Buying a Drinking Water Filters and Reverse Osmosis Systems for you home or office can be confusing.

1. Knowing the water quality of your source water either through your municipality which is available on line and if well water make sure it is potable
2. From a well check for TDS (total dissolved solids) with a TDS 3 test meter and ask if there are any known hazardous contaminants in area well.
3. Usually if your water is under 200PPM total dissolved solids, carbon block with lead reduction will be sufficient, though there are heavy metal filters and arsenic filters as well as fluoride filters.  
4. Install the system, set aside about an hour of time.
5. Always follow installation instructions and remember to flush any carbon fines from new filters.
