Key item features
- Effective Filtration: This two-stage whole house water filter system utilizes a 5-micron polypropylene sediment filter and a CTO filter to reduce 99% chlorine, chemicals, sediment, taste, and odor.
- Impressive Capacity: The 10"x4.5" replaceable filters provide up to 50,000 gallons of clean water annually for a family of four, with 1-inch inlet/outlet ports for fast flow and minimal pressure loss.
- Simple Installation: The system comes pre-assembled on a mounting bracket for DIY installation, including a filter wrench and pressure release valve for easy filter changes.
- Mineral Retention: Unlike RO systems, this filter retains beneficial minerals in your water by not reducing Total Dissolved Solids (TDS).
- Comprehensive Protection: It delivers clean, fresh water to every faucet and helps extend the lifespan of water-using appliances by preventing sediment and scale buildup.

About this item
Product details
"The iSpring WGB21B 2-Stage Whole House Water Filtration System is an excellent ""point of entry"" filtration solution for smaller homes or limited spaces. Unlike ""point of use"" systems, this whole house water filter ensures that water from every outlet in your home is filtered, providing up to 50,000 gallons of clean water for the entire family. The iSpring WGB21B 2-Stage Whole House Water Filtration System is a reliable and efficient choice for maintaining clean and healthy water throughout your home."
- Two-Stage Effective Filtration The whole house water filter has a 1st-Stage premium 5-micron polypropylene sediment filter (FP15B) that captures dirt, sand, silt, dust, rust, and scale particles, using high-quality coconut shell carbon and highly compact fabrication tech,2nd-stage CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes over 90% of chlorine, and is highly effective on VOCs like pesticides, herbicides, and industrial solvents.
- Superb Filtration Capacity 10"x4. 5" replaceable whole house water filters can provide up to a full year of clean water(up to 50,000 gallons) for a family of four. 1-inch inlet and outlet ports allow fast water flow with less pressure loss. Fine PP sediment filter and premium quality CTO filter not only bring clean and fresh water to every faucet in your house but also help prolong the lives of your water-using appliances and protect plumbing from sediment and scale buildup.
- Easy Installation and Filter Change The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included making routine filter changes easy and quick. A pressure release valve allows for the release of built-up pressure when changing filters. Refer to our manual and/or YouTube videos to Install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family.
- Retain Valuable Minerals Unlike an RO system, this system will NOT 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.

Good product
Amazing, a little large than I thought, only downside is that you have to change it out every 6 months, but I’ll come back and share as time progresses.
