How Whole House Filtration Works

Exposure pathways are… the ways chemicals enter your body.

Some chemicals may cause harm if they are ingested, some if they are breathed in and some if they enter through the skin. Sometimes people are exposed through a combination of exposure pathways.

An under-sink filter… protects people from ingesting the chemical by treating the drinking or cooking water only from that tap. It will not protect people from inhaling the chemical while showering or bathing, prevent the chemical from being absorbed through the skin, or protect other water faucets. Inhalation is a concern when the chemical easily evaporates from the water into the air.  Not all contaminants easily evaporate into the air or are absorbed through the skin.

A whole-house filter system… treats all water traveling to any faucet or fixture in the home. It removes the chemical before it can be ingested, breathed in, or absorbed by the skin during washing or bathing.
