Worcester Greenstar 28mm System Filter
The Worcester Greenstar 28mm System Filter is designed to safeguard your heating system by capturing debris, sludge, and other pollutants that naturally build up over time. By preventing these contaminants from circulating through your boiler or heat pump, the filter helps maintain efficiency, reduces the risk of component wear, and can save you money on costly repairs down the line.
Thanks to its powerful internal magnet, this filter is highly effective at trapping magnetic debris, ensuring your system stays cleaner for longer. It’s a simple but essential addition that promotes reliable, long-term performance — especially for larger heating systems with 28mm pipework.
