Filtration Effectiveness and Ratings: Understanding the MERV Scale

The Minimum Efficiency Reporting Value (MERV) rating is a standardized scale that measures a filter's ability to capture airborne particles, ranging from 1 to 20. This scale provides a clear understanding of a filter's performance, allowing you to select the optimal level of protection for your specific needs.

Choosing the Correct Filter Size When selecting an air filter, it's important to consider both the nominal size (rounded to the nearest inch) and the actual size (precise measurements) to ensure a proper fit for your HVAC system. Measuring your current filter and rounding up to the nearest inch will help you find the right replacement.

Why Change Your Air Filter? Regularly replacing your air filter is crucial for maintaining a healthy lifestyle and ensuring your HVAC system operates efficiently. Dirty filters can lead to various issues, including increased energy costs, system malfunctions, and the development of respiratory ailments.
