A few weeks ago, we explained what a micron is and why it’s important. Now we are going to examine what a MERV rating is and why it matters. Let’s start off with what the word MERV means. MERV is an acronym that stands for Minimum Efficiency Reporting Value. MERV is the standard that rates the overall performance of air filters and was created by The American Society of … [Read more...] about What does MERV mean?
Do you know what size filter you need, but have no idea what MERV rating you need? First of all, we should establish what a MERV rating actually means. MERV ratings are based on three composite, average removal efficiency points for particles it catches from the air. MERV numbers range from 1 (very low) to 16 (very high). Here’s an easy way to remember it: the higher the … [Read more...] about Which MERV Rating Should I Choose?
Did you know that you most likely have more airborne particulates in your air than the standard 1" air filter can handle? It is true that air filters work wonders when it comes to capturing many of the particulates that circle in the air you breathe. It is also true that getting a filter that is more than the 1" standard can totally protect you from the harmful particulates in … [Read more...] about Upgrade From Your Standard 1 Inch Filter
Air filters remove airborne allergens and pollutants such as dust, mold, pollen, pet dander and bacteria from your indoor air. There is a vast array of air filters with different levels of measurement for determining the concentration of different particle sizes, usually by weight or count. This measurement of performance for air filters is called Minimum Efficiency Reporting … [Read more...] about Is The MERV Rating for An Air Filter Important for Allergies?
Without the proper precaution, schools can be a breeding ground for illness among the millions of children that attend each year. It is perhaps with this in mind that Greenguard Environmental Institute recently launched an interactive school indoor air quality tour on its website. The tour takes place inside a graphic representation of a school with cartoon-esque teacher and … [Read more...] about Greenguard School IAQ Tour
