Commercial services provide many benefits, including helping figure out which air filter is best.
Having clean indoor air sometimes requires the extra help of commercial services. Outside assistance may be necessary because choosing the right air filter is sometimes a complex process. There are several things to consider when balancing energy usage with having the cleanest indoor air possible. The following is a basic overview of choosing an indoor air filter.
The primary method of choosing an indoor air filter is to look at its minimum efficiency reporting value (MERV) rating. This is a measure of how well the air filter will remove air particles from the air. The lower the MERV rating, the less effective it will be in eliminating tiny particles. The higher the MERV rating, the more efficient the filter will be in cleaning the smallest particles.
To further clarify, a MERV rating does not measure the "quality" of an air filter. Rather, it helps explain what size of particle the air filter can catch, and therefore remove, from the air.
An air filter with a MERV rating below five means the air filter can only effectively remove particles from the air that are easily visible, such as dust, small fibers, hair and pollen. An air filter with a MERV rating between five and 10 means the filter can remove even smaller particles, such as pet dander and mold spores. An air filter with a MERV rating between 10 and 15 means it can remove very fine dust particles, such as flour and smoke. Air filters with MERV ratings above 15 can remove the tiniest of particles, such as bacteria and viruses.
The typical home or office will not need an air filter with a MERV rating above 15. In fact, the typical office probably won’t need an air filter with a MERV rating above a 10.
If office workers have special respiratory needs, getting an air filter with the highest MERV rating may be helpful. But business owners need to make sure the HVAC system can handle the air filter. The smaller the particles an air filter can remove from the air, the harder the HVAC system will work to push air through the filter.
