With concern growing about molds, allergens and indoor air quality, residential duct cleaning is an emerging industry. The National Air Duct Cleaners Association asserts that removing contaminants from a home's ventilation system is an important step toward improving indoor air quality. However, the Environmental Protection Agency (EPA)[1] says knowledge about air duct cleaning is in the early stages, and there is currently no evidence that a small amount of household dust or other particles in air ducts poses any health risks. The EPA indicates it might be warranted in some cases but not in all situations.

Did you know that about 87% of U.S. homes now include an air conditioning unit? We depend on that hidden network of vents and ducts within our homes to keep us comfortable and to keep our air clean. Yet even the world’s biggest clean freaks don’t unscrew their vent covers and clean their home’s heating and cooling ducts.

That’s one of the reasons the air quality inside your home can actually be much, much worse than the outdoor air quality in your region. We don’t say this to scare you, but because we know that air pollution has an outsize effect on pregnant women and unborn babies.

So what do pregnant women really need to know about indoor air quality and pregnancy? Do you really need to clean out your home’s ducts when you’re expecting?

The EPA does recommend air duct cleaning in the event of an animal infestation, mold growth, or issues related to lingering odors like cigarette smoke. When it comes to indoor air quality and pregnancy, these are the biggest risks to be aware of. In addition, homeowners that have ducts that are truly clogged with debris, dust, or other particles should pursue duct cleaning if those elements are being released into the home.

The quality of the air you breathe can contribute to health problems like asthma and allergies. And it’s not just outdoor air quality that exposes us to pollutants. The World Health Organization (WHO) says 9 out of 10 people worldwide regularly breathe polluted air. And as many as 93% of children under 18 are living in environments with pollution concentrations that exceed WHO safe air quality guidelines.¹

You can't always control outdoor air quality, but you can ensure better health for your family by improving indoor air quality. That starts by identifying levels of indoor contaminants and finding ways to restore good air.

If you notice indoor air quality problems, you may scurry to do a few common sense things like duct cleaning and installing carbon monoxide detectors. But some indoor air quality problems, like the presence of mold spores or radon, can be more elusive and require professional help.
