How is the importance of activated carbon used in Air purifier
Activated carbon is commonly used in high-quality air purifiers because it does a good job of removing harmful gases that HEPA filters can't deal with. Now let's look at the importance of activated carbon in air purification in homes and offices.
What materials of the activated carbon
Activated carbon filters were originally called HEGA(High Efficiency Gas Absorption) filters. It was first used to remove chemical gases. Activated carbon is mainly supplied in powder or pellet form. Granular activated carbon or powdered activated carbon is often used in air filters. These activated carbon particles have a much longer service life than powdered activated carbon. They are made by smashing solid blocks of carbon into smaller particles. Activated carbon made from coconut shell is superior to activated carbon made from wood or coal. The former has a larger surface area and moderate porosity. Coconut husks also produce less dust and fine carbon particles than wood and coal. Activated carbon must be made through an additional activation process that allows it to better capture gas molecules. Physical activation is performed by injecting hot air, carbon dioxide, or steam, and chemical activation is performed by soaking various reagents to form a grid of tiny pores that trap gas molecules.
The use of activated carbon
Activated carbon uses an adsorption process to remove contaminants from the air. It is almost like absorption, trapping the adsorbed matter in its own pores. Absorption occurs when a fluid passes through or enters a liquid or solid absorbent. At the same time, if the atoms, ions or molecules of the fluid adhere to the surface of the liquid or solid adsorbent, it is called adsorption.
What pollutants can activated carbon remove
Activated carbon is used in conjunction with air purifiers, especially HEPA air filters. It is built into air purifiers to capture and remove gaseous molecules and pollutants such as VOCs from the air that HEPA filters cannot handle. Such as tobacco smoke, volatile organic compounds (VOC), formaldehyde, benzene, naphthalene, chloroform and toluene.
Measure the performance of activated carbon in air purifier
Smoke and volatile organic compounds are the smallest and most dangerous particles. They easily enter the bloodstream through the lungs and are harmful to health when inhaled. That's why it's important to have an activated carbon filter in your air purifier. However, not all air purifiers with activated carbon filters have the same efficiency rating when it comes to removing these particles.
AIRBUS air purifiers, whether for home use air purifiers, or air purifiers used in other places, such as offices, hotels, yoga studios and car purifiers, all use the activated carbon high efficiency filter to achieve the best purification effect of air purifiers, which is favored and recommended by more customers and friends.
