How to Easily Change Your Merv 11 Filter

If you want to keep your HVAC system running smoothly, it's important to regularly replace your air filter. A deactivated filter prevents air from entering and carrying dust and sand into the system. To change your Merv 11 filter, you'll need to open the ventilation grille and remove the used filter. The filter size, called the “nominal” size, is printed on the side of the existing filter.

This is the measurement you'll need to reorder a new one.It's important to note that the nominal size will be different from the actual size. As a general rule, an air filter is ½ smaller than its stated size. For example, a 20x20x1 filter actually measures 19.5x19.5 inches. To ensure that you don't forget about replacing your oven filter, it's a good idea to add a reminder to your calendar or phone.

You can also set up periodic shipping with FilterBuy and get a 5% discount on your orders. Studies have shown that maintaining a clean air filter in your HVAC system can reduce electricity bills by up to 15%. During periods of heavy use, a clogged air filter can substantially increase your electricity bill, so it's definitely beneficial for you to keep up with your oven filter replacement.
