Since its founding, Sharp has launched a number of "firsts in Japan" and "world's firsts" in the fields of radios, solar cells, and liquid crystal displays. At present, Sharp is a large-scale integrated electronic information company. Sharp car air purifier adopts plasma space purification technology, and the released ions have a good inhibitory effect on bacteria in the air in the car. At the same time, it is equipped with a triple filter for excellent purification ability. Unfortunately, the price is more expensive, 1799 yuan, and it takes about 200 yuan to replace the filter, which is suitable for high-end users.
