Visible Purity / Air Purifier

This is a design of innovative air purifier called Visible Purity.Its design inspiration comes from the fish tank. When we see the water in the fish tank become turbid, we know that we should change the water. Similarly, we should purify the air when the indoor air become epinephelos. However, the indoor air quality is not easy to be detected by the naked eyes. So we create the Visible Purity air purifier which is helpful for the visual observation of air quality.
