Adey MagnaClean Professional 3 Sense Magnetic Filter 22mm — FL1-03-03434 review
Homeowners, landlords or installers who want proactive Wi-Fi alerts on heating system health, not just passive filtration

Adey is the UK's leading magnetic filter brand, and the Pro3 Sense adds genuine remote monitoring on top of its proven filtration — useful if you want an early warning before a breakdown. Fitting is a job for a competent DIYer or heating engineer on a sealed system, and the inhibitor should be topped up afterwards per BS 7593:2019.
