Water Filter System Basics (cont)
It is important to note that although these standards cover many contaminants and set up MINIMUM reduction requirements, a product does not have to remove ALL of the contaminants to earn NSF certification. The filter only has to reach the minimum requirement for the contaminants claimed by the manufacturer to receive certification.
You Must Read the Fine Print, Really!
To compare filters you have to look not only for the NSF certification, but you need to check each filter’s Performance Data Sheet to find
(1) the number of contaminants removed, and
(2) the real level of reduction achieved.
So while it is true that ALL CERTIFIED products meet minimum reduction requirements, some will perform better than others at removing contaminants.
This is where we come in.
