Home air purifying ventilation fans are primarily used to remove indoor air pollutants (generally including dust, pollen, odors, formaldehyde and other, bacteria, allergens, etc.) and effectively improve air cleanliness. Air purifiers typically consist of a high-voltage circuit, a negative ion generator, a fan, and an air filter.
When the purifier is running, the fan inside the machine circulates air within the room or vehicle. Polluted air is filtered through the air filter, removing or adsorbing various pollutants. Then, the negative ion generator, located at the air outlet, continuously ionizes the air, generating a large number of negative ions. These negative ions are then emitted by the small fan, forming a negative ion stream, thus achieving the purpose of cleaning and purifying the air.
