- [Selected materials] The lead-free 304 stainless steel material makes the stainless steel 3 stage filtration system resistant to corrosion and compression. The thick sealing ring in the cap prevents leakage.
- [Efficient filtration] 6-stage filtration layers filter out most harmful substances larger than 0.01 μm. The 0.01 μm precise ultrafiltration membrane reduces chlorine, heavy metals, chemicals and more.
- [Recyclable housing] You don’t need to replace the stainless-steel housing. Just replace the inner filter once the filter expires. The PP filter lasts 6-8 months, UF filter lasts 12 months, and CT filter offers an ultra-long life of up to 24 months, which reduces replacement frequency. It ultimately helps to save money, while protecting the environment.
- [Faster water flow and easy installation] The stable flow rate can get as high as 1.59 GPM. You can connect the system directly to your home faucet without drilling a hole on the countertop.
- [Multiple arrangement options] The user-friendly innovative design allows the system to be hung on the cabinet wall or placed on the floor. Click here to compare our undersink filtration systems.
