How Important Are Air Filters?
People spend most of their time indoors enjoying the controlled climate, making indoor air quality crucial to health. Luckily, there are precautions put in place in heating and air conditioning systems intended to reduce peoples’ exposure to dirty air and pollutants indoors and even more that can be installed. One of these precautions is air filters, which are part of every heating and cooling system. Here is a quick discussion about the importance of air filters and how to use them to keep the home's residents healthy.
What Is the Purpose of Air Filters?
The truth is air filters are not only intended to clean up the air in a home. Luckily, that is a fortunate effect, but one reason air filters are installed in a climate-control system is to protect the equipment. In every HVAC system, the air in a home is recirculated many times per day. Over time, the pollutants in the air can adhere to critical components and impede efficiency, causing higher energy bills and mechanical failures.
Air filters capture contaminants like dust and pet dander, preventing them from causing damage to the AC or heater and hindering efficiency. More effective filters like HEPA air filters can also be used to remove smaller particles from the air. However, they can reduce airflow in some systems because they have greater filtration capabilities. An HVAC technician can help homeowners determine how to best filter the air in their homes.
When Should Air Filters Be Replaced?
Replacing or cleaning air filters should be done on a schedule to maximize the protection of the system and prevent health effects. Most filter manufacturers recommend changing filters at least every three months, but they should be replaced more often if they get dirty sooner.
Some filters may recommend replacement at different intervals depending on the desired cleanliness of the indoor air and the type of filter. If the air is still laden with dust and residents experience symptoms of poor indoor air quality after filters are changed, more frequent filter changes or higher quality filters may be needed.
What Are the Benefits of Timely Air Filter Replacement?
Replacing air filters on time or when needed can provide benefits like:
- A lower likelihood of mechanical problems with the air conditioner or heater
- Improved indoor air quality
- Reduction of allergy and asthma symptoms
- Improved system efficiency, leading to lower heating and cooling bills
- Longer lifespan for the HVAC system
