Indoor Air Quality Is a Serious Health Issue
Radon: The Silent Lung Cancer Cause
Radon is responsible for approximately 21,000 lung cancer deaths annually in the US — more than drunk driving. It's invisible, odorless, and present in every home to some degree. The only way to know your level is to test.
Mold: Hidden, But Detectable
Mold spores trigger asthma and allergies, and can grow behind walls, under flooring, and in HVAC systems — invisible to the eye. Air quality mold testing can detect active growth before it becomes a major remediation project.
VOCs & PM2.5: Everyday Exposures
Indoor air can be 2–5× more polluted than outdoor air, according to EPA research. Cooking, cleaning products, new furniture, and attached garages all contribute VOCs and fine particles that affect respiratory health and cognitive function.
A Practical 4-Step Approach
Test for Radon First
Radon is invisible and odorless. A $15 charcoal test kit or a $90–$200 continuous monitor will tell you your home's radon level. Test in your basement or lowest livable floor.

An indoor air quality monitor tracks CO2, VOCs, PM2.5, humidity, and temperature continuously. These readings reveal invisible problems affecting your daily health.

Maintain 30–50% indoor humidity with a quality dehumidifier. If you suspect mold, use an air sampling kit before hiring a costly professional.
