¡°853(2750) – Used for removing VOCS, SO2, NO2, ozone, H2S. The 853 media is most effective for VOCS, and it has considerable capacity for common outdoor pollutants such as SO2, NO2, ozone, H2S. The 853 media is also very effective for removing boron (e.g., emission from conventional HEPA/ULPA filters)
¡°147(2752) – Used for removing ammonia and amines (nitrogen-containing organic compounds such as NMP, monoethylamine, morpholine, cyclohexylamine, dimethylamine, trimethylamine, diethylamine, HMDS and etc.)
¡°875(2751) Media - Used to remove acids such as HCI, HF, H2SO4, and is also very effective for removing SO2, NO2, ozone, H2S. This medial is better than 853 media.
¡°Both 147 and 875 media can remove VOCS. However, the life span of 147 media is reduced to 1/2 as compared to 853 media.

1.Four main techniques for controlling odor and gas contaminants: Gas Mask, Combustion, Ventilation and Removal.
2.Granular Media is used for controlling gas contaminants by Adsorption and Oxidation.
3.Chemical Filter can be used to remove molecular contaminants by Adsorption and Oxidation.
4.Adsorption: When gaseous or liquid molecules reach adsorbent surface but without any chemical reaction, the phenomenon is called physical adsorption or physisorption.
5.Sorption: When gaseous or liquid molecules reach adsorbent surface and happen chemical reaction, the phenomenon is called Sorption.
6.The bowling Point of adsorptive materials, vapor pressure and active are the main factor affecting the initial efficiency. The materials which boiling point higher than 100 ¢J, will be in the liquid state at room temperature, and is easily to be adsorbed and condensed in the adsorbent surface.
7.In molecular contaminant system, initial contaminant removal efficiency is not depending on particle weight, size, total surface area or carbon activity. Two important parameters for determining initial efficiency is the total surface area of chemicals and absorbents.
8.The surface area increased when the dimensions of carbon are getting smaller. Particle size can be very small, even though it just becomes carbon dust. It also creates problems of escaping into the air, or due to packing tightly and causes high pressure drop.
9.Temperature also can affect adsorption efficiency. The higher the temperature the lower the adsorption efficiency. Moisture will occupy carbon’s adsorption surface, therefore adsorption efficiency is poor in wet weather (like rainy day).
10.For Material with small molecular weight or boiling point lower than ambient temperature, they cannot condensate as liquid; thus cannot attach on the surface of adsorbent, and they will be oxidized in air or substituted by other materials on the surface of adsorbent.
