Shapure Standard Alkaline Filter and Mineral Cartridge 100% Food Graded ABS Plastic for RO Water Purifiers (Standard Alkaline Filter)

The product is very good and healthy, the water turns blue with ph indicator provided clearly indicating alkaline water.Installed it in final phase when water entering the water tank.

Very nice product at very reasonable price

Quality is bad, after 3 days, pH comes to same old as was earlier... Useless after 3 days.

Though this mineral / alkaline cartridge will not fit inside Pueit cabinet due space constraints but there is small hole on the back side of the cabinet from the inlet / outlet 1/4 pipe can be transferred and fix the mineral cartridge without much hassle .. my tap water TDS is 495 ppm above and after RO process it comes to 25 - 30 ppm (which is semi acidic) .. after fixing mineral cartridge I am getting now 185 ppm TDS and after testing with testing drops I am getting semi violet color (PH test) and complete pink color (negative ORP test) .. in other words I am having peace of mind for not consuming acidic RO water .. now time will tell the life span of this mineral cartridge... very Happy 😊

Product seems to be Ok. ORP testing kit is missing. Only pH testing kit is in the package. There is no seal for the packaging.Initially, the produced water had pH around 10, which was concerning, after flushing more than 100 litres of water, pH is now around 8-9.After around 1 week of usage, pH is now between 7-8.Water tastes little muddy.Overall it's ok ok product.Will have to see how much beneficial.
