iSpring F12WCB32 Whole House Water Filter Replacement Set

Why iSpring

Located in Atlanta, Georgia for over a decade, iSpring Water Systems LLC is a family-owned company specializing in water filtration systems. We aim to make high-quality drinking water accessible to all households.

PP Sediment filter

Stage 1: Sediment

Used as the first stage of defense on the system, the filter achieves filtration down to 5 microns and removes dirt and other various larger-sized particles that may clog the following filters from the water.

Carbon Block filter

Stage 2: CTO Carbon Block

The second stage houses a 5-micron CTO coconut shell carbon block filter. It uses high-quality coconut shell carbon and highly compact fabrication tech for maximum filtration efficiency and filter life.

Carbon Block filter

Stage 3: CTO Carbon Block

Knocks out residual bad tastes and odors. Two CTOs combine to deeply remove up to 99% of chlorine and are highly effective on organic chemicals like pesticides, herbicides and industrial chemicals.

Please read before purchase

Safe Water For the Ones You Love

The filter set is able to remove up to 99% of chlorine from water as well as sediment, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants.

All filters have a capacity of 30,000 gallons of water, enough to supply a family of four with clean water for half a year (depending on your water quality).

Save on your water bill - the filters won’t produce any wastewater.

The filters are specially designed for a high water flow: up to 12 gallons per minute.

Fits iSpring WCB32C & WCB32O 3-stage whole house systems or any 20” x 2.5” filter housings

Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
