Importance of MERV Ratings and Filter Thickness in Choosing the Right Air Filter

Understanding the significance of MERV ratings and filter thickness is crucial in selecting an effective air filter for your needs. MERV, which stands for Minimum Efficiency Reporting Value, is an industry-standard measure of a filter's efficiency. While this concept may be challenging for consumers to comprehend, we have developed a user-friendly application-based naming system to simplify the process and help you choose the right filter for your specific requirements.

The quality of indoor air can be significantly impacted by pets, odors, and smoking. OlitAir Air Filters offers a diverse range of air filters designed to help you breathe easier. It is important to select the correct filter that addresses your specific concerns.

Part of ensuring that your filter is suitable for your HVAC system involves considering not only the length and width, but also the thickness of the filter. Standard air filters are typically 1-2 inches thick, while media filters are generally 3-5 inches thick. To determine the size of your air filter, use a measuring tape as the dimensions of your current filter are likely printed on the frame.

Choosing the Right Filter Size

A. Nominal Size vs. Actual Size

The nominal size is a rounded shorthand number, often in a larger font (e.g. 20 x 20 x 1), while the actual size is the precise measurement of the filter, usually in a smaller font (e.g. 19.75 x 19.75 x 0.75). It is important to take both sizes into account when selecting a filter.

B. Measuring Your Air Filters

If the dimensions of your current air filter are not listed on the frame, use a tape measure to determine the length, width, and depth to find the actual size. Then, round these measurements up to the nearest inch to find the corresponding nominal size, which will make it easier to locate when shopping online.

Understanding the importance of MERV ratings and filter thickness is essential in selecting the right air filter for your home. With OlitAir Air Filters, we make this process easier for you so that you can breathe cleaner and healthier air.
