Adey MagnaClean Atom Magnetic Filter & Chemical Pack 22mm review
Homeowners whose boiler is due a magnetic filter, especially where pipework space is tight.
By Tom Calder
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.

We may earn a commission when you buy, or a fee when you request a quote, through our links — it never affects what we recommend.

- 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
- Unit price doesn't include the heating engineer's labour to fit it on a sealed system
Who shouldn't buy this
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.
