Keston 22mm System Filter is a magnetic filter designed to protect domestic central heating systems against the damaging effects of contaminants, sludge or debris.
This filter has been specifically crafted for use with Keston Combi and System boilers, extending the warranty of both boilers from 5 to 7 years† as it improves overall efficiency of the heating system. In turn, installing a system filter also reduces boiler running costs.
Keston 22mm System Filter works by ensuring any build-up of sludge or debris does not block your heating system and cause damage to the boiler. The filter attracts contaminants and removes them from the system, ensuring only clean water is circulated back to the boiler.
