Water Treatment Systems

Drinking your home’s water shouldn’t be risky…

…nor should taking a shower, or washing your vegetables. But as you probably know, the water coming into your home contains more than H2O. It also contains an array of contaminants that may include lead, arsenic, chromium hexavalent, trihalomethanes, PFAS, industrial and agricultural runoff, pharmaceuticals, not to mention chlorine, fluoride and iron.

Your water softener doesn’t protect your family.

Your water utility doesn’t protect your family.

Imagine… great-tasting, crystal-clear, odor-free, virtually contaminant-free water for drinking, bathing and cooking.

Capital Well Offers Premium Water Appliances to give your family clean, fresh water throughout your entire home.

What is your water worry?

No matter your water worry, Capital Well can install a Water Appliance to put your mind at ease. It is the whole-house solution that does it all.

Dangerous contaminants

Capital Well’s Premium Water Appliance will give you virtually contaminant-free water throughout your entire home. No other home water device removes contaminants at these levels.

Our Water Appliance offerings have been third party tested to NSF 58 standards for the removal of:

Lead – less than 1 ppb (part per billion)
Chromium Hexavalent – less than 1 ppb
PFOA & PFOS – less than .02 ppb
Arsenic – less than .5 ppb
Iron* – .02 ppm
Chloroform – less than 2 ppb
Nitrate – 0.9 ppm (part per million)
Nitrite – 0.2 ppm
Fluoride – 0.8 ppm

*Water with iron levels above 3 ppm requires pre-filtering


Chlorine plays an important role in municipal water systems – killing bacteria that cause waterborne diseases. But, chlorine can also add unwanted smell and taste, and dry your skin and hair. Plus, it’s really not something you should be drinking or bathing in. Get the chlorine out and give your family the fresh-tasting, odor-free, virtually chlorine-free water from every tap.


A water softener only softens water. It does little to purify it. A water softener requires salt to work. The residual salt in the water makes you feel slimy after a shower. It etches your glassware. Worst of all, it leaches into groundwater causing serious environmental impact. In fact, communities across the country are passing ordinances banning the use of salt in water softeners, making homeowners switch to potassium chloride, a costly alternative. Why break your back lugging around heavy bags of salt and feeding it into a device that does only one thing – soften? Our systems can removes hardness (to less than 1 ppm) – without salt. No more etched glassware. No more slimy feeling skin after a shower. No more salt bags. Ever.
