These HEPA filters are manufactured using a polypropylene nonwoven media that has been electrostatically charged. This media supplies the same filtration properties as the typical glass media, but with a much more efficient air flow through the filter. This high quailty air filtration is accomplished with an initial pressure drop of only 0.25 - 0.30 inches of water gauge (wg), compared to the initial pressure drop of 1.0 inch water gauge (wg) for other current filters. Thus, these new filters result in about one fourth of the pressure drop that results from the use of current standard HEPA filter technology.

In addition, they provide enhanced dust collection characteristics, allowing for a longer life cycle without substantially increasing the pressure resistance.

Commercial Benefits:

• Increased system efficiency from clean components
• Increased system life
• Lower maintenance and housekeeping costs
• Avoidance of product failure
• Lower energy costs
• Lower health risks and costs
• Increased productivity and reduced absenteeism
• Decreased efficiency losses from the insulating effect of dirt build-up on heat transfer surfaces, such as HVAC coils.
