Lead in your water
Is Lead in drinking water dangerous?
It depends on the level and how long you're exposed. The EPA legal limit (MCL) for Lead is 15 ppb. The EPA also sets a non-enforceable health goal (MCLG) of 0 ppb. Meeting the legal limit isn't the same as zero risk — test your water to know your level.
How do you remove Lead from water?
Lead is treated by Reverse Osmosis and Whole-House Carbon Filter. Choose a system independently certified to NSF/ANSI standards to reduce Lead, and test your water first to confirm the level.

Health effects
Lead rarely originates at the treatment plant; it leaches from older service lines, solder, and brass fixtures. There is no safe level of lead, and it is especially damaging to the brain development of children. The federal value is an action level rather than a health-based limit.
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 Lead
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
