Specialty Blended Filters
An air filtration system is the preferred way to eliminate harmful gases, fumes and undesired odors from the environment and application. However, standard particle filters do not hold the necessary capabilities to remove harmful gaseous pollutants.
Our custom specialty blended filters are highly efficient at removing hazardous fumes, odors, and severely toxic chemicals. By utilizing activated carbon as the host material, we impregnate the carbon with high-grade proprietary reagents to achieve superior results for the adsorption of airborne gasses.
It is imperative to remember that due to the surface area of the activated carbon that airflow can become compromised in some applications.

- Ammonia Removal from Air
- Aldehyde Removal
Acid Gas Removal
High-grade impregnated activated carbon for acid gas removal. Our acid gas removal process separates highly toxic CO2 and sometimes deadly H2S acid gases from natural gas streams through the adsorption process by utilizing a custom specialty blended filter.
The proprietary reagents used to impregnate this activated carbon show a high efficiency in the removal of airborne acid gases, and contain no heavy metals, such as, copper, lead, or mercury, that could lead to further hazards or harm.

Mercury Removal
High-grade impregnated activated carbon for mercury removal. One of the methods of removing mercury vapor from gases and air streams is to use high efficiency adsorption filters that do not allow the vapor to build and dissolve, recreating an emission. Therefore, it is critical to ensure that the carbon used in the application is regarded as “high-grade” and holds a minimum hardness (ball pan) efficiency of 95%.
The proprietary reagents used to impregnate this activated carbon show a high efficiency in the removal of mercury vapors, and contain no heavy metals, such as, copper, lead, or mercury, that could lead to further hazards or harm.
