introduction

With the development of social economy and the improvement of material life, various pollution incidents are also emerging in endlessly. Although the country has always advocated reducing pollution from the source, the cruel reality is that we have no doubt embarked on the old path of pollution before treatment in developed countries. When we see those shocking pollution photos, we have to doubt everything, This is actually the biggest disharmony in the development of this harmonious society. Nowadays, water purifier is an indispensable household product for healthy and safe water use. However, in the face of a wide variety of household water purifier products in the market and various hype from businesses, the choice of water purifier really gives many families a headache.

At present, the most important domestic water purifiers on the market are RO and ultrafiltration products, and I have used both of these products for a long time. Even though three years have passed, I still can't forget that when I unpacked the RO water purifier, I felt a tremendous leap in my heart. There are so many accessories, including pipes, valves, and various bolts, I can't help sighing in my heart, where are all the industrial design talents in China? Give me such a semi-finished product. However, the assembly is not a magic horse. If you bother to install the master, the engineering man will be ridiculed. After hard research for a long time, it was finally settled. Later, the purchased ultrafiltration water purifier, The installation is much simpler, but the water purification effect of ultrafiltration is still not very reassuring, and each has obvious advantages and disadvantages.

This time, I was lucky to participate in the trial of the geek show Yunmi water purifier. Although I was surprised, I didn't have too many surprises when Xiaomi entered the water purifier industry. After all, Yunmi water purifier is also a smart home product under the ecological chain of Xiaomi. It also adheres to the concept of "making everyone enjoy the fun of technology", but these are beside the point, This article focuses on the practical experience of Yunmi water purifier and its comparison with traditional water purifiers, so that we can better understand the characteristics of this product, and also hope to give some references to friends who are ready to purchase household water purifiers.

The host adopts aseptic vacuum packaging, which is the highlight

After using two typical water purifier products, when I saw the cloud rice water purifier, I gave a big praise from the bottom of my heart. The whole package does not have as many accessories as the ordinary water purifier. From the vacuum packaging of the host, the control of the cleaner production process should be in place.

The identification of millet products on the packaging box is very high. The Mi label on the side and the coffee color label are all familiar and detailed millet features. The contents in the box are unexpectedly small. The host, filter element, accessory box and instructions are neatly placed in their respective slots, in good order.

The millet water purifier adopts a sterile and clean production environment, and the whole machine is vacuum packed. This has many advantages. It can not only better store special pipelines, but also ensure the cleanness and safety of the product transportation process, and ensure that users use brand new products. The accessory box is designed to pull, and each accessory is placed in a fixed slot. Such a large accessory box feels a bit wasteful, There is still room for compression in packaging design.

There is not much in the accessory box. Six adapters and a special screwdriver can perfectly handle most kitchen faucets. The four filter elements are PPcotton filter element, pre activated carbon filter element, RO reverse osmosis filter element and post activated carbon filter element. They are packed in blister, which is basically a typical configuration standard for RO water purifiers.

The instruction manual is very detailed. After reading it, I found that the installation and use of this RO water purifier is very simple. However, friends who use the water purifier for the first time should read it carefully to avoid making mistakes in the steps. For products with high integration, it is best to successfully equip them at one time.

High integration brings the advantage of simplifying RO water purifier

The integration degree of Yunmi water purifier is very high. All pipe fittings and valves have been preset in the host, without too much complicated connection and installation. The whole product is a real finished product, which does not need to assemble accessories. It only takes a few steps, and anyone can easily complete the installation without pressure. It is almost rare that water purifiers on the market can do this, The charm of innovative design makes me think highly of this water purifier.

When the vacuum package of the host is removed, it can be seen that the pipeline attached to the side of the host is actually fixed with the host. This design is more conducive to water leakage prevention and electric shock prevention of the product, making the use of the product safer. However, if maintenance is needed, it will be more troublesome.

The pipeline is fixed with a storage self-adhesive tape, and the valve is also covered with a protective bag. The manufacturer is very attentive to small details. Take out the valve, arrange the pipeline, and through the touch button on the valve, the water inlet interface, and the double water outlet at the bottom, you can know that its internal water path is controlled by the solenoid valve, which can not only directly open the tap water, but also connect the tap water to the water purifier, Then the purified water is discharged. The internal structure of the valve is relatively complex, and there are at least one in and one out of two water pipes and control lines in the connecting pipe of the valve. It can also be seen that this water purifier is really not simple.

