In light of the recent lead contamination in Flint, MI (USA) - I've been wondering which, if any, media are effective for removing lead from household tap water.
I currently have a custom filter system I build myself with 3 standard 10" filter housings containing (in order)
- Activated Alumina
- KDF 55 / GAC
- 0.5 micron Carbon Block
My intention at the time was to use alumina for fluoride, KDF/GAC for chlorine & chloromine, and the carbon block as a final stage for taste and any particulate that came through from the first two filters. I know these technologies can filter more than the above but my question is, are any of these capable of removing lead and either way, is there another media that would be good to consider adding in to the system for this purpose?
