An Inside Look at ASHRAE 52.2
An ASHRAE 52.2 test report provides a wealth of useful information beyond a simple MERV rating. We’ll review various sections of a sample report and provide insight on what to look for when conducting a filter evaluation.
Electret-Charged Media: Harnessing a Fundamental Force of Nature for Superior IAQ.
Electret Charging Explained: They’re probably better known than they are understood. First observed by the ancient Greeks, and available commercially since 1930 with the introduction of the Hansen resin-wool filter, electrets today are found in a variety of filtration applications.
Energy Efficient IAQ and the Classroom
Evidence continues to mount that Indoor Air Quality (IAQ) directly impacts student academic performance and health. Unfortunately, IAQ is reported to be unsatisfactory in about one in five public schools in the United States, while ventilation is reported as unsatisfactory in about one-quarter of public schools.
Exceptional Workplaces Start with Healthy Workplaces
Whether our workplace is an office building, school, hospital, retail setting or some other type of facility, our collective hope and expectation as we walk through the door each day is that the place we spend so much of our time and expend so much of our energy will be a healthy place.
Energy Audits Help Control Rising Energy Costs
An energy audit is a term used to describe a broad spectrum of energy studies, ranging from a quick walk-through of a facility to identify major problem areas, to a comprehensive analysis of the implications of alternative energy efficiency measures sufficient to satisfy the financial criteria of sophisticated investors.
Self-Supported Pleats: What You Need to Know
Self-supported pleat filters were developed in the late 1990s to replace wire-supported HVAC pleat filters in the North American market. Today, they are available from a limited number of national manufacturers at MERV 6, 7 and 8 performance levels.
Bypass Air—What You Don’t Filter Can Hurt You
Effective air filtration provides a primary defense for building occupants and HVAC equipment against airborne pollutants that can cause health problems as well as HVAC system maintenance problems. That’s why selecting the right filter and proper HVAC maintenance are so critical.

Air Filtration: Balanced Approach Gives High Filtration and Energy Efficiencies
An effective air filtration strategy provides a prime defence for building occupants and HVAC equipment against pollutants generated within a building as well as pollutants from air drawn into a building from the HVAC system.
Evaluating Filtration Efficiency
Air filters perform an important function in commercial and institutional facilities. Because indoor air is typically two to five times more polluted than outdoor air, air filters are needed to remove respirable particles such as microorganisms, dust and allergens from the breathing air.
Not All Filters are Created Equal
While one may think of a building’s HVAC system as a whole, there is one component of HVAC systems with a pronounced effect on a building’s ability to maintain a healthier indoor environment while keeping energy costs low: the air filtration system.
Beyond MERV: Selecting Air Filters for Optimal IAQ Performance
Ideally, illness triggers such as microorganisms, dust and allergens should be eliminated or significantly reduced by the facility’s HVAC system. The key component to reducing these triggers is effective air filtration, which provides the primary defense against air pollutants generated within a building as well as pollutants from air drawn into the building by its HVAC system.
