Whole-home pre-filter system for sediment control

The Water Doctor Guardian Pre-Filter System is a point-of-entry filter housing system for homes that need sediment filtration before water reaches fixtures, appliances or other treatment equipment. It can be configured with different housing sizes and cartridge types based on the home’s water conditions.

Best for

  • Homes with sand, silt, rust particles or cloudy water
  • Customers adding pre-filtration before a softener, RO system or UV system
  • Well water or older plumbing applications where sediment is common
  • Homes that need single, dual or triple housing configurations

Key benefits

  • Point-of-entry filtration for the main water line
  • Multiple housing sizes including 2.5" and 4.5" options
  • Compatible with sediment and carbon cartridges depending on selected setup
  • Useful before other water treatment equipment such as softeners and UV systems
  • Customizable configuration for different water usage and flow requirements

Choosing a setup

Choose the housing size and cartridge type based on sediment level, water flow needs and whether the system is used alone or before another treatment device.

Maintenance

Cartridges should be replaced regularly. Replacement frequency depends on sediment load, water usage and cartridge type.
