How to Test Indoor Air Quality: A Homeowner’s Guide

Are you worried about the air you're breathing at home? You're not alone. Many homeowners are concerned about the influx of dust, allergens, and pollutants in their living space, and for good reason. The air inside your home can be two to five times more polluted than the air outside.

But how can you know for sure what's in your air? Let's explore some simple ways to test your indoor air quality.

How to Test Your Indoor Air Quality at Home

While professional testing provides the most accurate results, there are several DIY methods you can use to get a general idea of your home's air quality:

1. The Mold Test

Mold can be a significant air quality issue. Here's a simple test:

• Cut a piece of clear tape about 3 inches long.
• Press the tape against a wall or surface where you suspect mold.
• Remove the tape and place it in a sealed plastic bag.
• If you see dark spots on the tape after 48 hours, you might have mold.

2. The Radon Test

Radon is a colorless, odorless gas that can cause lung cancer. You can buy a radon test kit at most hardware stores:

• Follow the kit instructions to set up the test in your basement or lowest living area.
• Leave the test undisturbed for the recommended time (usually 2-7 days).
• Send the test to the lab for analysis.

3. The Carbon Monoxide Test

Every home should have carbon monoxide detectors. If you don't have one:

• Install battery-operated or plug-in carbon monoxide detectors on every floor.
• Place them near sleeping areas and at least 15 feet away from fuel-burning appliances.
• Test the detectors monthly and replace batteries as needed.

4. The Humidity Test

High humidity can promote mold growth. On the other hand, low humidity can irritate your skin, nose, and throat over time. Use a hygrometer (available at most hardware stores) to measure your home's humidity. Ideal indoor humidity levels are between 30-50%.

Professional Indoor Air Quality Testing

For a more comprehensive assessment, consider professional air quality testing. Professionals use specialized equipment to test for a wide range of pollutants, including:

• Particulate matter (dust, pollen, pet dander)
• Volatile Organic Compounds (VOCs)
• Formaldehyde
• Asbestos
• Lead particles

Professional testing can provide a detailed report of your indoor air quality and specific recommendations for improvement.

Interpreting Your Test Results

After testing your indoor air, it's crucial to understand what the results mean:

Mold

Any sign of mold growth requires action. Clean small areas with a bleach solution and consider professional mold remediation for larger problems.

Radon

Levels at or above 4 picocuries per liter (pCi/L) require mitigation.

Carbon Monoxide

Any detection of CO requires immediate action. Evacuate your home right away and call emergency services.

Humidity

If humidity levels are consistently below 30%, consider installing a humidifier.

Steps to Improve Indoor Air Quality

Once you've identified any issues, there are several steps you can take to improve your indoor air quality:

• Increase ventilation by opening windows or using exhaust fans.
• Change your HVAC filters regularly (every 1-3 months).
• Use a high-quality air purifier with a HEPA filter.
• Keep your home clean by vacuuming and dusting regularly.
• Control humidity with dehumidifiers or humidifiers as needed.
• Schedule air duct cleaning service
• Avoid smoking indoors and limit the use of chemical cleaners.
