With the introduction of ISO 16890 to the world (only the United States is left to adpot it) there has been a lot more talk and research about the relationship between air filters and air quality. This discussion has been happening before, but with little emphasis on...
An air filter frame is just a bent up piece of sheet metal isn't it? For many manufacturers the answer is yes, but for the end user that wants to ensure a proper fit and minimal to no bypass of air then the answer is...
Secondary filters are not only expensive, but they also put a big energy drag on an HVAC system because of their increased resistance to airflow. But that energy drag can be greatly reduced by simply switching air filter styles/makes! Take a look at the following...

Most of us don't give much thought to our MERV-8 or MERV-10 prefilters, most of still change them on a schedule every 3-4 months, but these filters do impact a building's energy consumption in a big way. So how do different styles of air filters...
Ever wonder how much energy is required to overcome the restriction of the air filters in your HVAC system? And how different styles of air filters can increase or reduce this energy drag? Take a look at the following energy use demonstration to see...

Oh MERV, if there were any clearer reason why you are going to be replaced by ISO 16890, it is the confusion of 95% air filters. A still common specification for final filters in hospitals the 95% filter could refer to MERV 14, MERV 15, or...
One of the more common requests we get is to do a cross between different filter test methods. For years it was a 52.1 to 52.2 cross, then when Europe adopted EN779 charts crossing those two came about now with the adoption and publication of ISO...
