Activated Carbon

Activated Carbon filters are designed to remove chemical fumes, odors, vapors and volatile organic compounds (VOCs) from the air through adsorption, a process where contaminants are trapped within the filter’s highly porous carbon media. Commonly used in ductless fume hoods, fume extractors and air purification systems, these filters help improve indoor air quality and provide effective source-capture filtration for laboratory, industrial, manufacturing and pharmaceutical applications.

• Removes odors, chemical fumes and VOCs
• High surface area for efficient contaminant capture
• Helps improve indoor air quality and operator safety
• Available in specialty blends for specific chemicals
• Ideal for ductless filtration and source-capture systems

Acid/Gas

Acid/Gas filters are specially formulated to capture and neutralize corrosive chemical fumes, acid vapors and hazardous gases generated during laboratory, industrial and chemical processing applications. Using chemically treated filtration media, these filters help improve indoor air quality and protect operators by effectively removing airborne contaminants at the source in ductless fume hoods and fume extraction systems.

• Designed for acid fumes and corrosive gas applications
• Helps capture hazardous airborne chemical vapors
• Supports improved operator safety and air quality
• Commonly used in laboratories, manufacturing and chemical processing
• Ideal for ductless filtration and source-capture systems

Ammonia

Ammonia filters are specifically designed to capture and neutralize ammonia vapors and related alkaline fumes generated during laboratory, industrial, refrigeration and chemical processing applications. Utilizing specially treated filtration media, these filters help improve indoor air quality and protect operators by removing harmful airborne contaminants at the source in ductless fume hoods and fume extraction systems.

• Designed for ammonia and alkaline vapor applications
• Helps capture irritating and hazardous airborne fumes
• Supports improved operator safety and air quality
• Commonly used in laboratories, refrigeration and chemical processing
• Ideal for ductless filtration and source-capture systems

Formaldehyde

Formaldehyde filters are specially engineered to capture and neutralize formaldehyde vapors and other aldehyde-based chemical fumes generated during laboratory, medical, manufacturing and preservation processes. Using chemically treated filtration media, these filters help improve indoor air quality and provide effective source-capture protection in ductless fume hoods and fume extraction systems.

• Designed specifically for formaldehyde and aldehyde vapor applications
• Helps capture hazardous airborne chemical fumes and odors
• Supports improved operator safety and indoor air quality
• Commonly used in laboratories, healthcare and industrial environments
• Ideal for ductless filtration and source-capture systems
