Adey MagnaClean Atom Magnetic Filter & Chemical Pack 22mm
By Tom Calder
We no longer recommend this model, so it no longer appears in our buying guides. In its place, we now recommend Adey MagnaClean Professional2 Filter & Chemical Pack 22mm — CP10300625 in our Radiator & heating efficiency guide.
Key specs
The maker's figures.
- What it is
- Magnetic filter plus chemical pack for sealed
- How it works
- In-line magnet strips black iron oxide sludge
- Fits

A compact, well-regarded filter from the UK's market-leading brand, bundled with the cleaner and inhibitor dose needed to do the job properly. Fitting is a job for a qualified heating engineer, so budget for labour on top of the unit price.
- Best for

- Skip it if
- Your system already has a working magnetic filter

Researched, not used. We haven't used this product. This review is built from the maker's specifications, owner reports and our own sizing.
What we like
- Compact 115mm footprint suits tight pipework where a standard filter won't fit
- Bundle includes MC3+ cleaner and MC1+ inhibitor for a full system dose (systems up to 125 litres)
- Bypass valve lets the filter be cleaned without draining the whole system
- 10-year warranty if registered within 30 days of install
Worth knowing
- Unit price doesn't include the heating engineer's labour to fit it on a sealed system

Who shouldn't buy this
Don't buy it if your system already has a working magnetic filter — in that case you just need an inhibitor top-up (BS 7593:2019 recommends one after any system work), not a whole new unit.
This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the UK price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.
