How Can I Choose the Right Furnace Air Filter for My Home?
There are a few things to consider when it comes to choosing the right furnace air filter for your home; the size and MERV rating. Air furnace filters can vary in size, depending on your heating system.
If your heating system has an existing filter, you can check the frame for a printed size. Alternatively, you can remove the filter and measure the length, width, and height of the filter. Once you’ve determined the right size filter, you can dive into the finer details, such as the MERV rating.
The higher the MERV rating, the smaller the particles the filter can trap. As a result, it can output even cleaner air. While a higher MERV rating can mean cleaner air, it can also slow airflow.
A lower MERV rating on the other hand can be more energy efficient, but may require replacement more frequently. If you have allergies, opting for a MERV rating 8 may be most appropriate.
