This stainless steel 3 stage filtration system is currently the most popular type of filter. Unlike common plastic systems on the market, the Waterdrop 3-stage stainless steel water filtration system is made of lead-free stainless steel, which makes the system resistant to corrosion and compression. It is durable, strong, and less prone to cracking. At the same time, the thick sealing ring in the cap prevents leakage.
This Waterdrop 3-stage undersink water filter has 6 layers of premium filtration material, including non-woven fabric, PP cotton, activated carbon block, and an ultrafiltration membrane. The 0.01μm precise ultrafiltration membrane filters out most harmful substances larger than 0.01μm, such as rust, sediment, chlorine taste and odor, benzene, bacteria, and colloids. It can also partially reduce algae, chloride, copper, lead, and mercury. The activated carbon block and PP cotton effectively reduce chlorine, heavy metals, chemicals, cysts, odor, rust, and large particles in your water while improving the taste.
The Waterdrop 3 stage water filter system has recyclable housing. You need to replace only the inner filter. The system can last for a long time.
