Importance of MERV Ratings and Filter Thickness in Product Description

Understanding MERV Ratings and Filter Thickness

MERV, which stands for Minimum Efficiency Reporting Value, is an industry-standard used to rate a filter's effectiveness. We realize that this concept may be challenging for consumers to understand, so we have developed a user-friendly application-based naming system to assist you in selecting the most suitable filter for your needs.

Factors Affecting Indoor Air Quality

Household pets, lingering odors, and smoking can all have a significant impact on the quality of the air indoors. OlitAir Air Filters offers a wide range of air filters to help improve the air you breathe, allowing you to choose the right filter based on your specific requirements.

Importance of Filter Size

Ensuring that your filter fits correctly in your HVAC system involves not only verifying the right 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. 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 rounded shorthand number, often in a larger font (e.g., 20 x 20 x 1), while the actual size is a precise measurement typically in a smaller font, portraying the filter's exact 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 dimensions listed on the frame, use a tape measure to record the length x width x depth to determine the actual size. Round these measurements up to the nearest inch to find a corresponding nominal size, which will make it easier to locate when searching online.

Choosing the right air filter size is crucial for ensuring the effectiveness of your HVAC system and indoor air quality. Trust OlitAir Air Filters to provide the expertise and options you need for a healthier living environment.
