1. Working principle of activated carbon honeycomb
Activated carbon honeycomb is a porous structure made of activated carbon material. This structure is characterized by a large number of tiny pores, which can effectively adsorb harmful gases and pollutants in the air. When air passes through the activated carbon honeycomb, harmful substances in the air such as formaldehyde, ammonia, benzene, volatile organic compounds (VOCs), etc. will be adsorbed and fixed by the porous surface of the activated carbon, thereby purifying the air.

Unlike traditional HEPA filters that mainly rely on physical filtration, activated carbon honeycombs rely on their powerful chemical adsorption function to deal with gaseous pollutants in the air. Therefore, the combination of Round Design HEPA Filter and activated carbon honeycomb can achieve dual purification of particulate matter and gaseous pollutants in the air, ensuring the overall improvement of air quality.

2. Ability to remove harmful gases
The activated carbon honeycomb technology carried in Round Design HEPA Filter is mainly used to remove harmful gases in the air. Common harmful gases include:

Formaldehyde: Formaldehyde is a toxic volatile organic compound that is widely present in building materials, furniture and some daily necessities. Long-term exposure to formaldehyde poses a serious threat to human health, especially damage to the respiratory and immune systems. Activated carbon honeycombs can effectively absorb formaldehyde molecules in the air, thereby reducing its concentration and protecting indoor air health.

Ammonia and benzene: Ammonia is commonly found in daily necessities such as detergents and air fresheners, while benzene is widely found in industrial gases and certain plastic products. Activated carbon honeycombs can quickly absorb these toxic gases, reduce their harm to the human body, and keep the indoor air fresh.

Cigarette smell: Cigarettes contain a large amount of harmful substances, which are not only harmful to smokers, but also the impact of secondhand smoke on people around them should not be underestimated. The powerful adsorption function of activated carbon honeycombs can effectively remove smoke and harmful substances in the air, providing users with fresh indoor air.

3. Remove odors and improve indoor air quality
Activated carbon honeycombs can effectively remove some common odors while removing harmful gases in the air. Kitchen fumes, pet odors, moldy odors, etc. may become sources of indoor air pollution, affecting the health and quality of life of family members. By working with the Round Design HEPA Filter, the activated carbon honeycomb can effectively adsorb and purify these odors, thereby improving the indoor air environment and enhancing living comfort.

4. Enhance the overall performance of the air purifier
Compared with a single HEPA filter, the round design HEPA filter combined with the activated carbon honeycomb has a significant performance advantage. The Round Design HEPA Filter is good at filtering particulate matter such as dust, pollen, pet hair, etc., while the activated carbon honeycomb can handle gaseous pollutants. The two complement each other and provide a more comprehensive air purification solution.

5. Extend the service life of the HEPA filter
In traditional air purifiers, the HEPA filter usually needs to be replaced regularly, and the round design HEPA filter using activated carbon honeycomb can extend the service life of the HEPA filter. The activated carbon honeycomb reduces the accumulation of particulate matter on the Round Design HEPA Filter by adsorbing of the gaseous pollutants, thereby avoiding the situation where the HEPA filter reduces efficiency due to clogging.

6. Combined with cold catalyst to improve the sterilization effect
Some high-end models of Round Design HEPA Filter also combine cold catalyst technology to further enhance its air purification function. The cold catalyst can inhibit and kill harmful bacteria in the air, such as Staphylococcus aureus, Colon Bacillus, etc., ensuring that there are no potential pathogens in the air. The combination of activated carbon honeycomb and cold catalyst further improves the sterilization and disinfection function of the air purifier, making it a multifunctional and efficient air purification device.
