Worcester Greenstar System Filter 22mm

Worcester Greenstar 22mm System Filter

The Worcester Greenstar System Filter 22mm helps protect a central heating system by reducing debris, sludge and magnetic particles that can affect performance over time. It is a sensible addition when upgrading key boiler parts during a service, repair or new installation. Within our boiler accessories selection, this product supports cleaner water circulation and better system care.

The Worcester Greenstar 22mm System Filter is designed to protect your heating system from the build-up of debris, sludge, and unwanted pollutants that naturally collect over time. By capturing these contaminants before they circulate through your boiler or heat pump, the filter helps maintain efficiency and reduces the risk of breakdowns - ultimately saving homeowners money on repairs and extending the life of their system. Built with a high-powered internal magnet, the filter is capable of trapping large amounts of magnetic debris, ensuring your system stays cleaner and runs more smoothly. It's a simple but highly effective way to keep your heating performing at its best all year round.
