Excalibur Filtermax® Superior Chemical Removal Filter with catalytic activated carbon — a full cubic foot of catalytic carbon that removes most chloramines, chlorine and chemicals from every tap.

Most municipal water in KW, Cambridge and Guelph is treated with chloramine. This whole-house filter holds a full cubic foot of catalytic activated carbon — more effective than standard GAC — that removes most chloramines, plus chlorine, THMs, VOCs, and helps reduce PFAS and heavy metals, from every tap in the home. It's a simple in/out upflow design: no backwash, no salt, no chemicals, no cartridges, and the media lasts 10+ years.

KW, Cambridge & Guelph municipal water is largely chloramine — this is the thorough fix.
In/out upflow, no backwash, no salt; media lasts 10+ years.
Add it to a Value or Superior softener for soft, chemical-free water.
Standard granular activated carbon (GAC) is great at chlorine, tastes and odours — but it's poor at chloramine, the longer-lasting disinfectant most Kitchener, Waterloo, Cambridge and Guelph municipalities now use. Catalytic activated carbon is specially heat-treated to boost the carbon's catalytic activity, so it actively breaks chloramine down instead of just trapping it — removing far more chloramine (and hydrogen-sulfide "rotten-egg" odour) than ordinary GAC. That's why this filter uses a full cubic foot of catalytic activated carbon in an upflow, in/out design: water flows up through the bed for maximum contact time, with no backwashing, drain, salt or power.
Chlor-A-Soft softens water and removes most chlorine in one unit, but its small carbon bed doesn't remove much chloramine. This filter is a full cubic foot of catalytic activated carbon (more effective than standard GAC) dedicated to removing most chloramine (plus chlorine, THMs, VOCs, PFAS and heavy metals). Since most KW municipal water is chloramine-treated, it's the thorough choice — and it pairs with any softener.
No. It's an in/out upflow filter — no backwash, no drain, no salt, no electricity and no cartridges to change. The full cubic foot of catalytic activated carbon simply lasts 10+ years before the media is refreshed.

City water across Kitchener-Waterloo, Cambridge and Guelph is largely disinfected with chloramine — and ordinary carbon struggles with it. The Excalibur Filtermax® Superior Chemical Removal Filter with catalytic activated carbon holds a full cubic foot of catalytic activated carbon — heat-treated to actively break chloramine down rather than just adsorb it, so it removes far more chloramine than standard granular activated carbon (GAC) — clearing most chloramine along with chlorine, THMs, VOCs, PFAS and reduced heavy metals, so every tap in the house runs cleaner, better-tasting water. It's a simple upflow, in/out design — water flows up through the carbon bed for maximum contact, with no backwash, no salt, no chemicals, no electricity and no cartridges — and the media lasts 10+ years, backed by a 5-year warranty. It pairs with any softener (a softener removes hardness; this removes chemicals), and is delivered from $700 + tax, with professional installation available (+$145, including a 1-year labour warranty).
