The Importance of Air Filters and How They Function
While heating and cooling are the main functions of any HVAC unit, filtering the air is essential for the household's health and the machine's efficiency. Air filters are essential for good indoor air quality and for keeping dust and other particulate matter out of the working parts of the heating and cooling unit.
The flip side is that filters can cause issues if they are not replaced often enough. In this article, HVAC professionals discuss what filters do, when they need to be replaced, and the advantages of frequent air filter replacement.
The Function of Air Filters
The main function of a heating and air conditioning system is to pull in air, bring it to a certain temperature, and send it throughout the home to keep the house comfortable. The intake will also attract whatever is floating in the air. Filters catch and trap these particles and contaminants before they can enter the unit and affect its performance. They are also important for the health of the residents of the household, particularly those with chronic respiratory issues such as asthma and allergies.
The Frequency of Air Filter Replacement
So, how often do air filters need to be replaced or cleaned? It can depend on the air quality in an area and the type of AC or furnace filter, but there are general rules of thumb for AC filter replacement or furnace filter replacement.
- Filters should typically be replaced (or cleaned in the case of reusable filters) around every three months.
- They should be replaced more often if they get dirty and clogged sooner.
- If someone in the household has respiratory issues or allergies, then changing the filter more often may be the best course of action to ensure good indoor air quality.
The Benefits of Air Filter Replacement
Beyond the health recommendations, frequent filter replacement has many advantages to the HVAC unit. When a homeowner takes the time to clean or change a clogged air filter, they benefit the whole house. It does more than just promote health. Let’s look at some of the benefits outlined in greater detail below.
- Improved Efficiency: The AC unit or furnace will perform well using less energy because it does not have to struggle to pull air through a clogged air filter. This means less energy is used to reach and maintain optimal temperature.
- Money Savings: Less energy used means lower utility bills while enjoying home comfort.
- Improved Indoor Air Quality: Though this has already been mentioned, it is a significant reason for replacing air filters and is worth mentioning again. Clean air filters can help keep the family healthier and improve the air quality in the home.
