Water filtration covers a wide range, from a $30 pitcher filter to a $5,000 multi-stage whole-home system. The right answer depends on what's in your water and what you want from it.
Most Kanata homes on municipal water don't need extensive treatment — Ottawa's municipal water is genuinely good. The most common installs are chlorine-reduction carbon filtration for taste, sometimes a sediment filter if internal piping is shedding rust or scale, and an RO unit at the kitchen sink for drinking water that's as clean as bottled without the bottles.
Rural Kanata, Carp, and Stittsville on private wells often need more comprehensive treatment — sediment, iron/manganese, UV disinfection, and softening. We design for what your water actually is.
Common signs you need this service
- Chlorine taste or smell at the taps
- Sediment or rust particles in the water
- Slight discoloration or yellow tint
- You're on a well and want comprehensive treatment
- Sensitive skin, eczema, or allergies in the household
- You currently use bottled water and want to stop
Testing first
Recommending filtration without testing is like prescribing without examining. We bring a portable test kit to every assessment and check the basics: hardness (mg/L as CaCO3), chlorine residual, total dissolved solids, pH, iron, and visible sediment. For wells, we also recommend a full lab test for bacteria, nitrates, and trace metals. The test takes 20 minutes and tells us — and you — what we're actually treating.
Sediment, carbon, and UV: the building blocks
A sediment filter (typically 5-micron pleated) removes particles — rust flakes from older piping, fine sand from a well, anything visible. A carbon filter (granular activated carbon or carbon block) removes chlorine, chloramines, organic compounds, and odors — the chlorine taste in municipal water disappears within a day of installing a carbon stage. UV disinfection uses a UV-C lamp to inactivate bacteria and viruses — essential for any well system, optional for municipal. These three stages cover 90% of residential filtration needs.
Reverse osmosis for drinking water
Reverse osmosis (RO) is a membrane filtration that removes virtually everything from water — dissolved solids, salts, heavy metals, fluoride, residual pharmaceuticals. The output is essentially distilled-grade water. RO systems are typically installed under the kitchen sink with a dedicated faucet — you don't typically run RO water to every tap because the production rate is too low (typical RO unit makes 50-75 gallons per day, with a small storage tank to buffer demand). A remineralization stage at the end adds back some calcium and magnesium for taste. RO is the gold standard for drinking water and is what most Kanata customers who used to buy bottled water install instead.
Whole-home vs point-of-use
Whole-home (point-of-entry) filtration treats every drop of water entering your home — cooking, bathing, laundry, drinking. Point-of-use treats just one tap (usually the kitchen). The right choice depends on what you're treating: if it's chlorine taste, whole-home makes sense because chlorine evaporates in hot showers and affects how laundry smells. If it's drinking-water purity, point-of-use RO at the kitchen is more economical than whole-home RO.
Maintenance reality
Every filtration system needs maintenance. Sediment and carbon cartridges typically last 6-12 months depending on water quality and usage. UV bulbs need annual replacement. RO membranes last 2-5 years. We schedule maintenance with you and remind you when it's due — a forgotten filter change means you're drinking water through saturated media, which is worse than no filter at all.
Our process
- 1
Test your water
We test for hardness, chlorine, iron, sediment, pH, and TDS to know what you're actually treating.
- 2
Design the right system
Sediment + carbon for municipal water; sediment + iron/manganese + UV for most wells; reverse osmosis at the kitchen tap if you want bottled-quality drinking water.
- 3
Install at the main
Whole-home filtration installs on the cold supply right after the meter (or after the pressure tank for wells).
- 4
Commission and instruct
We start up the system, verify flow and pressure, and walk you through filter change intervals and any maintenance routine.
What's included
- On-site water testing
- System design and sizing
- Installation at the main supply
- By-pass loop for service
- Pressure and flow verification
- Owner walkthrough and maintenance schedule
What affects the price
System complexity
Sediment + carbon: simplest. Add iron/manganese, UV, RO, and the system grows.
Plumbing access
Most Kanata mechanical rooms have plenty of space. Tight or partially finished spaces may require some plumbing rework.
Tankless RO vs traditional RO
Traditional RO with a small storage tank is most common. Tankless RO is a newer option with better flow but higher cost.
Why Kanata homeowners choose us
- We test before we recommend — no one-size-fits-all package sales
- We install with a by-pass loop so future filter changes don't require shutting off your whole house
- We service what we sell — annual filter changes and UV bulb replacements are scheduled with you
- Honest assessment when filtration isn't needed — Kanata municipal water is genuinely good
Kanata is on the City of Ottawa municipal water system, sourced from the Ottawa River, treated at the Britannia and Lemieux Island plants. The water is genuinely good — meeting all Health Canada guidelines and tasting better than many cities. Most Kanata filtration installs are for: chlorine taste reduction, sediment removal from older internal piping, or drinking-water polishing via RO at the kitchen. Rural Kanata, Carp, and Stittsville on wells often have more complex treatment needs.
Materials & brands we trust
- 3M Aqua-Pure
Our preferred whole-home cartridge filtration.
- Viqua UV disinfection
Canadian-made UV systems for well water disinfection.
- iSpring RCC7AK reverse osmosis
Excellent value RO with remineralization for drinking-water installs.
All installs include a by-pass loop per OBC and best practice. Backflow prevention is verified. UV systems include flow controls to ensure adequate UV dose at maximum flow. RO drain lines include code-compliant air gaps.
Filter cartridge replacements (on existing systems) are designed for homeowner maintenance. Installing a new whole-home filtration system involves cutting into your main supply, which is a poor DIY target unless you're already comfortable with plumbing — a mistake here affects every fixture in your house.
