Where does indoor air pollution come from?


While the average person usually drinks only 2 to 3 liters of water each day, we breathe in approximately 10,000 liters of air on a daily basis. Over a lifetime, this translates to hundreds of millions of liters of air pulled into our lungs, providing a direct pathway for toxins to enter our bodies and compromise our health.  Given that we spend about 90% of our time indoors, indoor air quality becomes a key to wellness and a healthy home.  At AirLab we have two goals:  Help homeowners accurately assess the indoor air quality of their home, and increase awareness to minimize daily exposure to indoor air toxins.


Get to know your home.


Chemicals can gain entry into your home by several routes.  Pollution outside of the home can be pulled into the home's heating, ventilating, and air conditioning system and circulated throughout the home.  Nearby highway traffic and manufacturing facilities are examples of sources of harmful toxins which can enter the home from outside.

What's more, allergens, such as mold, dust, and pollen, can invade the home from the outdoors and cause health-related problems for sensitive family members.

Under your home
Harmful chemicals can also be pulled from underneath your home through cracks and other points of entry in your home's foundation.  These chemicals can originate from nearby contaminated groundwater or soil.  Groundwater and soil can become contaminated from a neighboring landfill, leaking underground fuel lines or storage tanks, or improper disposal or accidental spills of industrial solvents.

This migration of chemicals into the home from underlying contamination is referred to as vapor intrusion and has been identified by the EPA as a potentially significant public health risk.

Chemicals in the indoor air can be emitted within the home.  The products we use and store in the home every day, as well as the materials used to build and furnish the home, can release chemicals.  Cleaning products, paints, paint thinners, adhesives, lubricants, gasoline and the lawn mower in the garage are all potential sources of toxins which can pose health risks.  Even air fresheners and scented candles can produce dangerous chemicals in your home.

Where do I go from here?

First Step: Testing
There are literally thousands of possible chemicals and other toxins that can be present in the indoor air of your home.  Protecting your family begins with testing your home for the most common contaminants and toxins which elevate health risk exposure for your family as determined by the EPA.  The AirLab Test Kit was designed to enable anyone to accurately test the air in their home, and taking a sample of your air is as easy as making toast!  See the Kit. >

Second Step: Education
Your AirLab Report will tell you if any of these common toxins are present, the estimated levels, how your air compares to typical homes and the relative health risks to you and your family.  See a sample report. >

The levels of hazards in your home can often be reduced by following a few simple steps.  Learn more. >

The average American spends about 90% of his or her time indoors, and the EPA says toxin levels in the indoor air are about 2 to 5 times higher than outdoor levels.
