A TDS meter measures total dissolved solids in water, a quick way to check a filter's performance. Here is the Whittier guide.
What TDS is
Total dissolved solids is the combined amount of minerals, salts, and metals dissolved in the water, measured in parts per million.
What it tells you
A TDS reading shows whether a reverse osmosis filter is working and roughly how mineral-heavy the water is.
What it does not
TDS does not identify specific contaminants or whether the water is safe — it is a general indicator, not a safety test.
Using it
Compare the tap reading to the filtered reading to confirm your filter is removing solids. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Whittier, this is a handy check.
