Alkaline Mineral Water: The Smart Way Your water is mineralized totally naturally with our Active Mineral technology. Our minerals are ionically activated so your water picks up more mineral content as it passes through five types of mineral rocks. This is the same way that the healthiest natural springs on Earth add minerals. Calcium, Potassium, Magnesium, and other minerals your body needs, right in your waterA great source of antioxidants to help you recover energyUp to 20% more oxygen than regular waterHigher pH helps balance your water and keep your body at a healthy pH Alkaline Mineralization Make the purest alkaline mineral water with your own home alkaline filter set. Great in the kitchen: Improve the taste of your cooking, coffee, ice, and drinks. Experience true Reverse Osmosis purification. Your filtered water is made healthier with Alkaline mineralization. The Express Water Alkaline Filter adds essential minerals that filtration may remove from your water. The Alkaline filter adds minerals like calcium, potassium, and magnesium to your water. Improves the pH of your water, adds up to 20% more oxygen than normal water, and adds antioxidants to help you recover energy. Sediment Filtration Reduces sand, dirt, silt, dust, scale, rust, and other sediments.High capacity design captures more impurities than other filters.Made with precision packed 100% pure food-grade polypropylene microfiber.Fast 1 GPM filtration.Multi-Layered Smart Filter: Made with 4 distinct layers. The outer layers catch the coarsest impurities and the inner layers catch finer impurities. This means your filter lasts longer, catching more sediments before it needs to be replaced. Carbon Filtration Captures more impurities than other carbon filters with efficient laboratory vacuum-heated carbon granules from cleaned coconut husks.High rejection rate of: chlorine, volatile organic chemicals, halide, and chemicals causing bad tastes and odors.GAC & ACB: Precision thermal bonded cap with industrial sealed silicon ring prevents leaks.GAC & PAC: Equal Flow Technology: Efficiently arranged carbon granules create full coverage filtration for longer-lasting filters, giving you the best value in filtration.ACB: Efficiently packed carbon granules maximize your filtration surface area which means your filter lasts longer and filters more. RO Membrane 100 Gallons Per DayCompact, high-density, graded reverse membrane layers make this the highest impurity reduction rated Reverse Osmosis Membrane.Catches impurities as small as 0.0001um (1/10,000th of a micron) including various living impurities.High rejection rate of: chlorine, total organic carbon (TOC), benzene, industrial solvents, turbidity, total dissolved solids (TDS), and chemicals causing bad tastes and odors.Density grading of the membrane layers gives your filtration the most surface area which means your filter catches more impurities and lasts longer giving you the best value in filtration. Universal Filtration Fully compatible high quality mineralization for any standard 10” housing.Number of filters: 1 SED, 1 GAC, 1 ACB, 1 ROM (100 GPD), 1 ALK, 1 PAC.Life Cycle (SED, GAC, ACB, ALK): We recommend replacement every 6 months or earlier.*Life Cycle (ROM, PAC): We recommend replacement every 1 year or earlier.**Life cycle is based on national average water quality, the water in your area may require more or less frequent filter changes.

Max temperature 100­­°F (38°C). Note: You will need an install kit (fittings and brackets) if you are installing a new ALK filter for the first time and not replacing an old filter. Long lasting filters of the highest capacity give you the best value in filtration. The water is cleaner and more convenient than any pitcher, faucet filter, or countertop systems. Express Water’s Reverse Osmosis Water Filter Set is the complete filter solution for your drinking water.
