Certifications You Can Trust
When you’re choosing a water system for your home, you shouldn’t have to take a leap of faith. That’s why every illiWater product is backed by certifications that prove it does exactly what we say it does.
Each system is NSF/ANSI certified, which means it has passed independent testing for contaminant reduction, material safety, and long-term performance. In plain terms: it removes what it promises to remove, and it’s built to last in real homes, not just in labs.
We also design with BPA-free components and lead-free faucets, so everything that touches your water is safe by design. On select models, you’ll also find WQA certifications for sustainability, an extra layer of assurance that your system is both effective and environmentally responsible.
These aren’t just technical details — they’re our way of saying you can pour every glass with confidence, knowing the science and the standards are working for you in the background.
