[PROTECT YOUR SKIN AND HAIR] ----- Most of the tap water we use every day contains chlorine. Chlorine damages skin and hair and cannot be removed by heating. The water filter cartridge can absorb chlorine from the water, protecting the health of skin and hair. Total Dissolved Solids (TDS) such as limescale would not be filtered out. [DOES NOT REDUCE WATER PRESSURE] ----- Water pressure has a major impact on the comfort of our shower. As long as the water pressure is normal, the water pressure will not be reduced when passing through the limescale filter, thus ensuring shower comfort. The limescale filter also filters out fine impurities, odors, and chlorine in the water. [INSTALL IN MINUTES] -----No tools required, our shower filter is suitable for 1/2" water pipes. As long as the water inlet and outlet are clearly defined (see product images), you can install it very quickly. Before installation, the rubber rings must be inserted correctly. [IMPACT RESISTANT & LEAK-PROOF & NON-SLIP] ----- All metal water filter housings are equipped with two large inner rubber rings for light shock resistance. Each shower filter is equipped with two leak-proof rubber rings. A properly placed rubber ring can prevent leakage (if water still leaks, please wrap it with Teflon tape). [PROTECTION AND HEALTH] ----- 15-stage filters contain 12 different filter materials, filter out fine impurities, odors, and chlorine, protect the skin from harmful substances in the water, and contain vitamin C spheres in the filter. When water passes through the filter cartridge, a small amount of vitamin C is produced to make your skin and hair healthier and more beautiful. to make more energetic.
