iSpring WGB32B-KS Whole House Water Filter System - Removes Heavy

In this review of the iSpring WGB32B-KS whole house water filter system, the bottom line is simple: it is best for households that want broad chemical and sediment removal without altering healthy minerals. The system's most compelling feature is its three-stage design led by a 20 x 4.5 compound second-stage filter that specifically targets chlorine, heavy metals, hydrogen sulfide and pesticides, delivering noticeably improved water taste and smell right at the point the water enters the home. For families on well water or anyone bothered by chlorine odor, this is a practical whole-home solution.

Key Features

• Three-stage filtration: A sediment first stage, a compound second stage, and a coconut shell carbon third stage work together to reduce particulates, chlorine, heavy metals and odors for cleaner water throughout the house.
• Compound second-stage filter: The FG25B-KS 20 x 4.5 cartridge targets chlorine, lead, mercury, hydrogen sulfide and other harmful chemicals to improve taste and safety.
• High flow rate: A 1 NPT inlet/outlet and up to 15 GPM flow support whole house needs including multiple fixtures running at once without major pressure loss in typical homes.
• Durable carbon and sediment media: The first-stage polypropylene captures particles down to 5 microns while the third-stage CTO uses coconut shell carbon for effective chemical and odor adsorption.
• DIY-friendly installation: The system ships with an easy-to-follow manual and online video instructions to simplify homeowner installation and routine cartridge changes.
• Large service life: Filter cartridges are rated for about 100,000 gallons, offering year-long service for an average family of four before full replacement.

Who It's For

This system is aimed at homeowners with municipal or well water who want to remove chlorine taste and smell, hydrogen sulfide, heavy metals and common agricultural chemicals across every tap. It suits families that prefer retaining beneficial minerals while eliminating harmful chemicals rather than reducing total dissolved solids.

Those who need TDS reduction, point-of-use ultra-fine filtration, or a compact under-sink filter should look elsewhere; the WGB32B-KS is a whole house solution designed for flow and broad contaminant removal rather than mineral stripping or reverse osmosis-level purity.

Pros & Cons

Pros

• Removes chlorine, heavy metals and hydrogen sulfide, noticeably improving water taste and smell.
• Three-stage design with a 5 micron sediment stage and coconut shell carbon for durable performance.
• Supports up to 15 GPM with 1 NPT connections, making it suitable for whole-home use.
• Clear DIY guidance and customer support from the manufacturer for installation and maintenance.

Cons

• Does not reduce Total Dissolved Solids (TDS), so it will not soften very hard water or remove dissolved salts.
• As with any whole house system, professional installation is sometimes chosen by users, which can add to upfront cost.
