Who is illi Water, and where are they based?
Who is illi Water, and where are they based?
illi Water is a Canadian water filtration brand born from Watermart, a company that has been supplying clean water to Canadian families for over 30 years. We're an online-first brand built to make premium water purification more accessible, bringing certified, professional-grade systems directly to your door without the markup of a traditional retailer.
Why buy from illi Water instead of a big box store?
Why buy from illi Water instead of a big box store?
When you buy from illi Water, you're buying directly from the source, which means better pricing, expert guidance, and support that doesn't end at checkout. Every system comes with free shipping across Canada, a 90-day satisfaction guarantee, and a 1-year warranty. Big box stores can't connect you with a water expert or help you troubleshoot a filter replacement over email.

What makes illi Water different from other water filter brands selling online?
Three things set us apart: heritage, transparency, and service. Our systems are built on 30+ years of water treatment expertise through Watermart, not assembled overnight by a dropshipping operation. Certification details for every system are listed on its product page, not hidden behind marketing copy. And our support continues long after the box arrives, because we take responsibility for your family's water quality.

illi Water sells three under-sink reverse osmosis systems and three drinking-water appliances for Canadian homes.

The Tankless RO System is the premium model, with on-demand flow at 800 GPD, alkaline remineralization, and a smart digital faucet. We also offer the countertop RO Hot & Cold Water Dispenser, an under-sink instant hot water dispenser and an under-sink water chiller. Everything ships free across Canada, and current prices are shown on each product page.
Do illi Water systems actually remove dangerous contaminants, or just improve taste?
Do illi Water systems actually remove dangerous contaminants, or just improve taste?
They do both, but the filtration goes well beyond taste. illi Water reverse osmosis systems remove up to 99% of contaminants including lead, chlorine, PFAS, fluoride, nitrates, pesticides and heavy metals, not just the impurities that affect how water smells or tastes. You can see the certification and contaminant details for each model on the reverse osmosis systems page.
