5 of the 22 Alabama cities we grade score below 70/100. If your city is one of them — or you just want extra protection — a certified filter is the fastest way to reduce exposure. The findings that drag a score down (lead, PFAS, arsenic, nitrate) are exactly the ones a basic carbon pitcher does not remove.
APEC ROES-50 Reverse Osmosis
Removes 95–99% of lead, arsenic, nitrate, fluoride and PFAS — the widest range of any filter type. The right choice if any city near you flags these.