However, the integration is so high that if there is a problem, the maintenance cost will be high, so the material and workmanship of the product is very important. From the details of the cloud rice water purifier, I feel that the overall workmanship is very good, and the simple and reliable installation and connection brought by the high integration is incomparable with ordinary water purifier products.

The parameters and production information of this water purifier can be seen from the production nameplate. This water purifier can be used normally under the pressure of 0.1~0.4MPa of municipal tap water, and can basically meet the use of low water pressure for users in high-rise buildings. Without a water storage bucket, it can maintain a pure water flow of 1L/min, which is very expected.

The water purifier is a square cylinder with a round corner design, which is simple and beautiful. A 3-color LED status light is set at the top of the front, and the Mi logo and 400G logo are printed on the bottom. The overall color is gray, with fine lines on the top. The touch is good. The four corners of the bottom are designed with anti slip pads, and the sides are also equipped with carrying slots. The overall feeling is pretty good. After all, it is directly placed on the table, The face value must be high.

Open the cover plate on the top, you can see the inside of the water purifier. It is very simple. There is no pipeline circuit like the ordinary water purifier. Here, you can only see the four filter element hole positions, the filter element installation instructions, as well as the indicator lights and keys. The cover plate is directly designed with a movable buckle plate, which is convenient for replacing the filter element and resetting operations, Precautions and Wifi connection guidelines are also printed on the inside of the cover.

Before installing the filter element, briefly introduce the functions of the next four filter elements and the process of water purification. It can be clearly seen from the above figure that tap water enters the water purifier first through the PP cotton filter element to remove large particles such as sediment and rust, then enters the front activated carbon filter element to remove odor, residual chlorine and other substances, and then enters the core treatment section of the water purifier, RO reverse osmosis filter element is used to remove antibiotics, organics, heavy metals, nitrites, bacteria, etc. Since the RO process uses differential pressure to screen the incoming water, the bottom of the filter element is different from other filter elements in that there are two pipe holes, one in and one out. In this section, tap water is divided into purified pure water and residual concentrated water, The pure water can be directly drunk after it finally enters the post activated carbon filter element to improve the taste, while the concentrated water can be discharged through the concentrated water pipe and collected for toilet flushing, mop washing, flower watering, etc.

The installation steps are also very simple. Just insert four filter elements into the corresponding holes in turn according to the requirements, insert, press, rotate 90, lock, and the water purifier is assembled. There is no connection of various pipes and valves. Everything is so simple. This is also the embodiment of the high integration of Yunmi water purifier. In fact, these components were previously assembled by users or installers, All of them have been aseptic installed in the production workshop of Yunmi. What we need to do is to align the pipe holes of the inlet and outlet pipes at the bottom of the filter element with the interfaces in the machine, and complete the connection and sealing through the rotary switch. It is not easy to achieve this precision and internal design.

The connection of the valve is also simple. Take off the bubbler on the kitchen tap. Although the faucets of each house may have some differences, the Yunmi water purifier comes with six types of connectors. There is no problem with most household faucets. After screwing on the corresponding connector, insert the faucet interface end of the water purifier into the connector, and the installation of the water purifier is complete, The whole process does not need to remove any screws, which is simply not like the strength faction.

Deep access to smart home technology, enjoy the fun of technology at any time

During the experience of Yunmi water purifier, the overall impression of this smart home product is quite good. At least compared with the traditional water purifier, this water purifier has obvious advantages in installation and use. Of course, this water purifier is not perfect. There are still some shortcomings, mainly in noise and vibration, But it is also within the acceptable range, and has little impact on the use experience of the product.

Use the water purifier for the first time. After power on, open the water purifier valve and flush the protective liquid in the filter element of the machine. After about 5 minutes, the liquid flowing out of the concentrated solution pipeline changes from gray white to transparent, and the water purifier can be used normally.

As an intelligent product, especially an intelligent product under the Xiaomi ecological chain, the integration of the cloud rice water purifier and the Xiaomi smart home is in place. It uses Wifi connection, which is simple to operate and has good stability. However, connecting the water purifier through the mobile Xiaomi smart home app can keep abreast of the work of the water purifier.

