Brondell H2O+ Pearl H620 Water Filtration System - Manual (Page 5)

The Pearl water filter system is not designed to remove beneficial minerals from
your drinking water . These minerals that occur naturally are a healthy part of your
drinking water and should remain . The Brondell Pearl water filter is designed to
dramatically reduce water-soluble harmful contaminants, including industrial
chemicals, pesticides, herbicides, turbidity, volatile organic compounds (VOC's),
and microorganisms, most of which cannot be "read" with a TDS reader .
Since these harmful components are water-soluble, they cannot be picked
up by a simple TDS meter . Contrary to its name (Total Dissolved Solids or TDS
Meter), these inexpensive products cannot detect most harmful water-soluble
contaminants . There is a major misconception that low TDS readings mean
healthy water and that is simply not always true .
The best method for testing the performance of a water filtration device is to have
a nationally recognized independent organization, such as WQA (Water Quality
Association) or NSF International, test and certify the products . The certified data
is then available in a Performance Data Sheet, which you should request from the
manufacturer . For more clarification of what the Pearl water filtration systems
does remove from your water, please see our Certified Performance Data Sheets
on pages 13-14 .
IMPORTANT NOTE ABOUT
“TDS METERS” AND TESTERS
Q) When I use a Total Dissolved Particle (TDS) reader to test my water
after it goes through the Pearl water filtration system, why don't the
levels of dissolved particles go down or decrease? I don’t think the
product is working.
