Why does my neighbor always come to my house to drink water? I found out the reason after using Suning XiaoBiu R400-W1 water purifier

With the rise of drinking water health issues, the demand for household water purifiers has gradually become hot. Behind this, users also have different needs. Therefore, before purchasing a water purifier, the most important thing users need to understand is their own needs for water.

If you are just looking for preliminary filtration, then the ultrafiltration machines on the market are sufficient to meet your needs; if you are only looking to remove scale, then a water softener will be a good choice; if none of the above can meet your needs, then a reverse osmosis (RO membrane) water purifier will be more suitable.

Different from the first two types, reverse osmosis (RO membrane) water purifiers can bring a purer direct drinking experience, which is both clean and convenient. What I got today is a reverse osmosis (RO membrane) water purifier, model Suning XiaoBiu R400 W1. Now let's experience this beautiful water purifier together.

Appearance

In terms of appearance design, the Biu R400-W1 adopts the consistent simple style of the series, with curved lines. The front is oval, not the square shape seen before. The design concept is extremely elegant and simple. From this point of view alone, not many users will reject its appearance. From the first glance, this water purifier feels like a "chassis", and its placement and movement are indeed as simple as a chassis.

Its overall dimensions are 500×330×455mm, and its slim body can be better accommodated in the kitchen environment, which is very friendly to users who are in a hurry for daily use. The overall load is mainly two filter elements. If you need to move it, Suning XiaoBiu R400 W1 is still very light.

The front of the Biu R400-W1 is the filter replacement port. The upper part is the PPC composite filter element, and the lower part is the RO filter element. When replacing, you only need to insert the filter element and rotate it to a horizontal position. There is a reminder printed on the surface of the filter element that this side is facing up, which is very considerate. One thing to note here is that when you actually install it, in addition to aligning the holes, you also need to push the filter element inward a little, otherwise the external handle of the filter element cannot be twisted to a horizontal state.

Its installation convenience is almost universal, so there is no need for a technician to come to your home to install or replace it. The official slogan of replacing the core in 3 seconds is used to describe this. From the actual experience, this is not an exaggeration at all.

Below the filter slot is the control panel of the Biu R400-W1. On the left are the indicators of the PPC active cotton filter and RO membrane. The blue light is always on for normal status. If it flashes purple, it means the filter has reached the life warning stage, and the red light flashes, which means the filter has reached the end of its life and needs to be replaced urgently.

The WiFi logo is on the right. Unlike the previous generation, the R400-W1 integrates the flushing and water-making button into the WiFi indicator light, so you only need to touch it to start the operation. The purple light that is always on indicates the water-making mode, and the flashing purple light indicates the flushing mode. We can understand the working status of the water purifier just by looking at the different lights, which is very convenient.

On the back of the machine is the product information and the DC power interface. The lower part is the water inlet, pure water inlet and concentrated water inlet (wastewater). Since the reverse osmosis RO membrane needs to be rinsed after filtration, a certain amount of concentrated wastewater will be produced each time water is produced. This leads to the concept of wastewater ratio, which is the ratio of produced water to discharged water. The wastewater ratio of the small Biu R400-W1 in our hand is 1:1, which is the common water-saving type on the market.

In terms of accessories, the Biu R400-W1 comes with the necessary PE pipes, faucets, and gasket light accessories. When installing, you can directly use the door-to-door installation service of the Suning platform, and the installation process is very simple.

Water purification capacity

This time, the Biu R400-W1 uses composite filter technology, so a few filter elements can achieve the effect of multiple filter elements. Not only is the product volume more advantageous, but it can also simplify the tediousness of replacing filter elements through higher integration. With these two filter elements, the Biu R400-W1 has a PP cotton filter element and a front carbon rod filter element. The former can remove other suspended impurities, and the latter can filter common substances such as residual chlorine. The taste filter material inside the carbon rod will also improve the taste of filtered water when water passes through it.

However, the most important thing about this water purifier is its RO filter element. Compared with microfiltration, ultrafiltration and nanofiltration, reverse osmosis RO filtration can achieve a more refined filtration effect, effectively filtering impurities such as calcium and magnesium ions and heavy metals, so as to achieve the effect of direct drinking. Reverse osmosis RO membrane filtration is also the most mainstream water filtration method at present. If your water filtration needs are for drinking rather than washing, then reverse osmosis RO membrane filtration will be the most suitable method.

In terms of filter replacement, the official claim is that the RO filter can be used every 2 years, while the PPC composite filter can be used every 1 year. The data here still needs to be judged according to local differences. If you are in the northern region, your replacement cycle should be shorter than the declared time in terms of water quality.

In terms of replacement cost, the current price of Suding PPC filter element is 119 yuan, and the price of RO filter element is 479 yuan. The flux of RO filter element is 500g. The price of 400g PPC filter element is 99 yuan, and the price of RO filter element is 379 yuan.

We use a TDS test pen to test here. TDS (Total dissolved solids) is the total amount of dissolved solids, which means "how many milligrams of dissolved solids are dissolved in one liter of water". Generally, conductivity is used for simple valuation. Please note that the TDS value is not completely linked to the quality of water. It can only measure how many impurities are in the water, but cannot judge the quality of these impurities. Therefore, it is not appropriate to use the TDS measurement value as a standard of quality. However, for reverse osmosis RO membrane water purifiers that focus on ultra-fine filtration effects, the TDS measured value can well reflect the effectiveness of this machine.

We first take a cup of tap water, and the test shows 425ppm. Although the domestic water standard stipulates that it should not exceed 1000ppm, but as far as the value of more than 400 is concerned, it still contains a lot of impurities, which can easily cause what we often call scale.

Next, we used Suning XiaoBiu R400-W1 for filtration, and the TDS measurement was 24ppm, which is enough to meet our direct drinking needs. Compared with the previous value of around 400ppm, it can be seen that the filtration capacity of XiaoBiu R400-W1 is still very strong.

Then we filtered the tea, milk and soy sauce mixed with water. You can see that the water filtered out on the left is very clear and pure, while the water on the right is the concentrated water mixed with three times, which is very turbid. Unlike ultrafiltration and other filtration methods, the accuracy of reverse osmosis RO membrane filtration reaches 0.0001 microns, while the accuracy of ultrafiltration is 0.01 to 0.1 microns. The former can obviously filter out more impurities, so the water quality will be clearer.

Intelligent

In addition to the conventional water purification capabilities, Suning XiaoBiu R400-W1 also supports Suning smart APP linkage operation. After connecting via WiFi (2.4G), users can see the standby, flushing and water production status of the water purifier on the main interface.

Not only that, you can also see the total amount of purified water, filter usage rate and water usage log, so as to deepen your understanding of the working condition of the water purifier. If you forget how to operate the water purifier, you can even open the accompanying electronic instruction manual in the upper right corner of the APP, which is really considerate for lazy people like me.

Through the above comprehensive use experience, we can find that the workmanship and efficacy of Suning XiaoBiu R400-W1 are sufficient to meet our needs. More importantly, this water purifier also has a distinct price advantage. The current market price of a 400-gallon reverse osmosis RO membrane water purifier is more than 2,000 yuan, while Suning XiaoBiu R400-W1 is only 999 yuan in the recent Double Eleven promotion. This will make the advantage even greater. If you are looking for a product with a suitable price and efficacy, then this Suning XiaoBiu R400-W1 will be a good choice.
