Our verdict · Researched
4.3 / 5

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
Homeowners whose boiler is due a magnetic filter, especially where pipework space is tight.
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

ⓘ As an Amazon Associate, PreparedBritain earns from qualifying purchases. We may earn a commission when you buy, or a fee when you request a quote, through our links. When two products are close, commission can decide which one we pick. A clearly better product always wins. Amazon prices come from Amazon's own product data and show the date and time they were retrieved. Prices at other retailers are checked by us, less often. Prices and stock can change at any time, so always check the retailer's price before you buy.

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.

How this review works

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.
