The Navien 30007878A is a DHW cold water inlet filter (also called a water inlet filter or cold water filter) for Navien condensing gas combination boilers and tankless water heaters. It filters the cold water supply before the water enters the unit.

• Catches debris and sediment before it reaches the heater

Checking the inlet filter and replacing it when needed helps keep water flowing normally and protects the internal components of the heater.
