Filter contains a combination of a patented 13 natural minerals.
Replace the top filter with a new one after 6–12 months (depending on water hardness) if you pour 2–3 litres of water into the AQUA SANITAS bottle every day. If the water is very hard, we advise you to replace the filter every 6 months. When replacing the filter, activate the new one in the same way you activated the AQUA SANITAS bottle for the first time.
