> The cheapest way to lower your risk of lead exposure is to install an RO filter That’s much more expensive than the average NSF-listed filter. I believe most of them work by ion exchange, and they are a lot simpler and cheaper than RO. Get RO if you have serious hardness issues or taste issues that are not mitigated by a good NSF-listed filter with a carbon stage. https://www.nsf.org/news/concerned-about-lead-drinking-water-choose-filter-certified-to-reduce-lead https://www.nsf.org/news/concerned-about-lead-drinking-water... > if you believe there are lead pipes Just test your water. Even without lead pipes, lead solder on copper pipes can be a problem. Or lead in city pipes. Or anything made out of non-“lead free” brass or bronze. (Some of the latter has a shockingly high proportion of lead in the alloy.)
