MERV 8 Air Filter, 7 Pack Replaceable Filter Media

The Importance of MERV Ratings and Filter Thickness

MERV, which stands for Minimum Efficiency Reporting Value, is an industry-standard used to rate a filter's effectiveness. We understand that this terminology may be difficult for consumers to grasp, so we have developed an easy-to-use application-based naming system to help you choose the filter that suits your needs.

Pets, odors, and smoking can all significantly impact the quality of your indoor air. OlitAir Air Filters offers a wide variety of air filters to help you breathe easier and select the correct filter based on your specific requirements.

Ensuring that your filter fits properly in your HVAC system involves verifying not only the right length and width but also the thickness of your filter. Most standard air filters are 1-2 inches thick, while media filters are generally 3-5 inches thick. The best way to measure your air filter size is to use a measuring tape, as the dimensions of your current filter are likely printed on the frame.

Choosing the Correct Filter Size

Nominal Size vs. Actual Size: The nominal size is a shorthand number rounded to the nearest whole or half inch, normally in a larger font (e.g., 20 x 20 x 1). In contrast, the actual size is an exact measurement, normally in a smaller font, that depicts the filter's precise dimensions (e.g., 19.75 x 19.75 x 0.75). All filters have both nominal and actual sizes.

Measuring Your Air Filters: If your current air filter does not have a dimension listed on the frame, use a tape measure to record the length x width x depth to find the actual size. Then, round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online.

By understanding the importance of MERV ratings and filter thickness, as well as how to properly measure and choose the correct filter size, you can ensure that your HVAC system is operating at its best, providing you with cleaner, healthier indoor air. Our easy-to-use application-based naming system makes it simple to select the right filter for your needs, allowing you to breathe easier and maintain a comfortable living environment.
