Bacteria Shield

Bacteria Shield


You may be surprised to learn that up to 34% of all private wells test positive for E-coli or total coliform bacteria. Public city water can also be contaminated either at the source or on the way to your business. Some microscopic pathogens can even survive commonly applied disinfectants that are used in private wells or by water treatment plants. The Easy Water Bacteria Shield uses a targeted range of ultra violet light (UV) to inactivate harmful pathogens before they can enter your office.

Acid Shield

Acid Shield


Copper or steel plumbing can be corroded by acidic water, resulting in damage to plumbing fixtures, piping and valves. This may eventually cause premature failure of water-using equipment such as boilers and dish machines. Acid Shield uses a low-maintenance process and a natural calcium compound to raise the pH of acidic water.

Perfect for:

  • Protecting plumbing against pinhole leaks
  • Eliminating blue-green staining
  • Raising pH to enable proper removal of iron and manganese, where needed

No-Salt Conditioner


Keep your water handling equipment in top shape and running smoothly with the EasyWater No-Salt Conditioner. Hard water causes scale build-up in water handling equipment, which leads to costly repair or replacement, increased energy costs, and reduced water flow. The EasyWater No-Salt Conditioner eliminates hard water build-up without maintenance, salt or chemicals.

Series C Closed Loop Treatment System

The Series C Closed Loop Treatment System provides a cost effective, low maintenance, non-chemical treatment for controlling corrosion and scaling. The Series C system removes dissolved oxygen, filters suspended solids to 3 microns and prevents as well as removes insulating deposits.     Series-C Closed Loop Treatment System

Iron Shield

Iron Shield Max


Iron Shield®

Iron deposits build up in plumbing and water-using equipment and can result in costly maintenance and premature equipment failure. Iron and manganese can also cause discolored water and unsightly rust-colored or black stains on plumbing fixtures, laundry, and concrete walkways, driveways and parking lots. Iron Shield keeps both your plumbing and your image in top shape by oxidizing iron, manganese and hydrogen sulfide inside the tank, before they can do damage.
