Carbon Filters
Activated carbon has special properties that allow it to remove volatile organic compounds (VOCs), odors, and other gaseous pollutants from the air. It accomplishes this in a way that is different from other air purifiers like HEPA that only filter particle pollution from the air. Carbon air filters trap gas molecules on a bed of charcoal, a process that has a surprisingly colorful history. Here you will dive deep into how they work. Then you can consider if using a carbon air filter will meet your needs by examining its advantages and drawbacks.

Permanent Filters
The Airex Filter metal panels can be used as heavy duty filters in comfort ventilation, in oil mist separators, suction silencers, vibration silencers and seals. The metal panels are manufactured in a wide variety of materials, for example aluminum, stainless/acid-proof steel, galvanized steel and copper in most shapes and dimensions.

Ashrae Filters
ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) standard filters are mainly used in HVAC air handlers and clean room housing units. They are made with various efficiencies also known as Merv rating. CFS sells ASHRAE standard filters in efficiencies of 65% (Merv 11), 85% (Merv 13), and 95% (Merv 14). If you need a different efficiency than what is listed above we can special order the filter for you.
