Which Merv Rating is Best for Your Home?

When it comes to selecting the best air filter for your home, the Merv rating is an important factor to consider. According to ASHRAE, the best rating for residential HVAC systems is Merv 13. However, this may not be the best option for your home as a higher Merv index often means lower airflow, which can cause the system to work harder and use more energy. A MERV rating of between 6 and 13 generally meets the needs of most residences, offering a good balance between air filtration, airflow and affordability.If you select an air filter with a MERV 13 rating, it can last up to six months before you need to replace it.

A Merv 8 is considered a superior filtration compared to air filters with a lower MERV rating. In many cases, a Merv 8 air filter is more than adequate. However, if you are concerned about outdoor air pollution, family members with respiratory problems, or pets in the house, then a higher MERV rating might be a good idea.MERV ratings are a rating system designed by ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) to inform the effectiveness of air filters. The lowest efficiency with minimal filtration is MERV 1 while 16 offers the highest efficiency and filtration.

Our recommended MERV rating for oven filters ranges from 6 to 8 to strike a great balance between maximum oven efficiency and home comfort.Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow. Meanwhile, air filters with a MERV 14 rating or higher are designed for commercial HVAC systems that can handle the coarsest filter material. If your family has allergy problems or severe respiratory problems, such as asthma, you may want to invest in filters with higher MERV ratings.The best MERV rating for your home will depend on what you want to filter and the amount of airflow your HVAC system needs to operate. Remember, there are always other options available to improve indoor air quality if your system can't handle the MERV ratings you need.

Ultimately, it's important to select an air filter that meets your needs without putting additional pressure on your HVAC system.
