The air that we breathe can contain some pretty nasty stuff, which is why AC units must be checked frequently to see if the filter is still doing its job. A dirty filter is essentially no filter, allowing hazardous particles to enter the air conditioner and into your home. But just what do these air filters keep out of your lungs?


1. Mold Spores

Without air filters, mold can enter your home and begin to grow. Some of the health risks of high levels of mold can include nasal congestion, throat irritation, skin rash and respiratory problems.

2. Pet Dander

Similar to dandruff, pet dander is made of skin cells is essentially material shed from animals. Pet dander can cause some people to experience allergies, including nasal congestion and sneezing.

3. Soot

If someone in your household is a smoker, there is a good chance that soot will enter your air. Increased exposure to soot can cause heart problems and coughing attacks.

4. Bacteria

These tiny particles can carry a number of viruses, like the common cold or influenza. The chance of catching one of these dangerous viruses can be significantly lowered with a clean air filter.

5. Dust

Composed of various particles in the air, dust is extremely common and can cause strong allergic reactions, especially to asthma sufferers. A fresh air filter and frequent cleaning can help to eliminate dust.
