Based on repeated customer requests, we have conducted filtration efficiency tests for other heavy metals that are found in the water sources of many of you.We decided to have independent laboratory tests for arsenic, aluminium and antimony, which this time were carried out at the Veterinary and Food Institute in Košice.

We have also added other filter jugs commonly available on the market for comparison. The input water before filtration was laboratory contaminated to the limit permitted values and after filtering the water, re-analyses of all samples were carried out.

See the results of the individual analyses:

 

TEST PROTOCOLS:
