"a magnetic filter is a device that collects magnetic debris within a heating system. Rust and corrosion can form in pipes over time, and the subsequent debris will peel off and combine with other debris to form a sludge-like substance
Having a magnetic filter that's regularly maintained will benefit you with long-term savings on energy bills, reduced repair costs and an extended lifespan on your boiler

I don’t actually know of any disadvantages of having one. Defo worth the money. Long term"

"Pro - they can extend a boiler warranty.. they also protect the boiler from magnetite which can cause the boiler heat exchangers and radiators to get blocked...

Con - space can sometimes be an issue installing one.. people never bother getting them cleaned on a yearly service.. certain ones can leak after a few years..."

"It’s always a thing to have with your boiler. It keeps your boiler healthy keeps all the debris that comes from your heating system entering the boiler. But you need to have it cleaned every time you have your boiler serviced."
