With more than 70,000 product categories, 3M has a strong branch of 3M's water purification business, and with its high brand awareness and smooth sales channels, 3M has successfully occupied a place in China's water purification market.
 
As RO reverse osmosis water purifiers gradually became the mainstream of the market, 3M finally kept up with the pace of development of the water purification industry and introduced RO reverse osmosis products to the market, and currently only the R8-39G model is available. The R8-39G is not produced by 3M's Guangzhou factory, it is produced by Xiamen Jianlin Company, which is also one of the main foundries of Philips water purifiers, and the product quality is guaranteed. In addition, 3M's other water purification products actually have a fairly average purification performance, and are only recommended for consumers who do not have direct drinking water needs and live in areas with better water quality.
 
R8-39G adopts the industry's top Dow RO reverse osmosis membrane, with a water purification flow rate of 400G and a cumulative water purification of more than 4000L, and the overall water purification performance is very good. Although R8-39G adopts a four-stage filtration scheme that has been criticized by industry insiders, the second-stage activated carbon is wrapped in a composite filter element of PP cotton, which effectively prevents the leakage of activated carbon powder and clogs the RO membrane, which is more comprehensive than the simple activated carbon filter solution.
 
Although R8-39G adopts the traditional appearance modeling, the design is obviously integrated into the style of modern home products, the body with pure white as the main color appears simple and elegant, the metal coating of the middle component enhances the overall appearance of the fuselage, the rounded transition of the edge sweeps away the rigid visual experience of the traditional water purifier, the built-in LED light display is attached to the 24-segmented ring life lamp, which can accurately display the remaining life of the filter element, which is not only practical, but also enhances the sense of science and technology of the product, and the overall design level is good. As for the price, R8-39G is generally around 4500 yuan, compared with similar competing products, the cost performance is average.
 
It should be pointed out that the vast majority of 3M's water purifiers are in the category of microfiltration grade, although in the propaganda 3M said that this kind of product is a "mineral machine", which can retain the mineral elements in the water after filtration, but if the tap water is polluted by heavy metals, heavy metal ions will also be retained, which is not quite in line with China's water pollution situation, 3M's microfilter has passed the NSF No. 42 residual chlorine removal certification and NSF No. 53 cyst interception certification, and the product is suitable for areas with good water quality. It is used to improve the taste of tap water, but from the perspective of safe drinking water, the filtered water of the microfilter should be boiled before drinking. If there is a need for direct drinking water, the R8-39G is currently the only ideal choice.
