Most effective option for removing lead. Point-of-use under-sink systems.
Carbon block filters specifically certified for lead. Available as pitchers, faucet-mount, or under-sink.
Very effective but slow. Good for drinking water only.
No. EPA and health experts agree there is no safe level of lead, especially for children. The action level of 15 ppb triggers required treatment, not a safety threshold.
Lead typically enters water from your home plumbing, not the water source. Corrosion of lead pipes, solder, and fixtures dissolves lead into water, especially when water sits overnight.
No. Boiling actually concentrates lead by evaporating water. Only filtration can remove lead.
