Including filter system and high-performance Trichloroethylene filter.
Trichloroethylene, commonly called TCE, is a synthetic solvent that can reach drinking water when it’s released and moves through soil into groundwater. It’s widely used in industrial degreasing and can remain in the environment for long periods. Because TCE often has no noticeable taste or smell at low concentrations, Portland homeowners can’t rely on senses to detect it — testing is the only reliable way to know whether your water contains trichloroethylene.
If trichloroethylene is found in a Portland home's supply, many families prefer a treatment that protects the whole house, not only the kitchen tap. Whole-house treatment matters for everyday activities — from showering and bathing to cooking, making ice, and brushing teeth — since TCE exposure is a concern over time rather than an immediately obvious nuisance. Once testing clarifies what’s present, a whole-home strategy gives consistent protection at every fixture.
To reduce trichloroethylene where water enters a Portland residence, a whole-house granular activated carbon (GAC) filter is generally the most effective single-filter choice. GAC removes many volatile organic compounds, including TCE, by adsorbing them as water flows through a substantial carbon bed. Contact time is important, so correctly sized carbon media and proper flow design are key for meaningful removal. This style of system treats all faucets and showers, providing home‑wide coverage rather than a single-point fix.
A properly designed GAC whole-house filter for trichloroethylene should be sized for your Portland household’s water usage so the media has adequate contact time. Carbon does become exhausted, so replacement schedules should reflect your flow rates and be guided by follow-up testing when possible. Many systems also include sediment prefiltration to protect the carbon bed from clogging and channeling. If you’re focused on TCE, Mr. Pure Water can help Portland homeowners select a whole-house carbon setup that suits your water and living situation.
