What is Making My Indoor Air Quality Bad?

When it comes to indoor air quality, many homeowners believe that the biggest threats to their residence are external forces: pollen, humidity, smog, and so on. The truth, however, is that there are elements inside many homes that can decrease the quality of the air. Below, let's look at some sources of air contaminants that homeowners are not always quick to recognize.


Pets are a beloved addition to so many households, but they are also one of the key contributors to air quality contaminants. Cats and dogs produce dander that can usually be detected by humans (via an odor), but the hair on their bodies is also a vehicle for dust, pollen, and airborne microbes that can be introduced from outdoors.


Do you have a fireplace? Is there a smoker in the house? If so, it's likely that these burns are introducing contaminants into the air. Respirable particulates and polycyclic aromatic hydrocarbons result from tobacco products, wood burning, and even gas heaters.

Standing Water Humidifiers

This containment source is counter-intuitive because humidifiers are usually used to help improve air quality. Standing water, however, can be a breeding ground for contaminants that can be introduced in the air. Because of this, humidifiers should be emptied shortly after their use.

Dirty Furnace Or Air Conditioning Filters

Your HVAC system circulates the air around your home, so it's absolutely critical to ensure that your furnace and air conditioning unit is outfitted with a new filter every season. Without one, your HVAC system is not only delivering contaminates to your home, it's introducing new dust particles that have accumulated on the filter.
