What is a Total Dissolved Solids Filter?

Sun, 02 Nov 2025 18:26:19 +0000

A "total dissolved solids filter" refers to any water filtration system designed to reduce or remove TDS from water. It's not a specific type of filter—it's a category describing filters that target dissolved contaminants.

Key Technologies That Reduce TDS:
1. Ion Exchange Filters (Like ZeroWater)

TDS Reduction: 99.6% (achieves 0 ppm)
Uses resin beads to exchange contaminant ions for hydrogen/hydroxide ions
Most effective for complete TDS removal
Example: ZeroWater 5-stage filtration

2. Reverse Osmosis (RO) Systems

TDS Reduction: 85-95% (typically 50-100 ppm remaining)
Forces water through semi-permeable membrane
Removes most dissolved solids but wastes water
Requires installation under sink

3. Distillation

TDS Reduction: 99%+
Boils water and collects condensed steam
Very slow and energy-intensive
Not practical for daily drinking water

4. Deionization (DI) Filters

TDS Reduction: 99%+
Industrial/lab-grade technology
Similar to ion exchange
Expensive for home use

If someone wants a "total dissolved solids filter," they need:

Ion exchange filtration (ZeroWater) - Most effective, affordable, no installation
Reverse osmosis - Very effective but expensive and wasteful
NOT standard carbon filters - These don't significantly reduce TDS
