Summary

Wildfires have emerged from a localized nuisance to an annual problem that affects millions. They generate a wide range of gas phase and particulate contaminants. The smoke composition varies based on the heat and relative completeness of the combustion and the great variety of material that can burn in the path of a wildfire. Wildfire smoke changes rapidly and significantly with time and distance, as most gas phase contaminants disperse and l

Abstract: This study determined the effectiveness of components of a germicidal air-cleaning system involving filtration, electrostatic polarization, and UV light on the reduction of airborne bacteria and molds. The filter alone, filter and electrostatic polarization combined, and the filter, electrostatic polarization, and UV light were found to be effective (P < 0.05) in reducing a given concentration of M. luteus and S. marcescens by 90 to 92%. The same components were

Non-ionizing  polarized media is an IAQ technology finding broader market uses. It applies an active electric field to cap tore airborne particles, changing the way particles, behave in the air. In smaller residential equipment, this allows an electronic air cleaner (EAC) to operate efficiently within a space only 1 inch wide - the same sp-ace as a disposable filter. In larger commercial systems, it can mean high levels of air quality with reduced operating costs.

This year we are very pleased to celebrate the thirtieth anniversary of the first one-inch polarized-media electronic air cleaner. It was thirty years ago that the first polarized-media electronic air cleaner, produced under our “Dynamic Air Cleaner” brand, was introduced.

As with many high-efficiency filtration products, polarized media has its roots in industrial applications. Although the first electrically enhanced air filters date back to 1930, it wasn’t until 1

George Washington once said, “We should not look back unless it is to derive useful lessons from past errors, and for the purpose of profiting by dearly bought experience.” Since it has been more than five years of occupancy since ASHRAE Headquarters was renovated, this is a good time to revisit the details of the renovation project, the successes, and lessons learned. Future articles will delve deeper into the performance of the various building systems, satisfaction of building

Challenge: Optimize Indoor Air Quality and reduce maintenance costs. The owner wanted clean indoor air to protect the library contents in an urban environment and wanted to replace outdated electronic air cleaners and rolled media filters that were installed whe

Abstract:
Building owners and occupants expect more from their buildings today – both better indoor air quality (IAQ) and less energy consumption. Many facilities strive to design and commission a ‘smart building’ – one that is healthy, environmentally conscious and operating in the most efficient way possible. However, maintaining optimum IAQ often seems to be in conflict with minimizing operating and energy costs. Conventional wisdom says the be
