just replaced the filter element for the ultrafiltration purifier (whole house purification) that had been used for ten years at home, so by the way, the RO membrane water purifier that had been used for more than three years was also replaced. Let’s talk about personal thinking when purchasing, and let’s talk about it.
This year's 618, Xiaomi water purifier has a bizarre design of double RO membrane, I personally feel very inexplicable. The first is PPC (219 yuan/piece); the second is RO-200g (299 yuan/piece); the third is RO-800g (899 yuan/piece). It is said that the wastewater ratio can be increased to 3:1. Interestingly, I haven't seen other water purifiers with this design. The first RO membrane works more like the original ultrafiltration. But what can be done with one membrane, why use two membranes? RO membranes are more expensive and more fragile than ultrafiltration. (3) Pay attention to the rated total water purification capacity of the filter element (machine) . The current market average price of reverse osmosis water purifiers is around 2000, with little difference in function. Its price is often closely related to the quality of RO membranes, and cheap ones are often not the best choice. At present, the general machine claims that the RO membrane can be used normally for three years. Unfortunately, this data is only the manufacturer's self-estimation. The real hard core is the rated total net water volume, which is the truly effective design service life of the filter element. Suppose a family of three drinks less water at home during weekdays and more on holidays. On average, one person should drink one liter of water a day. Then 3L x 365 days x 3 years = 3285 liters of water (more than 3 tons). In general, the nominal rated total net water volume of the RO membrane is about 2400L (2.4 tons), which means that its design life is difficult to guarantee the minimum consumption of the family for three years. In other words, although this water purifier claims to not need to change the core for three years, it is actually impossible to do so, so the whole machine is cheap and the filter element is cheaper. The concept of rated total water purification capacity was only noticed when I introduced A.O. Smith high-end water purifiers on the SMZDM website a few years ago. At that time, I was impressed that its total water purification capacity was 8~9 tons, which could last for five years. No need to change the core. For example, when I bought the Terjeen M20, I only noticed that the price was affordable, the filter element was cheap, and the warranty was ten years. I didn't pay attention to this parameter. It was only later found that this index was not written in the parameter table of the store advertisement page at all. After inquiring to the customer service, I found out that the total amount is about 2400L. So when 618 changed the water purifier this time, I paid special attention and compared this index. Sure enough, although the filter element of A.O. Smith's Ganite water purifier may be slightly more expensive than the domestic water purifier, its nominal rated total water purification volume is also the highest among similar products in the market. The 550~600g machine is 4800L, and the new 800g machine I bought with a larger flow rate is 5500L, so the total amount of drinking water for a family of three for three years is still guaranteed. Interestingly, some manufacturers paid attention to this new trend of smart consumers, so they played a more "smart" edge ball. The water purifier of a well-known home appliance manufacturer in China shows the total water purification volume of 8000L in large characters, and then turns the pen, and uses small characters to indicate that the total water purification volume is the sum of the two totals of pure water and purified water. The final parameter table shows The rated total water purification capacity of RO membrane is actually only half: 4000L, which is a bit of a downturn! In the next article, I will also talk about the service quality of this manufacturer's air conditioner (─.─||| (4) water output . For ordinary families, in addition to the above concerns, the water output is the most affecting experience. The M20 I bought before is actually not broken. After changing the core, it can continue to be used normally, but the water output is too small. Every time I put water, I need to wait for a long time. The use experience is bad. just replaced the filter element for the ultrafiltration purifier (whole house purification) that had been used for ten years at home, so by the way, the RO membrane water purifier that had been used for more than three years was also replaced.

After changing the core, it can continue to be used normally, but the water output is too small. Every time I put water, I need to wait for half a day. The experience is bad. Although its nominal flow rate is 400g,But after installation, it is found that the water output is smaller than the general 400g, and the customer service said that it is the relationship of water pressure. Looking back now, no wonder the RO membrane filter element was so cheap. Considering that my wife is now a tea master, and usually drinks a lot of tea, the family of three are all water buffaloes, so I decided to buy the CXR800-T1 800G water purifier Dabai pro from Janite. The purchase channels of Janite water purifier include Xiaomi Youpin/Tmall flagship store, etc. The difference is that when you buy it in Xiaomi Youpin, WIFI is linked to the Xiaomi Home APP; if you buy from the Tmall flagship store, it is linked to the Tmall Genie APP. Because it was less than 2399 yuan after the Tmall 618 event, I finally chose to place an order on Tmall on June 1. The total price is similar to that of ordinary domestic water purifiers, and the first and third-stage filter elements can be sent for three years without core replacement. Although the RO membrane filter element (780 yuan) is expensive, considering that the life of the filter element can be effectively extended in the case of pre-ultrafiltration in my home, after joining the membership, I can purchase the filter element at a 12% discount, so the annual cost is completely acceptable. SF Express, the arrival is relatively fast. The WeChat public account directly contacted the installation the next day. The master from is a very handsome young man. He unpacked and installed the filter element very quickly. There are a total of three filter elements in the package, just plug them in and turn them half a turn, which is convenient. The climax is coming. After the young man looked at my original M20 pipeline, he pointed out an unreasonable part of wastewater discharge, which is very powerful. Don't look young and handsome, the key is good craftsmanship (^o^) The volume is smaller than the original M20, it is easier to place under the kitchen, the whole machine is guaranteed for three years, and the core components are five years, so it is clean. The little master thought very thoughtfully. He connected my waste water to the waste water pipe of Lisheng Ultrafiltration, and installed a one-way valve (free) to prevent the recoil of the ultrafiltration waste water.awesome. is installed, the TDS of tap water is 189, and the pure water of Janite is 8~9. I feel that the biggest change is the water output. Now the faucet basically only needs to be opened halfway. The old man in the family laughed, and finally don’t have to wait stupidly (^o^) Video: Janite household 800g water purifier relies on the mature experience of A.O. Smith factory to provide solid internal quality and high-quality installation The service greatly improves the user experience. Since using it, I often deceive that my wife looks at me with a little more praise, less white eyes, and great kindness (^o^) Amin "Original" is installed, the TDS of tap water is 189, and the pure water of Janite is 8~9.
