Water Softeners & Filtration Systems for Ottawa Homes
The full Honest Water Co. line-up, from whole home softening to tankless reverse osmosis. The right system depends on your home and your water, and the consultation is free.
If you're on City of Ottawa water, your water is already very soft — the City reports around 30 mg/L (about 2.5 grains per gallon). You don't need a water softener. What city homes actually need is chlorine and chloramine treatment, better taste, and clean drinking water.
Built for Ottawa city water — no salt, no brine tank
Ottawa City Water Package: Whole-Home Chloramine Filter + Reverse Osmosis
Our flagship package for homes on Ottawa city water: a whole-home catalytic carbon tank that reduces chloramine taste and smell at every tap, shower and appliance, paired with the HW800 AlkaPro 7-stage tankless reverse osmosis system and its own faucet at the kitchen sink. Ottawa's water is already soft, so there is no softener, no salt and no brine tank to look after.
Salt-free carbon filtration, no electricity, no drain
Carbon Only Water Filter
Whole Home Carbon Filter

Tankless Reverse Osmosis
HW800 AlkaPro
The HW800 AlkaPro is a smart, tankless reverse osmosis system that fits under the kitchen sink and makes clean water on demand — no storage tank, no waiting, no bottled water. Its 7-stage high-precision filtration uses an ultra-fine 0.0001 micron (μm) membrane to reduce heavy metals, dissolved solids, chlorine, microplastics, PFAS and other everyday contaminants, while a natural coconut carbon block and built-in alkaline remineraliser bring the taste and minerals back.
What it does
7-stage filtration down to 0.0001 micron (μm)
Reduces heavy metals, dissolved solids, chlorine, microplastics and PFAS
Built-in alkaline remineraliser balances pH and improves taste
Efficient 2:1 low drain ratio — far less wastewater than standard RO
Auto RO flush keeps the membrane clean and extends its life
Tankless design saves up to 70% of under-sink space
Stages 2–3: double NSF carbon block filters for chloramine, THMs and TCE
Stage 4: NSF thin film composite RO membrane, 95–99% rejection, 800 Gallons Per Day
Stage 5: in-line NSF coconut shell GAC filter for taste and odour
Stage 6: internal alkaline remineraliser to balance pH
Stage 7: second in-line NSF coconut shell GAC polishing filter

Stores purified water, ready at the faucet
Reverse Osmosis Tank
The Reverse Osmosis Tank stores purified water from your reverse osmosis system and keeps it pressurized, so clean water is ready the moment you open the faucet. Built with a high-strength steel shell and a food-grade butyl bladder, its compact footprint tucks neatly under most kitchen sinks.
What it does
Stores purified water — a ready supply under your sink for drinking, cooking, coffee makers and fridge ice lines
Keeps pressure steady — the pre-pressurized design delivers consistent flow at the faucet every time you fill a glass
Keeps water fresh — a food-grade butyl bladder separates the water from the air chamber
On a private well, or a municipal well in Carp, Vars, Richmond, Munster or Greely? Your water is genuinely hard — 200 to 350 mg/L — and often carries iron or sulphur. This is where softening and filtration make a real difference.

How the system works
The Resin & Carbon Tank
The heart of the system. Thousands of tiny resin beads capture the hardness minerals that cause scale, dry skin and spotty dishes, while granular coconut shell carbon takes out the chlorine and chloramine taste in Ottawa city water. Softer water, better taste, one tank.
The Brine Tank
Every whole-home system includes a brine tank — the part that keeps your softener working at full strength, year after year. It holds the salt that automatically rinses the captured minerals away and recharges the system overnight while you sleep. The only thing you'll ever do is add salt when it runs low: no filters, no tools, no service calls.
The Tankless Reverse Osmosis Unit
Under the kitchen sink, the HW800 AlkaPro makes drinking water on demand through 7 stages of filtration down to 0.0001 micron, then puts the good minerals back. No storage tank, no waiting, no bottled water.
Hardness and chlorine handled in one tank
Whole Home Filtration System
Water Softener with Chlorine Filtration
Our flagship whole-home system tackles the two most common complaints in Ottawa homes at once: hardness and chlorine. It softens by removing calcium and magnesium while granular activated coconut shell carbon reduces the chlorine that causes flat-tasting water, pool-like odour and dry skin.
What it does
Removes hardness minerals that scale kettles, taps and water heaters
Reduces chlorine taste and odour from City of Ottawa water
Gentler on skin and hair, less soap and detergent needed
Protects plumbing, fixtures and appliances from scale
Free professional installation · Lifetime Warranties
What's Inside
What's inside your system — and what each part does.
Scale control without salt or chemicals
Whole Home Salt-Free Conditioner
A salt-free conditioner transforms hardness minerals so they are far less likely to stick to pipes, elements and glass, without stripping the natural minerals out of your water. No salt, no regeneration cycle and no wastewater.
Our whole-home ultraviolet water purifier uses UV light to neutralise bacteria and microorganisms, providing chemical-free protection for your entire home. Water is treated as it enters your system, delivering safe, purified water at every tap.
What it does
Chemical-free disinfection
Kills 99.9% of bacteria
Treats water as it enters the home, protecting every tap
Built for Ottawa-area well water with iron and hydrogen sulphide. A hydrogen peroxide injection panel oxidises iron and sulphur at the point of entry, a catalytic carbon tank captures what the oxidation releases, and a high-capacity softening tank removes hardness — so the staining, the smell and the scale are handled by one system.
What it does
Removes the rotten-egg smell caused by hydrogen sulphide
Stops rusty orange staining on fixtures, sinks and laundry
Softens hard water to protect appliances and plumbing
Treats every tap in the home at the point of entry
Injects hydrogen peroxide where water enters the home, breaking down iron and sulphur through oxidation so the carbon tank can capture and flush them away.
Hydrogen Peroxide Holding Tank
Stores the peroxide solution and feeds it steadily as you use water, keeping the oxidation process consistent day to day.
Catalytic Carbon Tank
Granular activated catalytic coconut shell carbon traps the oxidised iron and sulphur, then rinses itself clean during backwash.
Softening Resin Tank
10% crosslinked high-capacity resin removes hardness minerals, with polishing gravel underneath to prevent channelling and keep flow even.
Brine Tank
Holds the salt that recharges the softening resin automatically overnight. All you ever do is top up the salt.
Not sure which system you need?
That's normal, and it's why we assess first. We'll tell you honestly if you only need one stage instead of three.
