Water Softeners

We offer the best and most efficienct water softeners available. We provide systems awarded the Water Quality Association's gold seal. Many of our systems last more than a decade in use without any major repairs or maintenance.

Benefits of using a water softener include:

  • Removing impurities, bad taste, and odor from tap water.
  • Removing hard water responsible for damaging hair and clogging skin pores.
  • Saving money on plumbing costs, hot water energy, and cleaning costs.
  • Removing scale from pipes, appliances, and places like around shower heads.
  • Extending the life of your appliances and plumbing.
  • Eliminating soap scum, leaving dishes crystal clear and reducing time spent cleaning.

Reverse-osmosis Systems

Reverse osmosis systems are used to filter water at the tap and provide purified drinking water with better-than-bottled-water quality. Reverse osmosis system filters only have to be changed once a year with moderate use, meaning you will have an entire year of crystal clear purified water from your sink with little to no upkeep.

Benefits of using a reverse osmosis system include:

  • Purified, bottled water quality drinking water direct from your sink.
  • Food and beverages prepared with purified water will taste better.
  • Crystal clear ice.
  • Save money filling your watter bottle right from the tap.

Salt-free, Non-electric Systems

These systems provide water conditioning without the use of electricity or salt. Great for preventing buildup of scale in water pipes and appliances and removing hard water spots as well as other chemicals.

Benefits of using a salt-free, non-electric system:

  • Removing buildup of scale from pipes, appliances, showerheads, etc.
  • Saving energy and costs of resupplying filtration media.
  • Extending the life of appliances and pipes.
  • Removing scale makes water better for your skin and hair.
