What is TDS on earth?
A high TDS reading is not a direct indication of the bad water quality, but an indication of more ions contained in the water.
Salty water has a higher TDS reading than tap water because of its sodium ions.  Juice has a higher TDS reading than tap water because of its ions of ingredient. Mineral water also has a higher TDS reading than tap water because of its healthy mineral ions.
Tap water in most areas is safe. Tap water contains certain harmless ions or healthy mineral ions.  Our water filter, like all the original OEM brands, retains these ions in water.  
When you use a TDS meter to get the reading of tap water and the purified water of our filter, you can find the readings have no big changes.  All the refrigerator water filters are designed not to reduce these ions, but reduce the main problem of tap water-Chlorine, Chloride, Odor, etc.
