Navien Tankless Water Heaters 30010677A Water Inlet Filter

The Navien 30010677A Water Inlet Filter is a replacement filtration component designed for use in compatible Navien tankless water heaters and combi boiler systems. It works by filtering sediment, debris, and other contaminants from the incoming water supply before it enters the heat exchanger and internal components. This helps maintain proper water flow and protects the system from buildup that can affect performance. Ideal for routine maintenance, the filter supports reliable operation, improves efficiency, reduces wear on critical components, extends equipment life, and helps ensure consistent hot water delivery.
