While it’s true that higher MERV ratings indicate greater filter efficiency, it’s also important to consider the potential drawbacks of using a filter with a high rating. Filters with MERV ratings of 14 or higher may capture smaller particles, but they can also cause significant airflow restriction and put additional strain on the HVAC system, leading to reduced system performance and higher energy bills.
That’s why we recommend pleated filters with a MERV rating no greater than 10 for most residential applications. These filters strike a balance between efficiency and airflow, capturing a range of particle sizes without significantly restricting airflow or putting excessive strain on the system. In fact, using a filter with a MERV rating that’s too high can be just as detrimental to system performance as using a filter with a low rating.
Of course, every home and HVAC system is different, so it’s important to consider a range of factors when selecting the right filter. For example, households with pets, smokers, or residents with allergies or respiratory issues may benefit from a higher-rated filter or more frequent filter changes. It’s also important to consult with a qualified HVAC professional to ensure that your system can handle the increased airflow resistance of a higher-rated filter.
In summary, pleated filters with a MERV rating of 8-10 provide effective filtration without significantly restricting airflow or putting undue strain on the HVAC system. However, it’s important to consider individual needs and system specifications when selecting the right filter for your home.
