What Happens When Air Filters Get Dirty?

The dirty air filter restricts the air supply to the engine, resulting in unburned fuel that forms a soot residue that accumulates in the spark plug. This fouls the spark plug(s) and decreases its ability to produce the spark needed for the combustion process. A clogged filter reduces the amount of air supplied to the engine, leading to an increase in unburned fuel that turns into soot residue. Soot can build up on spark plug tips, making them unable to generate a proper spark.

This can cause a car to move abruptly, idle, and in some cases, the engine may fail. Air duct leaks introduce dust and dirt from areas such as the attic, which increases the amount of dirt that accumulates in the air filter. When your car is parked, does it sound smooth and even? If your idle is noisy or you hear a vibration or hiccup, you may have a faulty air filter. Your HVAC system's air filter traps contaminants and keeps them away from other essential parts.

Cleaning your air filter can help you avoid costly breakdowns, extend the system's life, and make you and your family more comfortable. You should replace the air filter in your unit at least once every three months for your Jupiter, Florida home's heating and air conditioning system to work properly. A dirty air filter can cause problems such as dirty ducts, poor indoor air quality, and unpleasant odors in your home. Keeping your filter clean and maintained will help you avoid these issues and extend the life of your vehicle.

A professional technician can repair or replace your duct system to ensure that your ducts do not leak, keeping your utility bills lower and preventing you from replacing the filter frequently. The harder the system has to work to extract air throughout your home, the more energy you need and the higher your energy bills will be. A clogged filter continuously recirculates those particles back home, causing you and your family a range of health-related symptoms, including headaches, fatigue, cold-like symptoms that never seem to go away, and chronic allergies. If your home is well-sealed, pet-free, dust-prone furniture such as carpets and cloth-covered furniture, and you dust and vacuum every day, your air filters will have fewer particles that accumulate in the air.

Particulate capture efficiency increases as the filter becomes dirty; accumulation in the fibers reduces openings for air to pass through and allows the filter to capture more particles. If the air filter becomes too congested during the summer cooling season, it can cause a lack of air flow to the evaporator or cooling coils. If you install a new filter but don't turn on the heating or air conditioning until a month or two later, the filter should still be relatively clean since the system hasn't been forcing air through. And when the air in your home circulates through the filter and air conditioning system non-stop, it will pick up dirt and air pollutants at a much faster rate. It's easy to forget about important technical aspects such as engine filters during normal day-to-day driving.

This setting consumes less energy, avoids indoor humidity and means you'll need to change the filter less frequently.
