of filter element for reasonable replacement
Replace the filter element without replacing the shell, low cost
Mistake 5: Foreign water purification brands are better than domestic ones
1 Foreign brands are not suitable for the domestic market:
2. In the case of backward municipal water supply facilities, lack of primary filtration, the end is too simple, and the filter element is easily damaged:
3. The volume of central water purification and soft water is too large and there is no installation position;
4 Domestic drinking water is used to drinking hot water, while foreign brands do not have heating products.
5. Domestic municipal water purification process, water pipe network and household water quality are relatively poor in Europe and America;
The Chinese people are rich in food, cold in constitution and accustomed to drinking hot water;
7 The domestic residential area is small and the installation location is limited.
6： Easy to ignore installation process and after-sales service
Everyone who has done water purification at home knows that water purification is actually a very complex system, and its pipeline construction and installation process are dozens of times more complex than hydropower construction; So in addition to selecting the right products, it is also very important to select a professional and reliable water purification company. Yisheng in Changsha is equipped with professional technical department, professional engineering department, professional quality inspection, one-to-one post-service, on-site experience area, etc., which can show the professionalism of their company. Moreover, due to the particularity of water purification products, the filter element needs to be replaced regularly to ensure the quality of water purification, so it is very important to provide after-sales service. Yisheng's 24-hour after-sales service is more difficult for some ordinary water purification sales companies to achieve. Finally, the teachers are all trained professionally and will be assessed regularly. I saw them in the assessment last time, so I don't need to worry about the wrong connection (such as mixing the water inlet and the waste water outlet). It may endanger health instead of achieving the water purification effect.
Finally, remind the owner that the water purification equipment should be installed when the new house is decorated, and the water pollution is becoming more and more serious. In the future, the whole house water purification system is the trend. The installation of the new house can be based on the overall consideration of the space position and the concealed burial of the pipeline, so as to avoid the trouble of knocking on the wall and reworking after the completion of water and electricity construction. Moreover, the whole house water purification system must be installed when the new house is decorated.
