3. Pre-Filters
4. Ionizers
5. Photocatalytic Oxidation
6. UV Light Filters

Each of these technologies plays a distinct role in air purification and they all enhance the overall efficiency of air purifiers.

1. HEPA Filters:
   HEPA filters stand for High-Efficiency Particulate Air filters. They can trap at least 99.97% of particles that are 0.3 microns in diameter. This includes dust, pollen, and pet dander. Studies show that HEPA filters improve air quality significantly in homes, especially for allergy sufferers. For instance, a study by the American College of Allergy, Asthma, and Immunology indicated that the use of HEPA filters reduced allergy symptoms by up to 60%.

2. Activated Carbon Filters:
   Activated carbon filters absorb odors, smoke, and volatile organic compounds (VOCs) through a process called adsorption. They contain a large surface area that attracts and binds harmful substances. Research conducted by the Blueair company indicates that activated carbon filters are particularly effective in urban areas where air pollution levels are high.

3. Pre-Filters:
   Pre-filters capture larger particles like lint and hair before they reach the main filter. This extends the life of the HEPA or carbon filters. Most Japanese air purifiers come equipped with washable pre-filters, which reduce operating costs and maintenance frequencies.

4. Ionizers:
   Ionizers release negatively charged ions into the air. These ions attach to positive particles like dust, allowing them to clump together and fall to the ground. While some studies support their use, opinions vary; some experts caution that ionizers may produce ozone, which can be harmful to health in larger concentrations.

5. Photocatalytic Oxidation:
   Photocatalytic oxidation employs a catalyst, usually titanium dioxide, activated by UV light. This process breaks down organic pollutants and disinfects the air. A study published in the Journal of Hazardous Materials in 2012 highlighted its effectiveness in removing bacteria and viruses from air.

6. UV Light Filters:
   UV light filters use ultraviolet light to kill or deactivate bacteria, viruses, and other microorganisms. Using UV light can enhance sterilization efforts, making air purifiers more comprehensive in air sanitation. Research in the journal Indoor Air implies that these filters can significantly reduce the transmission of airborne diseases.

These various technologies can work in tandem to ensure higher efficiency and better air quality in Japanese air purifiers. Each technology has its advantages and limitations, which informs consumer preference, depending on specific air quality needs.
