You do not need to buy an expensive all-in-one solution. [400 gallons per day] The high-quality reverse osmosis membrane of filters can produce 400 gallons of purified water per day (16.6 gallons/63.1 liters/hour). Recommend 8 cups of 8 ounces (about 226.8 grams) of water, 1 gallon (about 3.8 liters) (about 3.8 liters) of water. One gallon of water can be obtained in about 3 minutes. You only need to use this RO membrane to open the tap of the RO purifier to get drinking water. [High pollutant rejection] Remove up to 97% of all dissolved solids from water. This membrane is only 0.1 nanometers, 50 times smaller than heavy metals and viruses, and about 5000 times smaller than bacteria. Therefore, these reverse osmosis membranes can easily remove heavy metals, harmful minerals and other soluble salts from water, ensuring safety and non-toxicity. Enjoy water with confidence! [Performance and quality test] RO membrane adopts the most advanced membrane membrane technology and manufacturing process. The reverse osmosis membrane is made of high-quality polyamide membrane composite material, ensuring that you get filtration and surface area coverage, allowing you to enjoy high-quality taste. [universal compatibility] 400 GPD RO membrane is a universal standard size: 12inch total length, 3inch diameter (suitable for common housing). These reverse osmosis membrane elements are compatible with most reverse osmosis purifiers on the market. This kind of reverse osmosis membrane can be placed CSM, FS-TFC, Axeon, Dow FilmTec, GE and other 3012-400 GPD model membranes. Friendly design and easy installation.
