1. Convenient replacement: RO membrane filter size standard, easy to install and replace, replacement cycle of 6-12 months, stable and durable. 2. Material: the shell is made of food-grade material, wear-resistant and impact-resistant, with strong load-bearing capacity, safe and reliable. 3. Excellent performance: the internal use of special materials, with good chemical corrosion resistance and heat resistance, higher density, stronger adsorption capacity. 4. Universal design: reverse osmosis universal RO membrane filter, suitable for most brands, no need to worry about the problem of connection error. 5. Working principle: the use of hydrostatic pumps to generate high pressure, so that water molecules and ionic minerals through a layer of reverse osmosis membrane intercepts water.
