If you notice white floating particles in the water dispensed by the Xiaomi Instant Hot Water Dispenser, specific conditions can vary depending on the type of water used. If you are using purified water, these white particles are tiny air bubbles formed due to the rapid heating process. These bubbles are harmless and dissipate within about a minute. However, if you are using non-purified water, the white particles can be impurities or minerals present in the water. To ensure the best water quality and avoid these particles, it is recommended to use purified or filtered water.
