Cleansui’s Water Filtration Technology
Cleansui uses Hollow Fiber Membrane technology, a fiber with pores as small as 0.01 micron. This lets Cleansui filter cartridges remove extremely fine impurities such as bacteria, rust, sediment, and other contaminants invisible to the naked eye. It works together with Activated Carbon that absorbs unpleasant odors and tastes, so the water comes out clean and great-tasting.

Cleansui Filter Cartridge Life
The life of a Cleansui filter cartridge depends on the model and how much water you use. In general:
- Faucet-mount models: such as the EF101, EF201, and EF301, last about 3 months or about 900 liters depending on usage
- Countertop models: such as the ET101 and ET201, last about 12 months or 8,000 liters
- Under-sink models: such as the EU301, last about 12 months or 8,000 liters
- Commercial models: Cartridge life varies by model and water usage
Note: The stated cartridge life is an average and may vary with water quality and actual usage.
How to Replace a Cleansui Filter Cartridge
Replacing a Cleansui filter cartridge is easy to do yourself. The general steps are:
- Turn off the water: Before replacing the cartridge, turn off the water to prevent leaks.
