preface

Water is the source of life. With the development of industrialization, the economy has grown rapidly, but the environment has suffered serious damage. News of various water pollution often rings in my ears. In the face of increasing water pollution, we can only use scientific and technological means to drink a safer drinking water, of which the water purifier has become a household artifact, What Smart Fan brings to you today is a review of the MAX-RO water purifier from Cool Frog. I hope it can provide some reference when you choose to buy water purifiers.

Unpacking

From the perspective of the outer package, this water purifier is medium in size among its peers. It is a smaller size than the kitchen style of a certain meter that was drawn at the annual meeting of the company years ago. However, as a home product, this one is more suitable in size and occupies a slightly smaller area. The outermost package is a plastic package printed with the manufacturer's logo Cool Frog. Inside is the conventional environment-friendly two-layer honeycomb carton packaging, which is slightly thin.

On the left side is the product name, model, color and other relevant data, including packaging volume: 370 * 405 * 328mm, net weight: 6.5KG, which is considered light in water purification equipment.

The first thing I saw when I opened the package was not the water purification equipment, but the instructions, two boxes of accessories and hoses, and the foam that fixed the water purifier and protected it.

When the foam is uncovered, the protagonist appears on the white top surface. There are two function keys (flush and reset) and an OLED display screen at the lower right corner. The gold part is made of plastic, and the rest is made of metal. It is also wrapped with a layer of plastic protection. The protection of three layers inside and three layers outside shows the intention of the manufacturer for products and customers.

The front is a very simple PC shell, and the LOGO in the middle and upper position is the only ornament on the whole surface. Although the package mark of the product in this evaluation is gold, except for this panel, it is gold. Both the left and right sides and the top are white. I can't distinguish the colors of the manufacturers clearly.

The whole panel can be removed after a little disassembly. Is the quality too poor? No, the original four corners of the panel are adsorbed by magnets. After the panel is removed, the LED lights are red, blue, and green when powered on in the unconfigured state, but finally the green light is always on. Removing the panel also allows you to have a more intuitive understanding of the internal structure.

It is very simple to install the panel back. Just align the four corners directly and attract the magnets.

The anti slip mat at the bottom is designed to be more convenient to place at home. Although the appearance is ordinary, it is more practical.

On the back is the 4-tube filter element and the guide for replacing the filter element. The lower left corner is the power interface, and the lower right corner is the concentrated water outlet, water purification outlet, and water inlet. As for the method of replacing the filter element, the manufacturer's guidance only said that the filter element should be turned counterclockwise to the OFF gear, but it did not say that tools were needed.

Finally, the tool was found in the accessory box.

After the filter element is disassembled, the weight of the water purifier is reduced by half, and it is emptied instantly, leaving only a layer of iron sheet. Four times of filtration, followed by No. 1 PP cotton filter element, is mainly used to filter large particles of impurities, which are generally replaced every three to six months, depending on the local water quality. The No. 2 pre activated carbon filter element is mainly used to eliminate the residual chlorine used for disinfection in tap water, as well as other odors. It should be replaced once every six months. No. 3 is the largest tank. The RO membrane filter element has a filtration precision of 0.0001 μ m. It is mainly used to remove bacteria, viruses, organics, heavy metals, ions, etc. from the water. The desalting rate is more than 90%, which can completely remove ionic impurities (scale). The taste of bottled or barreled water can be achieved. It should be replaced once every 18 months. As for whether the official publicity effect can be achieved, It will be announced later. The No. 4 post activated carbon filter element can improve the taste and absorb odor, which is equivalent to that of No. 2 filter element. Since the water quality of this filter element has been treated completely, the replacement cycle of the filter element can be as long as 12 months.

Installation

Before installation, I read the official operating instructions carefully, and found that the paper instructions were not detailed enough. We can only do it under the guidance of the official installation video. The first step is to determine the type of your own faucet. There are basically three kinds of faucets with external teeth, ordinary faucets and internal teeth faucets. The faucets with external teeth are the ones for the small weavers to choose the right accessories and get started directly.

For the external thread faucet, the first step is to remove the bubbler at the outlet of the faucet and replace it with a large twist sleeve. Since the official accessories consider the user's various faucets, there are surplus accessories, so the second step is to select the internal thread accessories suitable for the external thread faucet and pad them with gaskets. When the manufacturer ships again, it takes all kinds of faucets into consideration, So after the installation, there are some spare parts left. The manufacturer's serious attitude is really satisfactory. The third step is to tighten the internal thread connector with gasket to the front end of the faucet. If users are worried about water seepage, they can wrap several circles of raw material tape (commonly known as adhesive tape) around the thread of the faucet. The last step is to directly connect and tighten the double tap.

Connect the water pipe to the corresponding water outlet, and the hardware installation is completed.

Distribution network

Connect the power, long press the reset key, and observe the indicator light. After the blue light flashes, WiFi graphics will appear on the display screen for distribution network. The difference between the Kuwa water purifier and other smart products is that there is no need to download the APP, and you can use WeChat directly. Scan the QR code on the right side.

The distribution process of Kuwa water purifier is very detailed and has a high success rate.

It is also very convenient in operation. After the distribution network, you can directly view the bound equipment after following the public account, and check the water quality and other information.

The degree of use of the filter element and the amount of water used can be updated online in real time. The filter element can only be used normally after being washed twice for the first time to prevent internal water accumulation and bacteria breeding. The main color on the interface is blue, giving the impression that the whole picture is pure and pollution-free. This color is quite consistent with the water purifier product.

The TDS value of water quality is 10 on the mobile phone and display screen, and 14 on the detection pen. To be honest, the water quality is infinitely close to pure water.

In the coastal city where Xiaobian is located, the TDS value of tap water itself is within 45, which belongs to good water quality. After the treatment of the purifier, the index decreases nearly three times, and the TDS is only 14. The value of 101 for concentrated water is average. In this process, it is found that the ratio of wastewater discharge and purified water output is almost 1:1. Every 5L of water used will automatically flush the equipment, which can be done in dozens of seconds. The cost of drinking a mouthful of clean water is to waste the same amount of water. Of course, compressed water can be reasonably arranged. Although it can not be directly drunk, it can be used to water flowers, as clean water, to maximize the use of water.

Finally, I made a small preparation of Shennong test medicine, and drank tap water and purified water directly. It didn't hurt. Tap water was drunk in the mouth, and the smell of disinfection was different. The taste of purified water was more delicate, almost the same as that of purified water, but the drainage ratio was 1:1. Experiments proved that this was not the case. The discharge speed of compressed wastewater was much faster than that of purified water, Therefore, Xiaobian is still skeptical about the proportion of wastewater.

summary

Advantages: From installation to use, the Cool Frog Water Purifier is really good, convenient and fast; Most of the 4-layer filter elements are made of imported materials. The monitoring data of mobile phone APP is clear, the purification effect data is clear, the taps are turned on, the switch is independent, and each use scenario is rationally considered. Kuwa manufacturers, thanks to their ten years of hard work in the industry, think more comprehensively, and attach importance to the user experience, which is vividly reflected from product packaging to practical use.

Disadvantages: The noise of the water purifier during operation is too loud. It would be perfect if the noise could be reduced a little more. In addition, this product is a kitchen water purifier. After the panel is removed, the internal structure is too simple. Do you consider the waterproof problem of the kitchen water purifier? Are there any other solutions for sealing?
