Find The Right Product For You

Some of us have harder water than others, and EWS generally considers 

6 grains (102 ppm or mg/l) of hardness to be on the lower end of 

hard water. Select 

YES

 if you have hard water issues such as excessive 

spotting or mineral build-up in pipes, faucets and water heaters.

CWL system 

 

Adjustable for 3/4” - 1 1/2” 

main water line. Up to 37 gpm.

If your city water is treated 

by chloramine this system 

 

can still be very effective for 

4 or less people with 4 or less 

bathrooms. 
The only difference may be 

how long the filtration media 

may last.
    With Chlorine up to 10 years 

    With Chloramine 7 years 
Either way you cannot go 

wrong. 
So the choice between the  

CWL SPECTRUM and the CWL-

CC-1465 can be a customer 

choice based on price point or 

longevity of filter media.

**

About 22% of people have tap water treated with chloramine (a corrosive combination of chlorine and ammonia). Chloramine requires more contact time (vs. chlorine) 

through a specialized filtration media to effectively filter it out of the water. EWS has designed systems specifically for handling chloramine (and does everything else the chlorine 

systems will do).  See the chart above to determine the right system for you, your family and your home.
