Review: Works well and simple to install and use - Good quality parts. Straightforward to fit and maintain with no leaks. The two isolation valves are easy to operate for cleaning out. Heavy particles collected by the filter can be emptied out first. Magnetic particles can be released by withdrawing the strong magnet. An impressive amount of crud was collected in a bucket after only a few days.
Review: Great Product _ Great Value - Really good product. I swapped out a a Fernox TF1 which is 3 times the price of this one. Same fittings, insert size and it was an easy fit/ replacement. A*

## Features

- Perfect filter: A remarkably versatile central heating filter made to address the issues brought on by magnetic system sludge.
- Defender for Heating system: The new Boiler-m8 magnetic system filters offer your heating system by combining high strength magnetic and stainless steel particle filtration
- Sludge Filtration: To preserve central heating systems in good condition and boost overall efficiency, Boiler-m8 central heating system filters remove sludge. This is accomplished by preventing the accumulation of sludge in radiators by the effective removal of system debris
- Water tight seal: Our special 2-Way 360-degree Brass diverter body connection includes dual telescopic seals that can be turned while under pressure for simple maintenance, and our full-flow isolating valves have flat-faced unions and high pressure ratings to assure a watertight guarantee.
- How it works: Our 2-way 360-degree diverter directs system water into the filter body. Due to the reduced water flow created by our filter design, both magnetic and non-magnetic debris can be removed from the system using the high strength EZY-Clean disposable magnet stack and particle filter.
