Using a TDS meter to measure water quality

TDS meters measure the conductivity of the water, which can help identify salts or other impurities which have positive charges. However, common disinfection by-products in water, such as chlorine, iron, chloramine etc, do not impact the conductivity of the water. So they would not be picked up by a TDS meter.

Put another way, TDS meters cannot detect toxic chemicals such as Chlorine or Chloramine, therefore they should not be relied on to measure water quality.

The best way to test the effectiveness of the shower filter would be to use a chlorine colorimeter or chlorine test strips.

How do I know if the filer is working?

Our products target harmful chemicals and byproducts in water. You can look for these as signs that the product is working:

• Reduced or eliminated chlorine smell
• Less dry itchy skin
• Stronger, more manageable hair
• Strong and healthy-looking nails
• Soap which lathers up more, to create more bubbles.
