Product Description: Importance of MERV Ratings and Filter Thickness

Understanding the significance of MERV ratings and filter thickness can be crucial in maintaining healthy indoor air quality. MERV, which stands for Minimum Efficiency Reporting Value, is the industry-standard metric used to evaluate the efficiency of air filters. To simplify this complex concept for consumers, we have developed an intuitive application-based naming system that makes it easier for you to select the most suitable filter for your specific needs.

Factors such as pets, odors, and smoking can significantly impact the air quality within your home, which is why OlitAir Air Filters offers a diverse selection of filters to cater to various requirements. Whether you need to address pet dander, eliminate odors, or reduce the impact of tobacco smoke, we have the right filter for you.

An essential aspect of ensuring optimal performance of your HVAC system is selecting a filter that fits perfectly. This involves not only ensuring the right length and width but also considering the thickness of the filter. Standard air filters typically range from 1 to 2 inches in thickness, while media filters are generally 3 to 5 inches thick. To determine the correct size for your air filter, it's best to use a measuring tape, as the dimensions of your current filter are usually printed on the frame.

Choosing the Correct Filter Size

A. Nominal Size vs. Actual Size

The nominal size is a rounded number (to the nearest whole or half inch), typically displayed in a larger font (e.g., 20 x 20 x 1). In contrast, the actual size represents the precise measurements of the filter and is usually indicated in a smaller font (e.g., 19.75 x 19.75 x 0.75). It's important to note that all filters have both nominal and actual sizes.

B. Measuring Your Air Filters

If the dimensions of your current air filter are not listed on the frame, you can use a tape measure to determine the length, width, and depth, and then round these measurements up to the nearest inch to find the corresponding nominal size. This will make it easier for you to locate the right filter when searching online.

In conclusion, understanding MERV ratings and filter thickness is essential for maintaining clean and healthy indoor air quality. By choosing the correct filter size and type, you can ensure optimal performance of your HVAC system and enjoy fresher, cleaner air in your home. With OlitAir Air Filters, you can breathe easier and confidently select the right filter for your specific needs.
