Xiaomi's latest water purifier promises "longevity water" straight from the tap

Xiaomi has added another water purifiier to its lineup, namely the Mijia Rich Mineral Water Purifier 2, the successor to the Mijia Water Purifier 2 1200G from last year. The highlight here is Xiaomi's "Bama spring" mineralization formula, a patented technology meant to replicate the water chemistry of Bama, a Chinese region associated with longevity. 

As water passes through, the unit purportedly remineralizes it with six minerals: strontium, zinc, calcium, magnesium, potassium and bicarbonate ions. Strontium is kept at or above 0.2 mg/L, the threshold Xiaomi says qualifies as mineral-water grade, without added synthetic chemicals. However, these claims have not been independently verified and should be taken with a grain of salt. 

On filtration, the new unit uses a dual-core, nine-stage system rated at 0.0001 μm, with Xiaomi citing over 99% removal rates for contaminants such as viruses, E. coli, microplastics and PFAS, alongside a reverse osmosis (RO) membrane wiith a marketed 98.5% desalination rate. This marks an incremental step up from Xiaomi's earlier Mi Home Water Purifier 2 1200G, which relied on a simpler dual-core setup that claimed to remove 145 pollutant types without published removal percentages.

Flow speed has also increased slightly, from 3.2 to 3.38 litres per minute, while the RO cartridge's rated lifespan has grown from seven to eight years. Like the 1200G, the new model also has a smart faucet with a TDS readout and app-based monitoring.

Pricing has also increased: the new purifier lists at 2,199 yuan (roughly $327), against 1,999 yuan (about $292) for its predecessor. Sales are set to begin on September 15, with an 8-year RO cartridge said to cost 1099 yuan (approx. $164) and a 2-year PPC filter priced at 299 yuan (approx. $44.50). Like the earlier model, availability appears limited to China so far, with no confirmation of an international launch.
