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 can cause immediate problems such as itchy eyes or throat, headaches, and more. In the long-term, it could lead to serious health issues like heart disease, respiratory disease, and even cancer, according to experts. A clogged filter can also make your heating and cooling system inefficient.
All air passing through your systems must pass through the filter. If the filter is dirty and full of dust, airflow is restricted. This can cause 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. The effects of a dirty air filter on your health are still unclear.
While some studies say yes, others say no, while others say that some symptoms have improved, but others have not. It can cause a total breakdown if your system is working too hard to move through blocked air filters. Air filters that look dirty should be replaced as soon as possible, even if they say they last longer than a month. The effectiveness of each air filter option you encounter can be determined by a rating called MERV (Minimum Efficiency Report Value).
HVAC air filters work in partnership with your home's heating and cooling system to keep it running smoothly and efficiently. If the owner's manual doesn't mention anything about the filter, or if you can't find it, it's generally recommended to change the air filter once a month during busy heating and cooling seasons. The air filter helps trap all dust and other particles, preventing them from entering the air and spreading. The EPA states that some MERV 12 filters and most MERV 13 filters are almost as effective as HEPA filters in reducing airborne particulates related to adverse health effects.
The ACAAI recommends that those affected frequently check their air filters and, if the filter is disposable, replace them every three months. For example, if you don't change your air filters regularly, you may start having more sinus infections. Even if you can't see them, there are millions of tiny particles floating around the air in your home. All the extra work you have to do to circulate clean air through dirty filters will eventually strain your air conditioner parts, which could cause them to break down more quickly. Regardless of why it happens, you might wonder if forgetting to regularly change your air filter is really that important.
Frost buildup on coils or fans makes it difficult for the air conditioning unit to remove heat from the air and cool your home. The answer is yes! Not changing your air filter regularly can have serious consequences for both your health and your wallet. It's important to check your filter every month during busy heating and cooling seasons and replace it when necessary. Doing so will help keep contaminants out of the air you breathe while also keeping your HVAC system running efficiently.
