A negative ion air purifier is a device that can provide fresh air, and it works by releasing negative ions to purify pollutants in the air.
Negative ions refer to air molecules or molecular clusters with a negative charge, which are capable of chemical reaction or physical adsorption with pollutants in the air, thereby removing harmful substances from the air.
Let's take a closer look at how ionizer air purifiers work.
Ionizers usually use ionizers or corona dischargers as generators for ions.
When air passes through these generators, the generators generate a high-voltage electric field that allows some of the electrons in the air molecules to gain enough energy to turn into negative ions with a negative charge.
These negative ions flow with the air and come into contact with airborne particulate matter or organic compounds.
When negative ions come into contact with contaminants, they are removed in several ways.
Negative ions are able to chemically react with particulate matter or contaminants, making them larger and more likely to settle or deposit on surfaces.
This chemical reaction can make the particulate matter in the air less susceptible, thus achieving the effect of purifying the air.
Negative ions are also able to react with volatile organic compounds (VOCs) in organic compounds to decompose or reduce them to become more stable substances.
Thirdly, negative ions can also remove contaminants by physical adsorption.
Negative ions have a negative charge that creates an electrostatic attraction on the surface of particles or pollutants in the air, which adsorbs them around the negative ions, preventing them from being released into the air again.
This physical adsorption capacity enables negative ions to effectively remove suspended particles, bacteria, viruses, etc.
Ionizer air purifiers also have some other additional features.
For example, negative ions can help improve the body's immune system, regulate the nervous system, and promote metabolism.
Negative ions can also reduce people's stress, improve sleep quality, and have antioxidant, antiseptic and other effects.
These additional features make ionizers widely used in comfortable homes, office environments, and health care.
To sum up, ionizers purify pollutants in the air by releasing negative ions.
Negative ions can react chemically or physically adsorb with pollutants to achieve the effect of removing pollutants.
Negative ions also have some additional functions, such as improving human health and providing a comfortable indoor environment.
