Household water is increasingly contaminated with PFAS "forever chemicals," microplastics, pharmaceuticals, insecticides, and pesticides — contaminants that standard water treatment doesn't fully remove. The Excalibur Whole Home Reverse Osmosis System removes up to 99% of these dangerous contaminants, delivering safe, clean, high-purity water to every tap, every shower, and every appliance in your home.

Unlike under-sink reverse osmosis systems that only treat your kitchen tap, this system purifies your entire water supply — so you're not just drinking clean water, you're bathing in it, cooking with it, and washing your clothes in it.

Why Whole Home RO?

  • PFAS "forever chemicals" are found in municipal water supplies across Ontario and cannot be removed by standard treatment
  • Microplastics are present in virtually all tap water and pass through conventional filtration
  • Pharmaceuticals, insecticides, and pesticides are increasingly detected in both municipal and well water sources
  • A standard water softener removes hardness but does NOT remove these contaminants
  • An under-sink RO treats only your kitchen tap — this system treats your entire home

Six Steps to High-Purity Water

1
Custom pre-filtration

Custom Pre-Filtration

Based on your water analysis, additional filtration is used as pretreatment to protect the high-purity TFC (Thin Film Composite) reverse osmosis membranes, extending their life and performance.

2
Water softener

Water Softener

Based on your water analysis, a water softener removes water hardness (calcium and magnesium) that would otherwise damage and reduce the lifespan of the reverse osmosis membranes.

3
Commercial-grade RO system

Commercial-Grade Reverse Osmosis System

The heart of the system. A commercial-grade RO unit removes chemicals, heavy metals, organics, microplastics, PFAS, pharmaceuticals, and other contaminants — reducing total dissolved solids (TDS) to produce high-purity water.

4
Holding tank

Holding Tank

Purified water is stored in a pressurized holding tank, ensuring a ready supply of high-purity water is always available for your household on demand.

5
Repressurization pump

Repressurization Pump

A high-quality DAB pump delivers high-purity water from the holding tank to your household at full pressure — so you never notice a difference in water flow at any tap or appliance.

6
pH neutralizing filter

pH Neutralizing Filter

A pH-balanced neutralizing filter is the final step after the reverse osmosis system, ensuring your purified water is pH-balanced and non-corrosive to your home's plumbing.

Applications

  • Municipal water homes concerned about PFAS, microplastics, and chemical contamination
  • Well water properties requiring comprehensive purification
  • Well water with high chloride (salty taste or elevated sodium/chloride)
  • Lake and cottage water treatment
  • Families with health-sensitive members (infants, elderly, immunocompromised)
  • Homeowners who want the purest possible water from every tap

What's Removed

  • PFAS (forever chemicals) — up to 99%
  • Microplastics — up to 99%
  • Pharmaceuticals and drug residues
  • Insecticides and pesticides
  • Heavy metals (lead, arsenic, mercury, cadmium)
  • Chlorine and chloramine byproducts
  • Dissolved chlorides (e.g. sodium chloride in well water)
  • Volatile organic compounds (VOCs)
  • Total dissolved solids (TDS)
  • Bacteria and viruses (with pre-UV where needed)
  • Nitrates and nitrites

High chloride in well water?

Many well water supplies have elevated dissolved chlorides — often from natural geology or road salt — which can cause a salty taste, accelerate corrosion, and damage appliances. A water softener does not remove chloride; it exchanges hardness minerals for sodium, so chloride levels stay the same or increase. In this setup, the reverse osmosis stage removes dissolved chlorides (and other dissolved solids) by pushing water through a semi-permeable membrane, so the purified water delivered to your taps is low in chloride and other TDS.
