At Air Box, we understand that one size does not fit all when it comes to air filtration. That’s why we specialize in creating custom-built solutions that cater to the unique needs of your facility. When the demand exceeds the capabilities of our standard-sized Air Box Stealth units, we collaborate with you to engineer the most effective custom air filtration system for your space.

Tailored Performance:

Our custom Air Box designs are not just functional; they are highly efficient, delivering air exchange rates ranging from 50 CFM to an impressive 200,000 CFM. Whether you’re dealing with persistent odours or specific air pollutants, our activated charcoal carbon filters excel at obliterating unwanted smells, while our airtight Air Box design ensures 100% utilization of the filter surface.

Versatility in Filtration:

With over a dozen different substrates and custom media options, we offer a versatile range of filters and media to address your specific air filtration and odour control requirements. Our team can custom blend filter media based on factors such as odours, contaminants, chemical compounds, air flow restrictions, desired efficiency levels, and budget constraints.

Air Box 4×8 media is activated carbon granules with a well-developed pore structure allowing for a wide range of
absorbent retention. Air Box 4×8 has excellent absorption of organic contaminants and is particularly well suited for precious metal recovery.

Air Box 448 media consists of a 50:50 blend of Air Box 4 media and Air Box 4X8 media. Air Box 448 offers excellent filtration of acidic gases and organic substances when space is limited, and a wide range of filtration is needed.

Air Box 4 media consists of porous activated alumina spheres that have been impregnated with a minimum of 4% potassium permanganate. Air Box 4 reduces corrosion caused by acidic gasses via an oxidation reaction to inactive solids
