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

Why are MERV ratings and filter thickness important? It's because MERV, which stands for Minimum Efficiency Reporting Value, is the industry standard used to rate the effectiveness of filters. We understand that this might be confusing for consumers, so we have developed a user-friendly application-based naming system to help you choose the right filter for your needs.

Pets, odors, and smoking can all have a significant impact on the quality of your indoor air. That's why OlitAir Air Filters offers a wide range of filters to help you breathe easier. We can assist you in selecting the correct filter based on your specific requirements.

Ensuring that your filter fits properly in your HVAC system is crucial. This involves verifying not only the length and width, but also the thickness of the filter. Standard air filters are usually 1-2 inches thick, while media filters are typically 3-5 inches thick. To determine the size of your air filter, use a measuring tape. The dimensions of your current filter are likely printed on the frame.

When it comes to choosing the correct filter size, there are two considerations: nominal size and actual size. The nominal size is a rounded number, often displayed in a larger font, such as 20 x 20 x 1. On the other hand, the actual size is the precise measurement, usually shown in a smaller font, like 19.75 x 19.75 x 0.75. All filters have both sizes listed.

If your current filter doesn't have dimensions listed on the frame, use a tape measure to record the length, width, and depth to find the actual size. Then, round up these measurements to the nearest inch to determine the corresponding nominal size. This will make it easier to locate when searching online.
