How do you check the quality of filtered water? What elements must be present?

The most correct way to check the quality of water is to make an analysis of its compliance with "SanPiN 220.127.116.114-01 Drinking Water". At home to perform such an analysis without special reagents and skills is impossible.
The easiest way to conduct instrumental study of water at home is to check the electrical conductivity with a household TDS-meter. But this method only makes practical sense for testing the performance of a reverse osmosis filter. Т.к. It is the only household filter that reduces mineralization.
As practice shows, people who use filters for a long time, begin to determine the exhaustion of the cartridges by taste.
