What type of water should be avoided in facial steamers to prevent damage?

The type of water that should be avoided in facial steamers is tap water, and this is primarily due to the minerals and impurities it contains. Tap water typically includes calcium, magnesium, and other minerals that can build up inside the steamer over time. This mineral buildup can lead to scaling, which may damage the internal components of the machine, affecting its performance and potentially causing a malfunction.

Using distilled water is a better choice because it has been purified to remove any minerals and impurities, ensuring that no buildup occurs in the steamer. Filtered water, while cleaner than tap water, might still contain some minerals depending on the filtration process used. Mineral water is typically high in various minerals, which can further exacerbate the risk of buildup. Therefore, avoiding tap water is essential for maintaining the longevity and efficiency of facial steamers.
