MERV 8 Air Filter, 7 Pack Replaceable Filter Media

Why MERV Ratings and Filter Thickness Are Important

The Minimum Efficiency Reporting Value (MERV) is an industry-standard used to rate a filter's efficacy. We understand that this may be challenging for consumers to comprehend, which is why 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 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 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.

In summary, MERV ratings and filter thickness are crucial factors to consider when choosing an air filter for your HVAC system. The MERV rating indicates the filter's efficiency in capturing airborne particles, while the filter thickness determines its compatibility with your system. By understanding the difference between nominal and actual sizes, and properly measuring your current filter, you can ensure you select the correct replacement that will effectively improve your indoor air quality.
