dibromochloromethane, and bromoform.

Difference in usage period due to water quality
A hollow fiber membrane filter is built in the cartridge to remove fine dirt.
Therefore, the usage period becomes shorter for water containing more substances that
cause clogging.

Radioactive substances cannot be removed.
Note
●
For regular tap water, the clogging timing may differ significantly depending on the water
quality (turbidity, iron mold, etc.) and water pressure.
