Indoor Air Pollutants: What They Are and How to Deal With Them

When we think about air pollution, most of us imagine foggy smoke hovering above congested streets. We don’t often reflect on the contamination that occurs within our very own homes. However, it is there, and there are ways to deal with it.

Here, the Beehive Heating and Air experts outline the main indoor air pollutants and the best HVAC technology to address them.

What causes indoor air pollution?

The dust that comes from vehicle exhausts, construction, and other outdoor activities often makes its way indoors. How? Through windoors, doors, and even through a building’s HVAC system.

Inside, air is polluted by mold, dander, and dust. Our beloved pets can also cause problems if their hair is left to hang around in the atmosphere.

For people with allergies or chronic illnesses, this is serious business! It can make a home incredibly uncomfortable and even cause breathing difficulties. 

Another potential air pollutant needs no introduction. COVID-19 spreads contagious diseases by lingering both in the air and on surfaces. This threat has been at the forefront of our minds for over two years now.

Thankfully, there are ways that HVAC technology can support us to purify the air we breathe indoors.

Dealing with Indoor Air Pollutants

Air purification technology like UVC emitting lights can be used to kill contaminants on surfaces. These lights can be installed as part of your HVAC system to ensure it remains free of pathogens, preventing the system from spreading them throughout the building.

Cooling coil disinfecting keeps the evaporator coil clean as well as the drain pan and the surfaces of your HVAC system. The result? Mold is not circulated within it. This technology is often used in hospitals.

Oxidation and ionization air purifiers go even further: they can destroy particles in the air. They remove viruses, bacteria, and mold spores from the air. They’re also used by cleaning companies to remove odors. This works by converting oxygen molecules from the air into changed atoms, deactivating harmful substances within. 

Installing a properly designed ventilation system provides fresh air, controls odors, and removes contaminants. Exhaust fans can be used to reduce the concentration of harmful particles in the air. You may be able to optimize your system by relocating its intakes or removing its ductwork. 

There is also new HVAC technology you can add to your preexisting system, or you could invest in dehumidifiers to maintain a healthy level of humidity in your home.

To increase the filtration efficiency of your system, you may consider switching to HEPA filters which are designed to reduce indoor air pollution. They have the power to trap 99.97% of dust, pollen, and smoke particles. 

The best way to ensure your HVAC system is maintaining air quality in your home is to subject it to regular maintenance. The Beehive Heating and Air team would be happy to perform an inspection and advice on the most effective methods for you to reduce indoor air pollutants.
