Replacing your air filter might be the easiest way to maintain a healthy air quality in your home. When a filter is dirty it will restrict air flow and cause your system to run inefficient. While an inefficient system will not only raise the price of your energy bill but could cause health issues. A good rule of thumb is to replace your air filter every month on the 1st of each month as a simple reminder. There are many brands out there to choose from along with different levels of filtration.
