Evidence, clearly explained

Laboratory reports and testing.

This page brings together the testing basis and product-specific evidence for BLACKWATER water filtration systems. Full protocols and individual measured parameters will be added here as publication copies become available.

Accreditation annexD-PL-21499-01-01

Wasserproben Lab GmbH performed the product testing. The laboratory is accredited to DIN EN ISO/IEC 17025:2018 for the examination scope specified in certificate annex D-PL-21499-01-01. Accreditation applies to that defined scope; it should not be read as a blanket certification of every product claim.

01

How to read a test

A useful report identifies the tested model, sample date, inlet water, test method, individual parameters, detection limits and results. Percentage reduction without starting and final values provides incomplete context.

02

What results do not mean

A result obtained under defined laboratory conditions does not guarantee identical values in every home. Pressure, temperature, local water chemistry, installation, usage and filter condition affect performance.

03

Product evidence versus general RO capability

Reverse osmosis as a technology can reduce many dissolved substances and fine particles. A claim about a particular BLACKWATER model should nevertheless be tied to the parameters and conditions in its product-specific documentation.
