The iSpring WGB32BM is a solid choice if you want to improve your home's water quality by reducing iron, manganese, chlorine, sediment, and odors throughout your entire house. It uses a 3-stage filtration process: a sediment filter, a carbon block filter made from coconut shell for chlorine and chemical removal, and a specialized iron filter that lasts longer than typical greensand filters. This system handles up to 15 gallons per minute, which means it won’t noticeably slow down your household water flow.

The filters have a good lifespan, treating up to 100,000 gallons each—roughly a year for a family of four—so maintenance won’t be frequent. Installation is designed for DIY with clear instructions and support, though it’s a permanent setup attached to your main water line, so some plumbing work is needed. Its size is fairly compact for a whole house system, but it weighs 55 pounds, so consider space and handling during installation.

Unlike reverse osmosis systems, this filter does not remove total dissolved solids (TDS), meaning beneficial minerals remain in your water. For those prioritizing mineral removal, an additional system may be necessary. Customer support and warranty are reassuring, with a one-year warranty and lifetime tech help from a U.S. team. This system is especially suited for households with issues related to iron and manganese, providing thorough filtration with reasonable maintenance and strong flow performance.

Filtration Stages
The multi-stage filtration effectively eliminates sediment, chlorine taste, odors, and reduces hard water scale buildup, keeping fixtures spotless and appliances protected.
Filter Type
With proper adjustments to filter micron ratings, the system can be customized to specific water conditions for optimal results.
Flow Rate
Water pressure remains strong with no leaks or drops, ensuring everyday water use feels natural and uninterrupted.
Contaminant Removal
The filter system successfully tackles tough well water problems such as sulfur smell and heavy sediment, making it suitable even for challenging water sources.
Installation and Maintenance
Installation is straightforward with clear instructions, and routine maintenance is simplified by features like the spin-down sediment filter for easy flushing.
Size and Space Requirements
Despite its size and weight, the system’s compact design fits well in home setups and supports DIY installation with some plumbing skills.

The iSpring WGB32B is a whole house water filter system designed to reduce chlorine, sediment, odors, and other common water contaminants, making it suitable for homeowners wanting cleaner water throughout their house. It uses a 3-stage filtration process: a 5-micron sediment filter followed by two carbon block filters made from coconut shell carbon, which helps remove up to 99% of chlorine and improves taste and odor. The system supports a strong flow rate of up to 15 gallons per minute, so it shouldn't noticeably slow down your water pressure, which is important for everyday use.

The filters are fairly large (20 inches) and have a long lifespan of about one year or 100,000 gallons, meaning less frequent replacements and maintenance. Installation is designed for DIY users, with clear manuals and helpful videos, making it doable without professional help, though some basic plumbing skills might be needed. The system is tankless and reasonably compact, but it does weigh around 45 pounds and takes up some space—something to consider if your installation area is tight.

One plus is that it keeps beneficial minerals in the water, unlike reverse osmosis filters, so your water won’t feel flat. However, if you want to remove dissolved solids or need extremely pure water, this filter won’t do that. Also, while it effectively targets chlorine and sediment, it may not remove all types of contaminants like heavy metals or bacteria. This system is a strong choice for families seeking improved water quality and taste with manageable upkeep and installation.

Buying Guide for the Best House Water Filter System

Choosing the right house water filter system is crucial for ensuring that you and your family have access to clean and safe drinking water. The right system can remove contaminants, improve taste, and provide peace of mind. To make an informed decision, it's important to understand the key specifications and how they align with your specific needs. Here are the key specs to consider when selecting a house water filter system.
Filtration StagesFiltration stages refer to the number of steps the water goes through to be purified. More stages typically mean more thorough filtration. Systems can range from single-stage filters, which are simpler and may only remove basic contaminants, to multi-stage systems that can remove a wide range of impurities including sediments, chlorine, heavy metals, and bacteria. If your water source has multiple contaminants, a multi-stage system is likely the best choice.
Filter TypeDifferent filter types are designed to remove different contaminants. Common types include activated carbon filters, reverse osmosis filters, and UV filters. Activated carbon filters are good for removing chlorine and improving taste, reverse osmosis filters are effective for removing a wide range of contaminants including heavy metals, and UV filters are excellent for killing bacteria and viruses. Choose a filter type based on the specific contaminants present in your water.
Flow RateFlow rate measures how much water can be filtered per minute, usually in gallons per minute (GPM). A higher flow rate means more water can be filtered quickly, which is important for larger households or if you use a lot of water. For smaller households or less frequent use, a lower flow rate may be sufficient. Consider your household size and water usage to determine the appropriate flow rate.
Filter LifespanFilter lifespan indicates how long the filter will last before it needs to be replaced, usually measured in gallons or months. Longer lifespans mean less frequent replacements and lower maintenance costs. However, filters with longer lifespans may be more expensive upfront. If you prefer convenience and lower maintenance, opt for a filter with a longer lifespan.
Contaminant RemovalDifferent systems are certified to remove different contaminants. Look for certifications from organizations like NSF or WQA, which test and verify the effectiveness of water filters. Make sure the system you choose is certified to remove the specific contaminants found in your water. You can usually get a water quality report from your local water supplier to identify these contaminants.
Installation and MaintenanceConsider how easy the system is to install and maintain. Some systems require professional installation, while others can be installed by a handy homeowner. Maintenance includes replacing filters and possibly cleaning the system. If you prefer a hands-off approach, look for systems that are easy to maintain or come with professional service options.
Size and Space RequirementsWater filter systems come in various sizes, and it's important to ensure that the system you choose fits in the space you have available. Measure the area where you plan to install the system and compare it to the dimensions of the system. Also, consider the ease of access for maintenance and filter replacement.
