How do I prepare the NEFRIIT LOODUSLIK VEEFILTER stones for their first use?

Since these are natural mineral stones, they may carry fine dust or residue from the cutting and polishing process. It is essential to clean them before introducing them to your drinking water. Rinse the stones thoroughly under cool, running tap water. You can gently rub them with your hands or use a soft brush to remove any visible particles. After rinsing, let them air dry on a clean towel or place them directly into your water container for the first time. This initial step ensures that no manufacturing debris affects the taste or clarity of your water.

Once cleaned, the stones are ready to be used. Simply place them in a glass, jug, or bottle of water. The porous, fibrous structure of the jade will interact with the water as it rests. This low-tech approach allows the mineral surface to condition the water, which many users find results in a softer, fresher taste compared to strongly processed water. The stones are reusable, so you do not need to replace them after a single use.
