The IX Defend is the heavy-duty option in the IX range, built with advanced multi-stage filtration to protect water systems and equipment from scale, gypsum and corrosion — the three problems that show up hardest in genuinely difficult water conditions. By balancing mineral content, reducing hardness-forming calcium and maintaining a stable pH, it's designed to safeguard equipment from boilers to steam ovens against damaging deposits and corrosion, even in challenging water conditions.
It's built on the same reusable IX Variable Head and casing as the rest of the range, with the internal cartridge exchanged and regenerated once it reaches capacity rather than the whole unit being replaced. A 5-stage filtration process (prefiltration, activated carbon, targeted hardness reduction, media-specific treatment and fine filtration) is where PFAS reduction also takes place, alongside the scale, gypsum and corrosion protection.

Who it's for
Sites in particularly hard, mineral-heavy or corrosive water areas — larger catering operations, multi-appliance kitchens, or any site that's had repeat scale, gypsum or corrosion-related equipment failures other filters haven't solved.
Why buy this from WrekinWater
We can test or discuss your local water hardness and mineral profile to confirm IX Defend is proportionate to your conditions, rather than over- or under-specifying protection.
