Automobile Exhaust and Indoor Air Purification

Modern lifestyles involve spending 80-90% of time indoors, making indoor air quality crucial for health. Major indoor pollutants include:

1. Volatile Organic Compounds (VOCs): Common examples include aldehydes, benzene, and toluene.

2. Inhalable Particulate Matter and Harmful Inorganic Molecules: These include suspended dust particles, automotive exhaust, and pollutants from combustion processes like CO, nitrogen oxides, and sulfur dioxide.

3. Suspended Microorganisms: This category includes bacteria and viruses.

Technological advantages

The air first passes through a fiberglass pre-filter and then enters an adsorption and disinfection purifier. This purifier contains Longantai's self-developed materials with strong adsorption capabilities, such as activated carbon, aluminum oxide, silica gel, and molecular sieves. These materials effectively remove harmful components from the air, including pollutants and odors like automotive exhaust and cigarette smoke. Additionally, the purifier includes a small ozone generator that produces low-concentration ozone. This ozone mixes with the indoor air passing through the purifier to achieve disinfection and sterilization.
