A whole-home filter improves your water. A sediment filter in front of it makes the whole system work better, protect your plumbing and last longer.
What a sediment filter does
Sediment filters physically trap particles such as sand, rust and silt. They don't change the water's chemistry, but they stop grit from reaching your fixtures, appliances and the more expensive filter media downstream.
Why it improves your water treatment system
- Better water quality: large particles are removed before the main filter
- Longer media life: carbon and softener resin don't clog with grit
- Steady water pressure: flow rates stay high
- Appliance protection: less debris in valves, dishwashers and water heaters
