Learn about the differences between MERV 11 and MERV 13 filters and find out which one is better for your home.

MERV 13 vs. MERV 11: Which Filter is Better for Your Home?

When it comes to air filters, MERV 11 and MERV 13 are two of the most popular options. But which one is better for your home? To answer this question, it's important to understand what a MERV rating is and how it affects the efficiency of a filter. A MERV rating is a measure of a filter's ability to capture particles of different sizes. The higher the MERV rating, the more particles the filter can capture.

MERV 11 filters have a particle arrest of around 90%, while MERV 13 filters have a particle arrest of around 98%. This means that MERV 13 filters are significantly more efficient than MERV 11 filters. However, it's important to note that using the highest MERV rated filter in your home can restrict airflow and make it difficult for your HVAC system to operate properly. Home Energy published an article by Dave Springer of Davis Energy Group which found that raising just two or three MERV rating levels can be a wise decision that improves air quality without putting too much strain on the system.

When it comes to cost, MERV 11 filters should be replaced every 1 to 3 months, depending on the season and the intensity of work of your HVAC system. On the other hand, MERV 13 filters should be replaced every 1 to 2 months, especially if the oven or air controller is used frequently. In conclusion, if you're looking for maximum efficiency and improved air quality, then a MERV 13 filter is likely your best option. However, if you're looking for a more cost-effective solution, then a MERV 11 filter may be more suitable for your needs.
