  • Filters
  • Chemicals


  • Is there a recommended schedule for adding or "topping up" inhibitor levels?

    Inhibitor levels should be tested annually and topped up if necessary.

  • Why does black sludge develop inside hydronic heating systems?

    Iron oxide, or magnetite, is a result of natural oxidation inside nearly all untreated iron pipe systems. Any structure built before 1960 is likely to have iron pipe, and it's still used today. Fine particles of iron oxide eventually build up to form black sludge.

  • Does my MagnaClean come with a warranty?

    Yes — a two-year warranty is standard with every MagnaClean filter.

  • How long has the product been available in the US?

    Official North American rollout began in October 2016. But MagnaClean has been available in Europe for over 10 years, with over 4,000,000 units installed.

  • How can I buy this product if I live in Canada

    Absolutely! Email or call (844)378-0442 for contact information on how to order from Canada.

  • What's the word on the street about MagnaClean? Are people talking about it?

    Yes! Overheard at AHR Expo, 2017… “You are the first company I know of that does this.” “I've been looking for something new all over this show. Looks like I've found it!” “Wow...that works fast.” “It's hard to believe it's so simple, yet it works so well.” “I don't know why every hydronic heating installation doesn't have a MagnaClean filter on it.” (...Neither do we.)

  • When using MagnaClean, how do you keep the loosened magnetite from flowing back into system?

    It stays attached to the magnetic rods until you remove them to rinse, and will not get pulled back into system water.

  • Are there other solutions for removing iron oxide?

    Yes, but none that work this well to remove iron oxide. There are mesh strainers and basket filters, both of which can clog or reduce the flow inside a system. Also, because individual particles of magnetite are .0003 microns in size, they are too small to be caught by the holes in mesh strainers. It would be like trying to catch a football in a net with holes the size of the Statue of Liberty. MagnaClean captures iron oxide particles completely independently of particle size.

  • What is MagnaClean the retrofit process?

    For residential applications, it is a simple process. You simply cut a 6-inch section of pipe out, and then fix the compression fittings to those pipes and tighten the valves.

  • Is MagnaClean for retrofit applications or new construction

    Both. Whether you're retrofitting or installing in new construction, the process is quick and simple.

  • What is the range of applications for MagnaClean covers?

    There is a MagnaClean for nearly every installation. There are models for everything from small residential, residential, light commercial, up to large industrial.

  • How long do the magnets last? How long do they keep their strength?

    Our filters test on a 12-year life cycle, and we will soon be offering a 10-year warranty on our magnets. We have seen filters installed for longer than that, and they are still working effectively.

  • Are there any moving parts?

    No — MagnaClean works as water flows around the magnet. It is directed in a cyclonic flow around the inside of the canister due to the design of the inlet and outlet valve, maximizing first-pass capture without the need for moving parts.

  • How do I remove the sludge from the filter after it's collected?

    You simply remove the magnetic rod and sheath. Once the sheath is removed, the magnetite simply falls off. You can rinse off any residue very easily with running water.

  • Does MagnaClean just filter out iron oxide?

    Larger, non-magnetic debris such as flux and solder will also be filtered out in the top and bottom capture zones of residential filters, while magnetic debris will collect around the magnet in the canister.

  • Why are the valves labelled A & B?

    This is solely for our reference. Valve A is a slip collar.

  • Can the valves be fitted either way?


  • Can I install the filter horizontally?

    This is not recommended as it could cause air locks in the filter, it will be difficult to service and may cause flow restrictions. It will also have an impact on the collection of non-magnetic debris.

  • Can I fit a whole bottle (1.05 pints) into the canister?

    No, we would suggest doing half at a time (quarter of a bottle for a MagnaClean Micro2™).

  • Can either port be used as the inlet?

    Yes, the filter is bi-directional.

  • How many radiators will MagnaClean Micro2 clean?

    A MagnaClean Micro2 will sufficiently maintain a clean system on up to 15 radiators.

  • How frequently do I need to clean the filter?

    We recommend it is cleaned once a year, using the ADEY Best Practice five-step process.

  • Will the filter capture none-magnetic debris?

    Yes, as long as it is installed in accordance to our instructions.

  • Are chemicals needed?

    Yes, they are recommended as part of ADEY's Best Practice™ System - Use MC3+ Cleaner before installing MagnaClean to loosen existing debris, sludge, lime scale deposits and system corrosion. Use MC1+ Inhibitor after installation to protect against further system corrosion.

  • What is the difference between RAPIDE and regular System Treatment Formulas?

    Same formulas, different dosing methods. RAPIDE can be dosed in just 20 seconds into the radiator using the attached rapid-dose nozzle, while regular chemicals are poured into the MagnaClean canister.

  • How do you determine the dilution of the cleanser?

    One bottle handles up to 15 radiators. If you're dosing a larger system, you'll need more (e.g., 2 bottles for up to 30 radiators).

  • What is MC3+?

    MC3+ is our system cleaner specially designed to remove hydronic heating system sludge and debris. Use as part of the ADEY 5-step Best Practice Process

  • How long can I leave MC3+ in the system?

    From 1 hour up to a maximum of 28 days. As part of our best practice we recommend leaving it in for as long as possible (not exceeding 28 days).

  • What is MC1+?

    MC1+ protects against both system corrosion and limescale deposit buildup.

  • How do you put MC+3 RAPIDE and MC1+ RAPIDE into the system?

    These can either be put in via the air vent on your filter or your radiator as they are in pressurized canisters.
