Welcome to Johnson Magnetic Filters - Specialists in Central Heating Protection

The Johnson Pipefilter Pro-Series range are the smartest and most reliable high performance heating system filters on the market. They are perfectly designed for installations where space is at a minimum, or the customer simply prefers the smarter appearance and excellent reliability. They protect and increase the energy efficiency of a domestic central heating system by capturing and removing the circulating steel dirt ie. black sludge (magnetite). 

The simple non plastic design has been chosen to provide the best long term performance, whilst providing the customer and installer with ultimate reliability, longevity, maximum peace of mind and brilliant value for money. Copper and brass are renowned to be the finest and most trusted plumbing materials, no compromise has been made with our choice of materials and build quality. 

Our magnets feature a large surface area and therefore provide high performance sludge removal. They are a more slimline alternative to jar derived filters, and are the perfect solution for installations in confined spaces and restriced areas. For greater flow rates several filters can be coupled together in a paralell combination to form a fork shape to divide the flow.
