Compatibility
Check boiler and filter instructions, pipe arrangement, available space and the intended flow direction.
System protection
Do I need a magnetic filter on my boiler?
A magnetic filter can capture some circulating magnetic debris, but whether one is required or suitable depends on the appliance, system design, existing protection and manufacturer guidance.
What to consider
Installation and servicing
Correct installation, isolation, cleaning and ongoing maintenance matter; a neglected filter cannot provide its intended function.
Whole-system condition
A filter does not correct every corrosion, water-quality, circulation or component problem and is not a substitute for investigation.

Do not fit, remove or service heating components unless competent and authorised to do so. Follow the appliance manufacturer and a suitably qualified professional.
