TDS stands for Total Dissolved Solids and represents the total concentration of dissolved substances in water.

Countertop reverse osmosis water filtration system can be set up in less than 10 minutes without plumbing or drilling for maximum convenience.

TDS value of water before & after purification: Both of them are displayed in real time. If you use the water tank mode, there will be waste water flowing back to the water tank, and the water concentration in the water tank will be changed, so the displayed PPM value will be changed too.
