Why is my TDS meter reading at higher levels?Updated 2 months ago

This is an excellent question, around measuring water efficacy with TDS meters for our pitchers. 

Total Dissolved Solids (TDS) is a term used to describe the inorganic salts and small amounts of organic matter present in water. TDS tests do not test for contaminants such as heavy metals, chemicals, microplastics, bacteria, or parasites. Bottled mineral water can have a high TDS reading because of the good mineral content.

Furthermore, for values below 2,000 mg/l, there is no scientific evidence that TDS affects health.  

But, if the TDS has been raised after filtration, it would be because of the below: 

• The meter measures electrical conductivity in water and this EC of water is then converted into TDS.  Because EC depends on the dissolved solids, ionic strength, temperature measurements, etc., and our Home product does not remove minerals but traps and replaces heavy metals in effluent water with common ions such as Na+/H+, this might change the EC levels in the water, which may also contribute to a change in a higher TDS level. 

All of our products have full evidence dossiers that show independent lab testing on efficacy based on the protocols recommended by the US EPA which is not based on TDS but rather actual percentage removal of contaminants.