For the first time, there will be a description of the tap indicator, and you can also view the complete electronic help document. After each time you enter the APP, the TDS value of the current tap water will be displayed, and then gradually change to the TDS value of purified pure water. By pulling up, you can view the use of the filter element, as well as the column chart of water volume and detailed statistical data. The entire interface is simple and clear, The process of purifying tap water into pure water is fully quantified, which is the advantage of intelligent products. If multiple digital screens on the host can display the TDS of incoming and outgoing water, it may be more intuitive.

Click the TDS value on the main interface of APP to enter the water quality curve chart, and check the water quality curve chart of inlet and outlet water at any time. From the water quality comparison, it can be seen that after the tap water is purified by the water purifier, The TDS value has been greatly reduced. It can be seen that the RO reverse osmosis process is still very effective in removing impurities in the water body. The purity of the purified water is very high, and the taste of the purified water after treatment has been significantly improved by the post activated carbon process. This is really not blowing. The RO water purifier used by my family before also has a post activated carbon filter element, and the taste of the purified water is really different, In the filter element status, you can also see the introduction of the filter element and the percentage of the remaining life of the filter element. It is felt that there can be an increase in the record of the time of putting into use, as well as the record of the previous replacement of the filter element. Of course, as a smart home product, it is also necessary to share usage and event push messages. Since Xiaomi began to layout the smart home product line from the smart router, It can be said that the experience in this area is quite rich.

In the actual experience, we found that the noise and vibration of the Yunmi water purifier in use are still relatively large, because this equipment is placed directly on the table, rather than the traditional water purifier, which is designed under the kitchen. The sound of the large flow booster pump is obvious when making pure water, but this water purifier uses the large flux membrane RO filter element, which can produce 400 gallons of pure water a day, The power of the water purifier has also reached 96W, which is relatively large in the water purifier of the same level. In order to use purified water more freely, this small noise and vibration is acceptable, but it is still hoped that the manufacturer can make further noise reduction and vibration reduction improvements.

In addition, this water purifier has a high degree of integration, including the integrated design of the holes and grooves of the four filter elements. Although this has certain advantages in water leakage prevention, dust prevention and installation convenience, it is basically impossible to clean and maintain the RO filter element section if necessary. However, the use time of the RO filter element section is relatively long, and the possible pollution of the chamber caused by replacing the filter element is very small, However, when replacing the filter element of post activated carbon, try to keep it clean.

As for the filter element, there is still an economic account to be calculated. The replacement cycle and price of the four filter elements are different. According to the replacement cycle and price of the filter element, the average annual shared cost will vary a little depending on the quality of tap water in different regions. The minimum price is about 506 yuan, and the maximum price is about 845 yuan. It can be seen that although the price of the cloud rice water purifier is 1299 yuan, it is not high, However, the cost of filter element consumption is not low. We hope that Yunmi can make full use of filter element to a greater extent in technology, control the cost of filter element in production, and give consumers greater benefits.

Compared with traditional RO water purifier, it has obvious advantages, but has its own advantages compared with ultrafiltration process

The following two water purifiers are traditional RO water purifier and ultrafiltration water purifier, both of which are water purifiers I am currently using, including RO water purifier, with a total of 5 filter elements. In addition to PP filter element and granular activated carbon filter element in the front section of RO, there is one more compressed activated carbon filter element than Yunmi water purifier, so this water purifier is designed with two water outlets, one pure water outlet and one clean water outlet, The pure water treated by RO reverse osmosis and post activated carbon is stored in the water storage tank, which is very good in purity and taste, but the continuous effluent capacity is poor, and the effluent from the water purification outlet retains most minerals, but the actual ability to purify pollutants is much worse than that of the ultrafiltration process. This machine has been used for three years, and the process of replacing the filter element is quite troublesome, In addition, there was a problem that the pressure of the primary water storage tank was reduced and the water could not be discharged. The risk of secondary pollution during maintenance is high. The ultrafiltration water purifier has the advantages of large water output, mineral retention, simple installation and maintenance, very little concentrated water, no power consumption, etc., but it has little effect on removing heavy metals, organics, and bacteria, rust, colloid Suspended solids and other substances are easy to block the filter membrane, reducing its service life. In areas with heavy water pollution, this kind of water purifier is not recommended.

