Generates negative ions to refresh the indoor environment Negative ions are molecules that exist in specific environments such as mountains, waterfalls, and seas, and are tasteless, odorless, and invisible. It is said that when negative ions enter our bodies, they have a relaxing effect and soothe our mood. Negative ions generated by air purifiers attach to floating particles and their weight allows them to be more easily adsorbed by filters. Dirt particles that fall to the ground due to their weight can be easily sucked up with a vacuum cleaner, so they do not enter the human body.
