Although Midea is not specialized in the field of water purification, it has been laid out in the water purification market as early as 2001, and has a lot of right to speak in the water purification industry, it is the leader of industry standards such as "reverse osmosis water purifier" and "ultrafiltration membrane water purifier", and has also participated in the drafting of the mandatory national standard for the water efficiency grade of reverse osmosis water purifier, and its market share has been ranked first for many years.
Midea water purification equipment R&D and production are mainly operated through a joint venture company jointly created with South Korea's Qinghu NAIS, in addition to the main brand of Midea, there are also two sub-brands of Beverly and Hualing, one is mainly high-end, and the other is mainly low-end. These two brands are also easy to judge by the model, Beverly and Mei models both start with QZBW, and Hualing starts with WAH, the higher the last two digits in the model, the better.
In Midea's high-end product line, it is worth buying Beverly QZBW20S-16, its biggest feature is the automatic flushing function, which can be set by the button on the front panel, such as 7 days, 15 days or 30 days, which is more convenient, and will not accumulate dirt due to forgetting to clean up, of course, the automatic cleaning function also needs to install a battery and an external sewage pipe (included in the package), which needs to be replaced regularly.
The Beverly QZBW20S-16 is equipped with a water pressure gauge that can detect the water pressure in real time, and can be treated with corresponding pressure control measures when the pressure is too high or too small, which is a standard feature of high-end products. The official claim can prevent 150,000 times of water hammer, and the shell is 55kg explosion-proof, which has good compressive resistance.
In terms of filtration effect, Beverly QZBW20S-16 is also at the current mainstream level: 316 stainless steel filter is more corrosion-resistant than common 304 stainless steel; Flow rates up to 3 tons per hour; The filter accuracy is 40-60 microns, which is also the mainstream at present. However, it should be noted that the accuracy advertised by most manufacturers is actually the accuracy of the smallest part of the mesh, and the actual filtration accuracy is slightly larger, because the size of the mesh is difficult to achieve complete unity, and only an approximate range can be taken, which requires more attention, especially the propaganda of 20 micron accuracy, which is basically playing with words.
Beverly QZBW20S-16 has excellent configurations and is priced at about 800 yuan. Although the installation of the pre-filter is not complicated, Beverly still provides free on-site design and installation services, in addition to a free 5-year warranty for core components and a 3-year warranty for the whole machine, which can be said to be quite intimate.
If you don't need the auto-flush function, you can also consider the Midea QZBW20S-12, which is similar to the technical standards adopted by Beverly, which is positioned as a high-end model. Like Beverly QZBW20S-16, the minimum accuracy of its filter is 40 microns, the flow rate is 3 tons per hour, and it has a double-sided rotary scraping cleaning function, and the price is about 500 yuan, which is cost-effective. However, Midea only provides a 1-year warranty and a 3-year paid on-site maintenance service, which is a bit uninteresting compared with the warranty of its own Beverly.
Hualing's pre-filter is basically about 300 yuan, and the product model WAH-160 has a configuration of 600 yuan at this price: 40 micron precision filter, 3 tons of large flow per hour, with double-sided scraping and siphon recoil functions, and a water pressure gauge to monitor water pressure in real time. The price is 399, which is very cost-effective.
