Brita Longlast Water Filter vs Noritz NRCB Combi Boiler

The Brita Longlast Water Filter is a high-capacity replacement cartridge designed for Brita pitchers and dispensers. It provides up to six months of filtration, removing lead, chlorine, and other contaminants while preserving essential minerals for better taste. Ideal for households and offices, the Longlast filter offers a cost-effective solution to reduce bottled‑water waste and improve hydration quality without the need for electricity or complex installation.

The NRCB series is Noritz's combination boiler, which handles both space heating and domestic hot water from a single wall-mounted appliance. That combination is the point: instead of a boiler for the radiators and a separate tank water heater, one unit does both, freeing the floor space a tank would occupy and removing the standby heat loss that comes with keeping a tank hot around the clock. Because it is tankless on the hot water side, supply is continuous rather than limited by tank capacity, so back-to-back showers do not run out. Noritz is a tankless water heating specialist with residential and commercial ranges, and supports the NRCB with a sizing guide, plumbing diagrams, BIM and Revit files, installer training, a PROCard programme and installer and servicer locators.
