​Greenwave conducts three types of tests:

Chlorine test: 

Through color reaction, this simplified method allows to know whether the water contains too much chlorine within a few minutes.

TDS test: 

TDS stands for Total Dissolved Solids. For this method, a TDS meter is used to determine the amount of pollutants in the water.

Air scanner: 

A portable equipment to test the level of PM2.5 and PM0.3 in the indoor environment. It can also be used to test how effective your air purifier works.

​Laboratory tests will give you much more information than simple ones, giving you the precise quantity of each tested pollutants.

These tests are however more time-consuming and costly, but allow for more accurate results.​
