How Do Non-Filter Air Purifiers Work to Remove Contaminants?

Non-filter air purifiers utilize various technologies to remove contaminants from the air without traditional filters.

• Ionizers: Ionizers release charged ions into the air that attach to airborne particles, such as dust and allergens, causing them to clump together. These larger particles then either fall to the ground or are attracted to oppositely charged surfaces, effectively reducing their presence in the air.
• UV-C Light Purifiers: These devices use ultraviolet light to kill or deactivate bacteria, viruses, and mold spores. The UV-C light disrupts the DNA of these microorganisms, rendering them harmless and preventing them from reproducing, thus improving overall air quality.
• Ozone Generators: Ozone generators produce ozone, a molecule that can neutralize various pollutants, including odors and volatile organic compounds (VOCs). While effective in small amounts, high concentrations of ozone can be harmful to health, so these devices should be used with caution.
• Photocatalytic Oxidation (PCO): PCO purifiers use a combination of UV light and a photocatalyst, usually titanium dioxide, to oxidize and break down organic pollutants into harmless compounds. This process not only eliminates odors but also reduces harmful chemicals in the air.
• Electrostatic Precipitators: These devices use electrical charges to attract and capture particles from the air. The air passes through a series of charged plates that attract dust, smoke, and other contaminants, effectively cleaning the air without the need for replaceable filters.
