Express Water WH100SC filtration capacity and limitations for whole house systems

The system uses activated carbon block replacement water filters to treat the water. These filters are designed to improve water taste by capturing organic compounds and chemicals. We included the Express Water WH100SC in our comparison because it offers a high filtration capacity of 100,000 gallons. This capacity allows the unit to treat water for a family of four for roughly 180 to 270 days. Does your household use a lot of water? At 100,000 gallons, the system provides enough filtration for a large family for about 7 to 11 months. Because this is a whole house filtration system—a large unit that cleans the water for every tap in your home—knowing the specific impurities removed is vital to ensure the media handles your local water chemistry effectively. The data does not state the specific reduction rates for heavy metals like lead or arsenic, nor does it specify a maximum flow rate in GPM or a rating for high-hardness water.

What to Check Before Buying the Express Water WH100SC

• Verify if your local water source contains heavy metals like lead or arsenic, as the listed impurities do not explicitly include these.
• Confirm that your plumbing can accommodate a 1 inch inlet and outlet connection.
• Check your local water hardness levels to see if scale buildup might occur on the internal stainless-steel frames.
• Measure your home’s water pressure to ensure it meets the requirements for a whole house system without a significant pressure drop.
• Identify the location for the bypass valve to ensure you have water flow during cartridge maintenance.
