The performance and longevity of your tankless water heater, small components can make a big difference. One such unsung hero is the inlet filter—a simple but essential part that helps keep your water heater running efficiently by filtering out debris and sediment before they can cause damage. Among the most reliable and compatible options on the market is the EGBD032 Inlet Filter, specially designed to fit Noritz tankless water heaters.
This compact component sits at the water inlet and plays a critical role: it filters incoming water to trap particles, sediment, sand, and other contaminants that can build up inside the heater and reduce its efficiency or cause long-term damage.
Made from durable materials and engineered to meet OEM specifications, offers a reliable, snug fit and consistent filtration performance. It’s easy to install, compatible with a wide range of Noritz models, and provides an affordable way to protect one of the most valuable systems in your home.
Unlike traditional water heaters that store hot water in large tanks, tankless water heaters heat water on demand as it flows through the system. This makes them highly efficient and compact, but it also means they’re more sensitive to water quality. Sediment or debris entering the system can clog internal passages, damage heating elements, or reduce heat transfer—leading to higher energy bills, poor performance, or expensive repairs.
Key Benefits of an Inlet Filter:
-
Prevents buildup of dirt, rust, or minerals inside the heater
-
Reduces the risk of clogs and overheating
-
Improves efficiency and water flow
-
Extends the life of your tankless unit
-
Protects downstream components like flow sensors and heat exchangers
In short, it acts as the first line of defense in your water heating system.
One of the top concerns when purchasing a replacement filter is whether it will properly fit your specific model. Engineered to be compatible with Noritz tankless water heater models, making it a hassle-free replacement option for your existing inlet screen assembly.
It is designed to match the specifications of the original OEM part, so installation is straightforward and performance is dependable. If your current Noritz system uses a threaded or screen-style inlet filter, chances are the EGBD032 is a suitable fit.
✅ Tip: Always refer to your user manual or contact your manufacturer to confirm model compatibility before purchasing a replacement part.
