FAQs
Common questions, answered.
What is a whole-home water filtration system?
A whole-home filtration system treats the water at the main point of entry to your house, so every faucet, shower, and appliance delivers cleaner, filtered water.
How does reverse osmosis work?
Reverse osmosis pushes water through a semipermeable membrane that removes chlorine, heavy metals, fluoride, and other impurities — filtering particles down to 0.0001 microns.
How often should filters be replaced?
Whole-home filters are typically inspected annually. RO filters are usually replaced every 6–12 months depending on water quality and usage. We'll set a schedule that fits your system.
Will filtration reduce my water pressure?
No. Our systems are engineered with high-flow valves and correctly sized media beds to maintain strong, consistent pressure throughout your home.
Do you offer free installation?
Yes. Every Earnest Water system comes with free professional installation by our trained technicians.
What warranty comes with your systems?
Every Earnest Water system comes with a lifetime warranty on the equipment. We stand behind what we install.
