Criteria to Consider When Selecting a Drinking Water Device
There are four main criteria to consider when evaluating a drinking water filter:
1. Who is the system certified by? What is the system certified to remove?
Tested to NSF standards means the system was tested and failed the NSF test and is not certified by NSF. A big difference!
2. What is the initial outlay for the system and what is the annual upkeep?
3. How long has the company been in business?
4. Is the warranty being given away or offered? In other words, are you paying a premium for the warranty and does the company stand behind the system.
