Worcester Greenstar 22 mm Mini System Filter

The Worcester Greenstar 22mm Mini System Filter has been designed to combat the damaging effects of system debris and pollutants, allowing homeowners to protect their boiler or heat pump for a fraction of its cost.

The new Mini System Filter offers the same features as the rest of Worcesters filter range but in a more compact size.

The filters have a high powered internal magnet that can capture large amounts of magnetic debris.
