There is a newly published guideline related to residential IAQ and how air filters play a role in protecting occupants. ASHRAE Guideline 24-2015 states PM2.5 “may be one of the most significant indoor airborne contaminants in terms of chronic health impact in residences.” The article states MERV 13 or higher is (more…)

Have you ever wondered what MERV stands for? MERV stands for Minimum Efficiency Reporting Value. It was developed by ASHRAE as a way to compare different filters. The standard has changed since it’s inception, and it’s important to stay up to date on what is changing. The guide below shows the new efficiency (more…)

Have you ever wondered what is in the air we breathe? Studies have been done to characterize particle sizes of known airborne contaminants. Some contaminants cause reactions to the body while others do not. By knowing what is around us, we can determine how to properly remove it with filtration. (more…)

Are you certain that the HVAC air filters you’ve specified are the right ones for your facility? Selecting the right air filters doesn’t have to be complicated, but it does require attention to details including submicron particle capture efficiency, energy consumption implications and more. (more…)
