Welcome to Johnson Magnetic Filters we design and manufacture what we feel are the most reliable, smart and better performing central heating magnetic filters on the market. They are "simply the best."
What makes our products so unique is the fact that we use the best plumbing materials namely copper, brass and stainless steel (no plastic). Our filters are able to provide higher temperature and pressure performance results which in turn produces a more premium product with the best reliability and longevity.
We have also chosen to combine standard magnetic debris capture alongside a self-cleaning stainless steel mesh, in order to provide outstanding magnetic and non-magnetic particulate separation and therefore ultimate boiler protection.
These images clearly show how smart the Pro-Series filters really are. They can be easily dosed with lower costing liquids, and will filter 100% of all non-magnetic debris above 3mm. Performance wise they will take a much higher pressure and temperature than any plastic filter!
Our unique in-line and protected designs demonstrate how compact and practical the Pro-Series filters really are. Most plastic filters tend to look more bulky, less easy on the eye and have a tendency to twist and rotate. Don't you just love finding and then pulling on the big plastic spanner and watching the plastic body flex in disbelief, when it just won't open!
As you can see the Pro-Series filter takes up much less space they are reliable, quick and easy to fit and clean. Our filters are very strong and rigid and do not require extra pipe clips for support unlike other flexible filters. All of our filters are handcrafted, made in Great Britain and are supplied with a 25 year warranty!
