Air purifier negative ion HEPA filter

With the flip of a switch, you can fill your room with air that makes you feel like you're in a forest. This air purifier releases negative ions, known as the vitamins of air, and fills your room with clean air. It generates more than 10,000 negative ions per cubic centimeter. The HEPA filter captures tiny, invisible dust particles. Furthermore, the pleated filter increases the dust collection area, preventing a decrease in performance due to clogging and ensuring sustained dust collection. Source: https://www.amazon.co.jp/
