OFweek smart home network news due to their own occupation often contact with the water source, when the discovery of the country's self-drained wells can not be used, and the reconstruction of the water plant, we know that our ground water pollution is also very serious, so before moving into this new home, home Has been boiled water + Bi-Rand filter kettle to ensure the safety of drinking water, but after a person moved into a new home, plus work is busy, so I am still very keen to buy products that can improve the quality of life (in fact, lazy is also an important factor), one step in place Purchased a water purifier with instant heating. Before the purchase, the earliest consideration was kitchen-style, but since the garbage disposal was installed, the space under the sink was found to be smaller, and the toilet was abandoned. In addition, the hot-water purifier connected to the faucet was also seen on the Internet. It is not very convenient for each use to switch between tap water and purified water. In addition, some high-end water purifiers, such as the Pentair Central Water Purification Kit, can be said to be cheaper than Yunmi's. Finally, it is considered comprehensively.
"Water purifier type"
At present, there are mainly two types of household water purifiers in the market, namely, reverse osmosis (RO) water purifiers and ultrafiltration membrane water purifiers.
The most important component of a reverse osmosis water purifier is a reverse osmosis membrane. In simple terms, you can think of it as a very dense and dense sieve. The sieve pores are fine so that only water molecules can pass through, and other molecules cannot pass through. In addition, reverse osmosis water purifiers need to continuously discharge wastewater during the production of water, which is to wash out unacceptable impurities so as not to accumulate on the surface of the reverse osmosis membrane. Of course, the aforementioned "waste water" is not useless, and the user can buy one himself. A small bucket, placed under the sink, is connected to the “waste water†of the purifier, which is then used to water the flowers, flush the toilet, and so on.
The most sophisticated filter for ultrafiltration water purifiers is an ultrafiltration membrane, which has a much lower pore size than reverse osmosis membranes, typically 0.5-0.01 microns. Combined with PP and activated carbon filters, it can remove common sediment, mud rust, bacteria, and disinfectant residues in tap water. But like ionic substances in water, such as minerals, heavy metals, and organic matter, it is powerless. In simple terms, the result of using ultra-clean water purifiers is that drinking water contains minerals, but the water may also contain heavy metals.
In addition, there are different opinions on the Internet. For example, some people say that drinking water from reverse osmosis water purifiers for a long time will lack minerals and trace elements, but there are also saying that these trace elements can be supplemented by food, but I have turned a long time. None of them found an authoritative answer: "Can these microelements in the water be supplemented by food?" In this case, it might be better to buy Evian water, but the price is even more impressive.
"Unpacking"
As I said so much, looking directly at the product, the packaging is actually quite large, and some of its features are printed on the side.
In fact, after removing the packaging, the integration of the product is still good. In addition to the machine itself, there are four elements that need to be used, as well as three-way ball valves and a 32mm wide sink.
The three-way ball valve is mainly used to change the water inlet pipe in the home, so that the use of the water purifier does not affect normal kitchen water consumption.
The design of the machine is quite simple. The front is the LCD panel of the product. The following is the outlet of the product.
Close-up of the operation panel, mainly through the touch to complete the operation.
Just above the dust cover of the product, it is also where the filter element is installed.
When you open it, you can see the groove where the filter element is installed. The installation instructions are printed on the panel to facilitate the user's operation.
The installation method is very simple. Insert the filter element into the machine according to the serial number, and then tighten it clockwise to complete the installation.
The back of the product is the power cord, water inlet pipe and waste pipe. The following nameplate has printed some technical parameters of the cloud rice water purifier, including the flow of purified water, the applicable water pressure and temperature, and so on.
Two pipes, the water inlet pipe and the aforementioned three-way ball valve can supply water to the machine.
Let's say that there are four filter elements in the machine with the corresponding names and functions.
The first layer is PP cotton filter, which is generally used for the first purification of the water purifier, and is mainly used for filtering large particles such as mud rust and iron sand.
Both the second and fourth layers are granular activated carbons, front and rear, with slightly different functions. The main adsorption of residual chlorine, odor in the front; rear for improving the taste.
The third layer is an important part of this equipment. The RO reverse osmosis membrane filter has a flux of 400G (gallon), which is much larger than that of the same series X3 100G (gallon), and the outlet water speed is faster than similar products. Of course, the role of the RO reverse osmosis membrane is mainly to remove water scale, heavy metals, viruses, antibiotics, etc., filtered to get pure water.
"installation"
This machine is equipped with installation services, but I am not a first-tier city, the installation requires an appointment, so I see the installation is not complicated to do it yourself.
The installation is simple. First remove the original faucet from the tap water inlet and install the three-ball valve.
Of course, please remember to close the valve when you install it, or you can prepare it when you drop it. Haha.
The installation of the water inlet pipe needs attention. The size is tight. I used boiling water for a period of time. After the pipe is softened, the buckle can be placed on the three ball valve.
My pipe is directly from the sink basin. When installing, remember to put the 32mm pipe on the card to prevent the water purifier pipe from being cut by stainless steel.
