Everyone wants to reduce energy costs. Not only is it good for the household budget, but it also will help the environment by reducing your carbon footprint.
Since the majority of home energy usage is spent on heating, it is a good place to reduce costs. A simple way to save money on heating is by replacing the air filter in your furnace regularly.
How Changing Your Air Filter Saves You Money
The purpose of an air filter is to keep dirt and debris out of the furnace. Over time, these particles build up in the filter. That makes it hard for air to get through. The furnace fan needs to work harder to get the needed air, which in turn uses more energy. Changing the filter when necessary allows the air to flow more efficiently, saving you money on heating costs.
Replacing your filters saves you money in more ways than one. When you run a furnace with a clogged filter, it also causes excess wear on the furnace fan. In addition, if there isn’t enough air getting through, the furnace can overheat. That can lead to serious damage and costly repairs.
How Often You Should Change the Air Filter
There are different types of air filters, and each type has a different life span. Some types of filters need to be changed every 30 days. Other types only need replacing every 90 days. Washable air filters can last a year or longer, but they usually need to be cleaned monthly. At AirFilterBuy, we always display clearly the time frame in which a filter is supposed to be replaced. As a rule of thumb, the typical AFB branded 1", 2", and 4" filters are designed to last 3 months. Ourwhole house replacement filters, generally the 5" and 6" thick filters, are designed to last 6 months due to the amount of pleated media that they contain.
There are several factors that will influence how long it takes for your filter to become clogged. The amount of time you run your furnace each day will impact how long you can go between changes. During the warmer months, your air filter will probably need to be changed less often than it will when it is running every day. However, this obviously depends greatly on your geographical location!
Increased amounts of contaminants in the air will cause your filter to become dirty more quickly. If you have a lot of pets, live in a high-pollen area, or have smokers in the home, your filter will need to be changed more often.
As a general rule, you should check the filter monthly to see if it needs to be changed, even if you have a 90-day filter. This will allow you to determine if your filter needs to be changed more often.
The Bottom Line
Replacing your air filter every one to three months may seem like an inconvenience or unnecessary expense, but is well worth it. You will save money on your home energy bills, reduce your carbon footprint, and prevent costly, unnecessary damage to your furnace.
