Culligan

All of your hot water is 100% filtered

that you can drink. 


  • The Culligan we uses a 3M, 5-micron filter ​with graded density carbon block that traps large particles on the surface and finer particles through the media depth for a long service life. Remember, average human red blood cell is about 5 microns.


  • This food grade quality filter is made of Polypropylene filtration media, this range of compact filters is able to enhance taste and reduce odor, chlorine, lead and controls the formation of scale.

  • Above is a cartridge comparison before and after 6 months
  • NSF/ANSI 42 & 372 Certification by WQA against NSF/ANSI42. The filter reduces up to 99% of Chlorine, sand, rust, sediment, scale color and odor. Lead Free Certified by WQA against NSF/ANSI372.

  • The cartridge can filter up to 100,000 gallons depending on local water quality. Suggest replacing it every 6- 12 months for the average household of 3 people, 3 showers. This is dependent on the city water supply quality.

The best filter cartridge is made by 3M. Also needed is silicone o-ring grease.

LEARN WHY TANK HOT WATER HEATERS ARE BAD

  • A typical 50-gallon hot water tank heater, is only 38 to 50 percent efficient and will last only 8 to 10 years. Produces only 35 gallons of hot water.


  • Also, your hot water tank collects 8 to 10 lbs of sediment and toxins , which  you bathe in everyday and do not drink hot water from a tank heater...

This picture taken with a scope camera from inside a 7-year-old hot water tank heater.  You are looking at a buildup of calcium and other toxicants that you bathe in daily.

With our Rheem/Culligan tankless
hot water system
this will not happen.
