Best Water Purifier for 400 TDS

ModerateModerate TDS

Quick Summary

At 400 TDS, water can taste distinctly salty or metallic. An RO purifier becomes highly recommended at this level to bring the dissolved solids down to a more palatable 50-100 ppm range. Make sure to choose an RO system that includes UV purification to handle any biological contaminants.

Top Recommended Technology

RO + UV

A RO + UV system is the most efficient and safe choice for water measuring at 400 TDS.

Find the Best Purifier

Why this recommendation?

Choosing the right water purifier technology is entirely dependent on your Total Dissolved Solids (TDS) level.

  • Below 250 TDS: Using an RO wastes water and removes essential minerals. A UV/UF system is sufficient.
  • 250 - 500 TDS: Taste becomes an issue. RO is recommended but a Mineralizer (MTDS) is crucial to maintain pH and health.
  • Above 500 TDS: RO is absolutely necessary to remove heavy metals and excessive salts.

Since your water has a TDS of 400 ppm, our engineering team strongly recommends investing in a RO + UV system.
