Water Purification for Windsor & Essex County
Water quality in Windsor, Ontario is more complicated than most people realize — and a single solution rarely fits every home. Whether your water comes from the municipal supply fed by Lake St. Clair, a private well in rural Essex County, or aging pipes in an established neighbourhood near Tecumseh Road, what ends up at your tap carries its own set of challenges. Hard minerals, iron, agricultural runoff contaminants, PFAS compounds — the list depends on where you live and how the water gets to you. Aerus of Windsor has been solving these problems for Windsor-area families since 2006, and the first step is always the same: knowing exactly what's in your water.
Start With a Free Water Test
Before we recommend anything, we test. Our free in-home water test is the foundation of every project we take on. A technician comes to your home, tests your water on-site, and walks you through the results in plain language. No pressure, no guesswork.
The results shape everything: which system makes sense, where it should be installed, and what maintenance schedule to follow. We don't sell from a catalogue. We prescribe based on what your water actually contains.
Water Softeners and Conditioners
Hard water is the most common water quality complaint in Windsor-Essex. It leaves scale on fixtures, reduces soap lather, shortens the life of water heaters and appliances, and leaves that filmy residue on dishes and glassware. Windsor's municipal water draws from the Great Lakes and carries measurable hardness. Well water in parts of Essex County runs harder still.
We supply traditional ion-exchange water softeners and the Aerus Origins line of salt-free water conditioners — the WC400, WC300, WC200, WC150, and WC100 — sized for homes of every volume. The right choice depends on your water chemistry, household size, and whether you prefer salt-based or salt-free treatment.

Whole Home Water Filtration
A whole home water filter intercepts contaminants at the point water enters your home. Everything downstream — showers, dishwashers, ice makers, laundry — benefits from cleaner water. This matters more than people often expect: chlorine and chloramine in municipal water don't just affect taste. They affect skin, hair, and the lifespan of rubber seals and appliances.
We carry the Aerus F100, F100V, and F150V whole home filtration systems, each designed for different water profiles and household sizes. Our whole home filtration page covers the options and what each system addresses.
Iron and Contaminant Treatment
Iron staining in sinks and tubs — that orange or reddish-brown ring — is one of the most common complaints we hear from well-water homeowners in Essex County. Manganese often accompanies iron and shows as a darker, greyish stain. Beyond iron, some properties deal with arsenic, tannins, hydrogen sulphide, or elevated acidity that requires targeted treatment.
We carry the Aerus ISM200 for iron, hydrogen sulphide, and manganese removal, the AR100 for arsenic, the C150 for acidity correction, and the T150 for tannin removal. Each unit addresses a specific set of contaminants, and what you need depends on what your test results show. Details are on the iron and contaminant treatment page.
Reverse Osmosis Systems
Reverse osmosis is the most effective technology available for drinking water purification. It forces water through a semi-permeable membrane that removes dissolved solids, heavy metals, chlorine byproducts, nitrates, PFAS, and a wide range of contaminants down to the sub-micron level.
Our Elevate pH 600+ reverse osmosis system uses six treatment stages — including four stages of advanced filtration — and reintroduces minerals to elevate pH after the purification process. It installs beneath the kitchen sink and connects to a dedicated faucet. For well water with multiple contaminants, RO is almost always part of the solution. For municipal water, it removes everything that survived the treatment plant.
Learn more on the reverse osmosis page.
PFAS and Forever Chemical Treatment
PFAS (per- and polyfluoroalkyl substances) — sometimes called forever chemicals — have been detected in water sources across Ontario and throughout the Great Lakes basin. Agricultural activity in Windsor-Essex, combined with legacy industrial use in the region, means this is a legitimate concern for local residents.
High-performance activated carbon filtration and reverse osmosis membranes are the most effective residential approaches for reducing PFAS and PFOS compounds. If your water has been tested and flagged for these contaminants, or if you're on well water near agricultural land and haven't tested, this is worth understanding.
We stay current on Health Canada guidelines and the evolving science around PFAS limits. We'll give you a straight answer about what level of treatment your situation calls for.
Well Water Filtration for Rural Essex County
Homes in Kingsville, Leamington, Amherstburg, and Essex often rely on private wells. Unlike municipal water, well water isn't tested or treated at a central facility. What you draw is what you get — and that changes with the seasons, with nearby land use, and with the age and condition of your well casing.
Agricultural runoff carrying nitrates and bacteria is a documented concern in this region. We test well water thoroughly and design filtration systems that address the full chemistry — not just one or two parameters. Our Essex County service page covers the county-wide picture in more detail.
Replacement Filters and Cartridges
A filtration system is only as good as its maintenance. We supply replacement filters and cartridges for the systems we install and service, and we keep records of your system so we can reach out before a change is overdue.
If you have an existing system from another supplier and want us to take over servicing, contact us and we'll assess what's installed and what it needs.
