Activated carbon filters remove volatile organic compounds, odors, and heavy metals from liquids and gases. They operate on activated carbon's high surface area to adsorb impurities. They have proved helpful in air quality control and wastewater treatment. They are widely used within solvent-recovery systems to reduce emissions while maintaining regulation compliance.

HEPA filters are crucial in places where the environment requires more stringent air quality, including cleanrooms, hospitals, and laboratories. They capture 99.97 percent of particles 0.3 microns in size, ensuring that sensitive processes or products are not contaminated. Many industries producing semiconductor and pharmaceutical products have specific environments and may install HEPA filters to protect their operations from airborne particles.