"use"
The installed appearance does not require electric kettles and water bottles any more.
The water purifier has a small footprint and is basically as large as one A4 sheet.
The first time you install it, the machine will automatically clean it once. It takes about 10 minutes. Because these filter elements like activated carbon, in the transport configuration, shaking ah friction will produce a powder, so cleaning the filter to fully purify. However, Tucao is that the cleaning process is very troublesome. The machine is very heavy and needs to move the outlet of the machine to the wash basin. If the water outlet can take over the small water pipe, then it is just fine.
After cleaning, it can be used normally. There is a lock on the panel. Each time you use it, you need to touch and unlock to prevent misoperation. If no one operates 5s, it will automatically lock again.
The operation is still very simple, from the top to the bottom three steps, set the water temperature first, then select the capacity, and finally press the water key. On the panel, three common water temperatures are set by default, which are normal temperature cold water, 90° warm water, and 99° boiling water. When I brewing tea, I usually use boiling water; like drinking plain water, I usually choose warm water and drink it directly; but if I drink milk before going to bed at night, I need to use the plus/minus sign on the panel to adjust it.
In terms of capacity, different cup sizes are also set by default, which are 120ml, 320ml and 560ml, respectively. Like the usual hand to choose the first capacity on the line, go out in the morning in winter, choose 320ml, 90 ° will be able to get hot water flask, and drink it is not hot.
In terms of water temperature, it can basically reach the “1s that heat†marketed by the merchants. After a test, even if it is turned to the highest boiling point of 99°, pressing the water key will hear the internal operating sound of the machine, and the hot water will immediately come out. After testing with a thermometer, the temperature was at 98.8°, which was basically consistent.
Basically, a 120ml cup needs to be filled for about 10s, and the speed is about 12ml/s. It will not allow the user to wait for a long time.
"Water Quality"
I compared the water treated with tap water and water purifiers.
Through the TDS pen test, the particles in the water are well purified. Of course, it should be noted that the TDS value is only a standard for detection and is suitable for most situations, but it should be noted that the lower the TDS, the more representative the impurities in the water. cut back. However, more than 100 TDS values ​​do not necessarily mean poor water quality. For example, if you buy a bottle of Evian water, its TDS value may exceed 100 because it contains a lot of trace elements such as minerals.
In terms of taste, I personally feel that the gap with mineral water is not great, because the fourth layer of cloud rice uses a rear-grain coconut shell activated carbon to improve the taste, and on the whole it can still taste a little sweet.
For example, I like to drink coffee at home, and directly using the water tank to connect the boiled water is more convenient than using the built-in dry coffee machine, because the coffee machine was connected to the tap water to burn it. Over time, there is obvious scale, and then The amount of water coming out of the coffee machine is getting smaller and smaller and it needs to be cleaned several times with white vinegar and detergent.
"App"
Although Yunmi is Xiaomi's eco-chain company, this water purifier currently only supports the “Yummi Mall†app and does not support “Mamiâ€. However, it is similar to the previous Mi’s operation method, such as rapid adjustment of water temperature and outlet flow. App also displays current TDS parameters and tap water temperature.
The App can also check the daily/weekly/monthly water consumption and filter status so that users can purchase and replace them regularly.
The design life of the four-stage filter cartridge is also posted in the App, and when it is found that the filter cartridge decreases rapidly, it can be purchased directly through software.
In addition, App also has an intimate function. When it is found that there is no water record at home for more than one day, it will automatically send text messages to users. This is good for users with elderly people at home, because the elderly do not use water purifiers at home will make people doubtful. .
"cost"
Based on the life of the filter above and the official price, I figured out the cost of use.
Grade 1 filter - 79 yuan
Grade 2 filter core - 89 yuan
Grade 3 filter -599 yuan
4 filter element -89 yuan
Therefore, the annual fee is basically 79*2+89*1+399*1+89*1=735 yuan, almost 2 yuan per day.
Together with buying a bucket to use the waste water, I personally think that the cost of one year is still lower.
When the machine is running, it also has a built-in UV disinfection, so that the water purification effect is better, 60000 hours, without replacement. This doesn't feel useful, because there are no specialized bacteria detection devices at home.
"to sum up"
As a water purifier of RMB 8999, I will talk about its advantages and disadvantages.
advantage:
Easy to use, small footprint, good purification effect;
Easy to install, easy to disassemble, and can also be used for moving.
That is, thermal function, rapid water discharge, large flow, suitable for lazy people.
Disadvantages: Price personally feels high
In general, the machine can still feel a lot of convenience in daily use, especially for young people who are lazy and boil water. It takes three steps to pour kettles into kettles and then pour them into kettles. Yunmi's solution, which can be said to be a one-step solution, does not need to consider other issues in addition to replacing the filter element in the later stages. Of course, for the issue of price, this is a matter of opinion. It also takes everyone’s affordability into consideration. I moved into a new home before I considered buying, because I basically bought everything in one step... I was too lazy to upgrade my mind late. If you think the cost is too high, you can also buy better electric kettles (such as zoji) and water filters to solve the water problem.
