When it comes to air filtration, the MERV and FPR ratings are essential for finding the right filter for your home. The MERV rating is used to determine the filter's resistance, with higher ratings indicating a stronger filter. The FPR rating is used to communicate information about the filter's performance. Both ratings use numerical values, and some filters have both an FPR and a MERV rating.
Air filters with a lower MERV rating, such as MERV 1 to MERV 4, are not great at trapping small particles. In cases where an air conditioning system cannot withstand a MERV 13 rating or higher due to airflow problems in older units, a MERV 11 air filter can offer additional benefits and capture a wider range of particles that would pass through a MERV 8 filter. It is important to note that the filters will perform lower than their MERV rating if the speed is higher than the tested speed and will exceed their MERV rating if the speed is much lower. Therefore, it is important to consider both ratings when selecting an air filter for your home. When choosing an air filter, it is important to consider the environmental risks associated with using filters with MERV and FPR ratings.
Air filters with higher ratings can trap more particles, but they can also reduce airflow in your home. This can lead to increased energy costs as your HVAC system has to work harder to maintain the desired temperature. Additionally, air filters with higher ratings can cause more dust buildup in your home, which can lead to respiratory issues for those with allergies or asthma. It is also important to consider how often you need to replace your air filter. Air filters with higher ratings need to be replaced more often than those with lower ratings.
This can be costly over time and can also lead to increased waste in landfills. When selecting an air filter for your home, it is important to consider both the environmental risks and benefits associated with using filters with MERV and FPR ratings. Consider the size of your home, the type of air conditioning system you have, and how often you need to replace your air filter before making a decision.
