MERV 8 Air Filter, Reusable ABS Plastic Frame, 7 Pack Replaceable Filter Media

Product Description: The Importance of MERV Ratings and Filter Thickness

MERV, which stands for Minimum Efficiency Reporting Value, is an industry-standard rating system used to evaluate the effectiveness of air filters. While this concept may be challenging for consumers to grasp, OlitAir has developed an easy-to-use application-based naming system to help you choose the filter that best suits your needs.

Factors such as pets, odors, and smoking can significantly impact the quality of your indoor air. OlitAir Air Filters offers a wide range of air filters designed to help you breathe easier and select the correct filter based on your specific requirements.

Ensuring the proper fit of your filter within your HVAC system is crucial. This 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:

A. Nominal Size vs. Actual Size The nominal size is a shorthand number rounded to the nearest whole or half inch, typically in a larger font (e.g., 20 x 20 x 1). The actual size, on the other hand, is an exact measurement, usually 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.

B. 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, width, and 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 choose the correct filter size, you can ensure that your HVAC system is operating at optimal efficiency and that you are breathing cleaner, healthier air. OlitAir is committed to providing you with the tools and information you need to make an informed decision about your air filtration needs.
