HTO Series

Complete Water Refining System For Your Home

With Hydrotech’s HTO Series (Hardness, Taste, Odour), rid your water of hardness minerals (calcium and magnesium). Plus, filter out bad tastes and odor caused by chlorine, chloramines or organic matter. Great for any home on municipal water!

The unique two tank system keeps the two media beds separate. This allows for more carbon contact which greatly improves the removal of chlorine, chloramines, and organics. Because the carbon typically needs to be replaced before the softening resin, the two tank system allows for easy cost effective replacement. You get the same benefit as a separate water softener and whole-house carbon filter for a much lower price as the single control valve operates both systems.

Now you can enjoy truly refined water throughout your home!
