Product Description: Importance of MERV Ratings and Filter Thickness

Understanding MERV Ratings and Their Significance MERV, short for Minimum Efficiency Reporting Value, is an industry-standard used to rate the efficacy of air filters. Although this technical term may be challenging for some consumers to grasp, OlitAir has developed an easy-to-use, application-based naming system to help you select the filter that best suits your needs.

Factors Affecting Indoor Air Quality Pets, odors, and smoking can significantly impact the quality of your indoor air. To address these concerns, OlitAir Air Filters offers a wide variety of air filters designed to help you breathe easier and choose the correct filter based on your specific requirements.

Ensuring Proper Filter Fit Proper filter fit in 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. To determine the size of your air filter, the best approach is to use a measuring tape, as the dimensions of your current filter are likely printed on the frame.

Nominal Size vs. Actual Size When selecting an air filter, it's important to understand the difference between nominal size and actual size. The nominal size is a shorthand number rounded to the nearest whole or half inch, usually displayed in a larger font (e.g., 20 x 20 x 1). In contrast, the actual size is an exact measurement, typically shown in smaller font, that represents 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 the dimensions listed on the frame, you can 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 determine the corresponding nominal size, which will be easier to locate when searching online.

By understanding the importance of MERV ratings, filter thickness, and proper filter size, you can ensure that you select the most effective air filter for your HVAC system, ultimately improving the quality of the air you breathe in your home or office.
