Causes of Poor Indoor Air Quality

Updated: Feb 10, 2023

Indoor air quality is not something many of us think about until we experience allergy symptoms indoors. Poor air quality can affect your health over time, and you shouldn’t ignore it. But what exactly causes indoor air quality to decrease? Here are four of the most common sources of poor indoor air quality and how you can start breathing easier in your home today.

Indoor View

1. Low Quality or Dirty Air Filters

Poor quality air filters can be a simple cause of lowered air quality. Although cheaper fiberglass mesh air filters may save you money, it might cost you in terms of air quality. These air filters catch dust and larger particles, but often allow many smaller particles through, and can quickly lower the air quality in your home. Opt for high-quality air filters like the HEPA Bypass Filtration System, and ask your HVAC technician which air filter is most compatible with your system.

After you replace your air filter, don’t ignore it. Check it once a month to see if you need to change your AC filter. A dirty filter loses efficiency and can reduce clean airflow to your HVAC system.

2. Too Little or Too Much Humidity

Although it’s a rare problem in a humid climate like Florida, low humidity can pose a problem. When your house is too dry, dust can more easily become airborne and can cause you to breathe in more pollen, mold spores, dust mite debris, dander, lead particles and other pollutants. Since dry air also dries out the nasal passages, you can also be more prone to infections. If your home is too dry, consider installing a humidifier to bring some moisture back in.

On the other hand, houses with too much moisture can also be a huge problem too. High humidity aids mold growth and provides a more suitable environment for bacteria and viruses, and can increase dust mite populations. Breathing in dust mite waste is a common cause of allergies. If you don’t already have one, a whole house dehumidifier can be a great help in this situation.

3. Dirty Ductwork

Dirty ductwork offers an ideal environment for mold growth and other pollutants that lower air quality. As air blows through the ducts, it is pushed into your home along with unwanted particles in the ductwork. If your home is old and you have never had your ducts cleaned, or if your ductwork has gaps or cracks, it is likely that dust, insects, mold spores and perhaps even rodents are residing there.

4. Poorly-Maintained HVAC and Ventilation

When your HVAC system is not kept clean and running as it should, it will lower air quality by allowing particulates or even gasses, such as carbon monoxide, to mix with your indoor air. Likewise, inadequate ventilation can cause a buildup of toxic gases and allergens in the home. Get both inspected and upgraded for safer air quality.
