New Filter & Used Filter

Water Softeners

Hard water commonly seen as water spot/stains is a common problem across our beautiful islands of Hawaii. Surprisingly, water quality will differ between districts. For example, water hardness levels will be different in Ewa Beach when compared to Kapolei, Makakilo, Hawaii Kai and other surrounding areas. Typically hard water causes water spots in shower glass/tile, hardens as a ring around the toilet, leaves yucky soap scum in showers/tubs and leaves you with dry/itchy skin. Water containing high concentrations of calcium and magnesium is to blame but there is a solution. Our water softeners remove those unwanted minerals leaving your water clean and fresh. Water spots, dry/itchy skin, ring around the toilet and other nuisances caused by hard water will be a thing of the past.

Reduces water stains on your fixtures and corrosion in your plumbing.

Increases the performance and longevity of your water using appliances (water heater, washing machine, dishwashers and water fixtures)

Remove foul odors and taste caused by minerals and high chlorine levels and improves soap’s ability to clean.
