Can a Dirty Air Filter Make You Sick?

Dust and allergens in your home can cause a range of physical symptoms, such as headaches, fatigue, chest tightness, and a disorder of cold symptoms. A dirty air filter can be ineffective in controlling them. When the filter is clogged, it restricts airflow and causes your heating and cooling system to work harder than it should, leading to premature wear and tear, total system failure, or costly utility bills every month. If the air filter is clogged and can't keep contaminants out of the air as they should, those elements can return to the air you breathe.

This could cause itchy eyes or throat, headaches, and more. In the long-term, it could lead to heart disease, respiratory disease, and even cancer. A clogged filter can also cause unwanted moisture to stick around and cause mold, which is a pain to remove and can lead to long-term health complications. So why not protect and preserve the expensive systems that heat and cool your home, and keep your family comfortable during hot summers and cold winters? Changing your home's air filter is one of the simplest ways to do it.

HVAC air filters work in partnership with your home's heating and cooling system to keep it running smoothly and efficiently. With some of the major filter providers, you can set up an automatic renewal option that will send filters to your home based on a set delivery schedule. Given the money you've already invested in your home, not changing air filters regularly just doesn't make sense. When the air filters are loaded, the air flow capacity is reduced as designed through the duct system.

These arrows indicate in which direction to install the air cleaner to match the direction of the air flow. Air filters that look dirty should be replaced as soon as possible, even if they say they last longer than a month. The good news is that you can improve the air quality in your home quickly, since it only takes a few seconds to change an air filter. The high flow means that more air can flow through the filter more easily, making the oven work efficiently.

If you have an HVAC system or oven, it's important to understand the need for a clean air filter that could otherwise make you or your family sick.
