Air filters come in various specifications: materials, densities, structures, etc. All of these contribute to the quality a filter brings in capturing impurities from the passing air. To better understand the quality of each product, you need to take a look at its MERV level.
MERV stands for Minimum Efficiency Reporting Values. This rating represents how capable a filter is in capturing particles of 0.3 to 10 microns. The MERV air filter system was developed from the ASHRAE test method. The higher the rating means the more impurities the filter can block.
A lower MERV rating doesn’t mean the filters are useless because each efficiency level has allotments. On the other hand, getting an extremely high MERV air filter could be a waste of money.
To provide a little more perspective, here are what air filters can do on different levels:
These filters are commonly used as pre-filters in commercial buildings. They can also work for residential furnaces and window ACs in preventing debris from damaging the inner system, but not enough to improve indoor air quality.
Air filters in this category are most commonly used as pre-filters or final filters in commercial and residential buildings. They can also be sufficient in the industrial workplace and paint booth inlets.
These filters are commonly used as pre-filters or final filters in healthcare facilities, middle to high-class commercial buildings, and high-class residential units.
These filters are typically used as final filters in healthcare facilities, high-class commercial buildings, and smoking lounges.
These filters are used in buildings with radioactive or carcinogen toxins. Pharmaceutical facilities and orthopedic surgery rooms may also benefit from this level of MERV air filters.
Looking into the MERV air filter is essential when browsing for filters to install on your HVAC system. By understanding how the parameters work, you will be able to determine which filter is best to buy. More than that, you will better understand what could happen if you choose to cut corners by buying a cheaper one.
