When it comes to air filters, the MERV rating is an important factor to consider. MERV stands for Minimum Efficiency Reporting Value and it is used to measure the effectiveness of air filters. A MERV 8 air filter is designed to capture particles between 3 and 10 microns in size, while a MERV 11 air filter can capture particles between 1 and 12 microns in size. Based on these characteristics, a MERV 8 is considered superior filtration compared to air filters with a lower MERV rating.
But is filtration enough? In many cases, a MERV 8 air filter is more than adequate. However, if you're concerned about outdoor air pollution, family members with respiratory problems, or the presence of pets at home, then opting for a higher MERV rating might be a good idea. If you're new to selecting air filters, you might still not be sure what's the best option, despite the detailed explanation above. When considering the airflow capabilities of the MERV 8 versus the MERV 11, raising just three MERV rating levels can be a smart decision to turn air into an air purifier or a detrimental option for the entire air conditioning system. When buying an air filter, most people wonder if the MERV 8 is a good enough air filter for their homes.
If you're concerned about the effects of breathing fine air particles, that's another reason to choose a MERV 11 air filter instead of a MERV 8 air filter. The classification is based on a test method developed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) and is useful for determining which air filter will work best for your heating and air conditioning system and for indoor air quality objectives. However, the EPA notes that high-efficiency particulate air filters (HEPA filters) are theoretically capable of eliminating at least 99.97% of mold, dust, pollen, bacteria and airborne particles with a size of 0.3 microns in size. MERV 11 air filters are a bit more expensive than a standard filter, but it's usually worth paying a few more dollars per filter. Choosing the perfect air filter is incredibly important because choosing one that is too high or too low can be hazardous to your health and your home. If someone has an allergy or respiratory problem, opt for a MERV 11 air filter or even a MERV 13 air filter. It's best to use a category 13 MERV filter to protect yourself from the bacteria that spread the virus, but you should also consider adding air quality solutions to your home.
If you're looking for a common household air filter to maintain efficient airflow and better air system performance, then the MERV 8 is the filter you need. One thing to keep in mind is that a MERV 11 air filter may need to be changed a little more frequently than a MERV 8 air filter. Although in most cases, MERV 8 furnace filters are better for your home, the air filter that best suits your home is chosen based on the state of your home at the time. Generally speaking, everything underneath a MERV 13 air filter should provide very efficient air purification in a home without affecting airflow. The air filter must be changed regularly to ensure that the HVAC components in your home are in perfect condition.
