A point of entry (POE) system treats water at the main supply line as it enters a building, improving water quality for every faucet, fixture, and appliance. POE systems can remove sediment, chlorine, metals, or bacteria and are often implemented as whole-house filters, water softeners, or UV treatment systems. They differ from point-of-use systems, which treat water at a single faucet or appliance.

What does a point of entry system do?
It treats all water as it enters the building so every fixture receives filtered or softened water.

POE treats all incoming water; POU treats a single outlet.
A family with hard water installs a whole-house softener at the entry line to reduce scale buildup and improve water quality throughout the home.
Test your water before selecting a POE system so the treatment matches your specific contaminants.
“Test your water before selecting a POE system so the treatment matches your specific contaminants.”
POE systems protect appliances like water heaters and dishwashers by reducing scale and corrosion.
Do I need a POE system if I already have a sink filter?
A POU filter only treats one outlet; POE treats all water entering the home.
How often do POE filters need replacement?
It depends on water quality and usage, but most require periodic changes every few months.
Will a POE system lower water pressure?
If properly sized, pressure loss is minimal. Undersized systems can restrict flow.
