What is the filtration capacity of the Express Water Whole House Water Filter System?

You must confirm your home’s average daily water usage to determine how many years this capacity will last, then plan your first media swap based on that total volume.

How the 100,000-gallon capacity of the Express Water Essential works

This 100,000-gallon figure represents the total volume the system treats before the internal components reach their limit. We selected the Express Water Essential for our comparison because it provides a 3-stage filtration process, which includes a sediment filter to trap physical particles, a carbon block to remove chemicals like chlorine, and a final stage to ensure clear water. Understanding this capacity is vital for whole house filtration because the media eventually becomes saturated; like a sponge that can only hold so much water before it stops soaking up liquid, the filter media has a physical limit to how much debris it can trap. The 3-stage designation means the capacity is shared across the system’s components. Because the system handles high-flow needs, the longevity of the media can be shortened if your local water source has a high sediment load or heavy silt, which clogs the pores of the media faster than standard municipal water.

• Verify your home’s average daily gallon usage to calculate the expected lifespan of the 100,000-gallon capacity.
• Check your local water’s sediment levels, as heavy silt or minerals will exhaust the filtration media faster than the rated capacity.
• Confirm your home’s incoming water pressure (PSI) to ensure the flow rate meets your needs, as low pressure can limit the volume pushed through the media.
• Measure the available space for the unit and the included heavy-duty stainless steel bracket and free-stand frame.
