Chlorine / Chloramine (Disinfectant Residual) in your water
Is Chlorine / Chloramine (Disinfectant Residual) in drinking water dangerous?
It depends on the level and how long you're exposed. The EPA legal limit (MCL) for Chlorine / Chloramine (Disinfectant Residual) is 4 ppm. Meeting the legal limit isn't the same as zero risk — test your water to know your level.
How do you remove Chlorine / Chloramine (Disinfectant Residual) from water?
Chlorine / Chloramine (Disinfectant Residual) is treated by Reverse Osmosis and Whole-House Carbon Filter. Choose a system independently certified to NSF/ANSI standards to reduce Chlorine / Chloramine (Disinfectant Residual), and test your water first to confirm the level.

Health effects
Chlorine and chloramine are added by utilities to disinfect drinking water. Safe at regulated levels, but they cause taste and odor issues and can form disinfection byproducts. Carbon filtration removes them. EPA maximum residual disinfectant level (MRDL) is 4 ppm.
The health-based goal vs. the legal limit
The federal legal limit (MCL) is the maximum allowed by law. The EPA health goal (MCLG) is the level below which no health risk is expected — it is non-enforceable and often stricter than the legal limit.

What removes Chlorine / Chloramine (Disinfectant Residual)
Semipermeable membrane filtration
Reverse Osmosis
Pushes water through a fine membrane that removes the dissolved solids most filters miss.
Look for: NSF/ANSI 58 certification
How it works→Activated carbon adsorption
Whole-House Carbon Filter
A point-of-entry carbon bed that strips chlorine, chloramine, and chemical taste from every tap.
Look for: NSF/ANSI 42 certification
