Why Cleansui
Water filtered to 0.01 micron by a hollow fiber membrane
Filters out contaminants, bacteria, and germs while keeping beneficial minerals in the water — hollow fiber membrane technology from Mitsubishi Cleansui of Japan.

Hollow Fiber Membrane

8,000
L / year · Water filtered per cartridge (countertop model)
Install it yourself — no technician needed
Just twist it onto your faucet — no plumbing or wiring
Faucet-mount models available
Ideal for dorms, condos, and rentals where permanent installation isn’t an option
Easy to move
Moving to a new room or home? Just take it with you and reinstall it.
Real test results
Removes rust completely
Activated carbon alone leaves rust behind, but after passing through the hollow fiber membrane, the water comes out perfectly clear and clean.
