Reverse osmosis is one of the most effective ways to purify your home’s water supply.
By forcing water through specialized membranes, these systems remove contaminants like lead, chlorine, and PFOA — leaving you with safer, fresher water for drinking, cooking, and everyday use.
At Croix Crystal, we install trusted Aqua Systems reverse osmosis units designed for long-lasting performance. Our technicians handle everything from system sizing and installation to maintenance, so you can enjoy peace of mind knowing your family has access to the cleanest water possible.
With the right reverse osmosis system in place, you’ll notice a clear difference in both taste and quality. From morning coffee to family meals, purified water makes every sip and recipe better. Plus, it reduces scale and buildup in your kitchen appliances, helping them last longer and perform more efficiently.
Say goodbye to bottled water runs. With reverse osmosis, you’ll have purified water on demand, straight from your tap.

Water treated with reverse osmosis isn’t just safer — it’s noticeably better tasting. Our team installs and maintains reverse osmosis systems across Western Wisconsin and the Twin Cities, ensuring you get consistent, purified water at home.
