What determines the right system?

A water test identifies what needs treating before a system is selected.

  • System type: point-of-use or whole-house filtration
  • Filtration technology: carbon, reverse osmosis, ion exchange or UV
  • Contaminants identified through testing
  • Household water demand and available space
  • Installation access and plumbing connections
  • Filter replacement and maintenance requirements

Whole-house filtration

Whole-house systems treat water as it enters the home. The appropriate equipment depends on the water supply, contaminants and household demand.

Does my home need filtration?

Filtration can address specific taste, odor, sediment or contaminant concerns. A water test helps determine whether treatment is needed and which technology suits the findings.

Do I need water filtration if my water is municipal?

Yes, municipal-water homes can benefit from filtration too. Public water is treated before distribution, but a homeowner may still want to address taste, odor, sediment or other characteristics measured at the tap. Not every home needs an added system. Mallick can test your water, explain the results and recommend a point-of-use or whole-home option only when it fits your needs.

Which type should I choose?

Point-of-use systems treat water at one tap, while whole-house systems serve the property. Choose based on test results and where treated water is needed.

How often do filters need replacing?

Replacement frequency depends on your system, water quality and manufacturer guidance. Hard water or high sediment may require more frequent replacement.

  • Pitcher filters: every 2 to 3 months
  • Faucet-mounted filters: every 3 to 6 months
  • Under-sink systems: every 6 to 12 months
  • Whole-house sediment filters: every 6 to 12 months
  • Whole-house carbon filters: every 12 to 24 months

How do I get started?

Start with water testing, discuss the results with a technician, and review installation and maintenance requirements. Financing is available for system installation.