(Traditional RO water purifier)

(Ultrafiltration water purifier)

Although Yunmi water purifier adopts RO process, it is relatively convenient in installation and maintenance, and its water purification effect is also very good. Through comparison and analysis with traditional RO water purifier and ultrafiltration water purifier, Yunmi water purifier has obvious advantages over traditional RO water purifier, but in comparison with ultrafiltration water purifier, it can only be said that each has its own advantages, no one is strong or weak, It can be selected according to the local tap water conditions and the needs of families. Finally, the advantages and disadvantages of cloud rice water purifier are summarized as follows:

advantage:

1. High integration, simple installation and maintenance, safe use. The third generation integrated filter element design is adopted, the pipeline is comprehensively arranged, and the installation is simple and convenient. There is not as much pipeline, valve and shell assembly as the traditional RO water purifier, and there is no need to change the pipeline of the kitchen faucet that has been arranged like the ultrafiltration water purifier. It is plug and play, extremely simple, and has good water leakage and electric shock prevention effects;

2. Large flux RO filter design, stable and sufficient water production. Compared with the traditional RO water purifier, which uses water storage buckets to increase the sustainability of water use, the Yunmi water purifier uses a high flux RO filter element to continuously supply 1L of water per minute, which is sufficient to meet the use needs of ordinary families, while reducing the link of water storage buckets and the rate of secondary pollution;

3. Good water purification effect and strong anti risk ability. Compared with the water purifier of ultrafiltration process, The filtration precision of RO process water purifier can reach 0.0001 μ m, which can remove heavy metals, organics and other harmful substances, can meet the direct drinking standard, and has stronger resistance to tap water pollution events. Compared with the traditional RO water purifier, the integrated design of cloud rice water purifier will minimize the possibility of secondary pollution during installation and maintenance;

4. Smart home design has strong expansibility. The high-precision TDS water quality probe and highly sensitive flow probe enable users to master the parents' water quality and water use situation through the APP terminal at any time and anywhere, and the water purifier conducts intelligent evaluation through regional water quality big data, home water quality detection data, daily use flow, replacement time, etc. to accurately estimate the life of the filter element. It is very convenient to see the remaining life of the filter element on the mobile phone at any time, With the development of APP, the possibility of interaction with smart cups and kettles at home will not be excluded in the future.

Disadvantages:

1. The noise and vibration are too large. This is a completely defeated ultrafiltration water purifier that does not produce noise and vibration. Even compared with the RO water purifier that my family has used for three years, the noise is still a bit loud. The main reason is that the Yunmi water purifier uses a large flux design and a larger booster pump;

2. High level of integration. If there is a problem, the maintenance cost is high. In particular, the filter element installation hole slot adopts an integrated body. In terms of cleaning and maintenance, it will be troublesome if there is pollution. Therefore, when replacing the filter element, be sure to pay attention to maintaining a clean environment;

3. Energy consumption is relatively high. The function of the complete machine 96W is higher than that of the general RO water purifier, and it is even more inferior to the ultrafiltration water purifier that does not use electricity. The annual cost of filter element consumables is 500 to 800 yuan, which has no advantage over the ultrafiltration water purifier;

4. No minerals, slightly acidic. Although many manufacturers now claim that there is no problem in drinking purified water for a long time, no problem does not mean that it is the most healthy. The most suitable drinking water for human body has a pH of about 7.4, rich mineral content, moderate hardness, moderate oxygen content, and no toxic and harmful substances to human body, which is the most valuable unpolluted drinking water source in natural waters, So my suggestion is that if the tap water quality is good, you don't need to drink too much pure water.

epilogue

Yunmi provides us with such good water purifier products, but drinking water safety is a heavy topic. In the face of a large number of water pollution events, we can do nothing. Although it is not unbearable for most people, many processes change from quantitative to qualitative. When pollution accumulates to a certain extent, it will cause irreversible losses, But now even drinking water is no longer safe, which makes people uneasy. To the extent that they want to drink pure water, which should only exist in the laboratory, it seems that there is no harm in this way. But in order to enable future generations to drink natural and healthy drinking water, they also hope that the country will strengthen governance and let nature, a natural purifier, return to the right track, In this process, it is still necessary for us to choose a suitable water purifier. Use it first!
