Double “Big Blue” Cartridges, 4.5" X 20"

Cartridges in this category are used almost exclusively for point-of-entry, or “whole house” applications. They are particularly valuable as sediment filters for wells or dechlorination filters (carbon cartridges) for city water applications.

If you’re comparing prices, remember that cartridges in this category are heavy, and we pay shipping.
