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.

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 5-year warranty. Big box stores can't connect you with a water expert at midnight or help you troubleshoot a filter replacement over email.

Our team is available before, during, and after your purchase, day or night. Whether you need help choosing the right system, guidance through installation, a filter replacement reminder, or a warranty claim processed, there's always someone available to help. You'll never be left on hold with a chatbot after spending hundreds of dollars on a system.

Every illi Water system is independently tested and certified to NSF/ANSI standards the same benchmarks used by regulators and health authorities worldwide to verify contaminant removal and material safety. Our systems are also backed by a 90-day satisfaction guarantee and a 5-year warranty, which means we stand behind every unit we sell. If a product didn't perform, we wouldn't be able to offer that kind of protection. You can explore our full reverse osmosis systems range to see certifications listed per model.

Yes. Every illi Water system comes with a 90-day satisfaction guarantee install it, use it with your family, and if it's not right for your home for any reason, return it within 90 days for a full refund. No restocking fees. We also offer Shop Now – Pay Later at checkout, so you can spread the cost over easy monthly instalments rather than paying everything upfront.

We ship free to every province and territory in Canada. Orders are processed within 1–2 business days, and you'll receive tracking information as soon as your order is on its way. If you have any questions about delivery to your specific area, our support team is available around the clock to help.

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. Every performance claim is backed by independent NSF/ANSI certification, not just marketing copy. And our post-purchase support is genuinely available 24/7, not just during business hours. We're not just selling a product; we're taking responsibility for your family's water quality long after the box arrives.

illi Water currently sells three under-sink reverse osmosis systems for Canadian homes, ranging from $379.99 to $1,299.99 CAD. The Standard RO System is the entry-level option with 5–7 customisable filtration stages. The Pentair RO System is a mid-range NSF triple-certified unit with a 41% water recovery rate. The Tankless RO System is the premium model, with on-demand flow at 800 GPD, alkaline remineralization, and a smart digital faucet. All three ship free across Canada.

They do both, but the filtration goes well beyond taste. Every illi Water reverse osmosis system removes up to 99% of contaminants including lead, chlorine, PFAS, fluoride, nitrates, pesticides, heavy metals, and bacteria not just the impurities that affect how water smells or tastes. All performance claims are verified by independent NSF/ANSI certified laboratories, so there's no guesswork involved. You can see the full contaminant breakdown for each model on the reverse osmosis systems page.
