How Long Do Merv Filters Last? A Comprehensive Guide

When it comes to maintaining a healthy and comfortable home, one of the most important things to consider is the quality of the air you breathe. To ensure that your air is clean and free of dust, dirt, and other allergens, it's important to regularly replace your air filters. But how often should you replace them?The answer depends on the type of filter you have. Generally speaking, basic MERV 8 filters should be replaced every 3-4 months, MERV 10 and 11 filters should be replaced every 6 months, and MERV 16 filters should be replaced annually.

However, if you have a fiberglass filter, experts recommend changing it every 30 days. For more specific recommendations, here's a breakdown of how often different types of filters should be replaced:

• One-inch oven filter: Replace every 1-3 months
• Three- to four-inch filter: Replace every 6-9 months
• Five- to six-inch coarse-grained filter: Replace every 9-12 months

It's important to note that these are just general guidelines. Depending on your specific needs and the environment in which you live, you may need to replace your filter more or less often. For example, if you live in an area with high levels of air pollution or if you have pets in your home, you may need to replace your filter more frequently. In addition to filtering particles filtered by MERV 8 and 11, MERV 13 filters can also filter out kitchen smoke, smog, and virus carriers. If you have a MERV 13 filter, it's recommended that you replace it at least every 90 days. By making sure your filters are changed when needed, you can enjoy a heating and cooling system that will perform better and cleaner air that is easier to breathe.

So make sure to keep track of when your filters need to be replaced and don't forget to change them when the time comes!.
