Find a Filter

See which water filtration technologies are effective at reducing the contaminants detected in this utility's water supply.

Carbon Filters
Filters 8 contaminants exceeding guidelines (+3 others)

Can reduce the levels of many common contaminants.

Pros
  • Lower upfront cost
  • Reduced maintenance
Cons
  • Does not remove all contaminants
Reverse Osmosis
Filters 9 contaminants exceeding guidelines (+5 others)

Can reduce the levels of many common contaminants.

Pros
  • Most effective
Cons
  • Higher upfront cost
  • Requires more maintenance
  • Wastes water
Other Considerations
Ion Exchange
PROS: Softens hard water, Reduces some contaminants
CONS: Doesn't remove all contaminants
Whole-House Filters
PROS: Useful for reducing radiologicals and TCE
CONS: Expensive to install and maintain, Risk of bacterial contamination
