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. The PP filter lasts 6-8 months, the UF filter lasts 12 months, and the CT filter offers an
