Zone 2
Texas is mostly Zone 2. The Panhandle shows Zone 1 readings. Houston and Dallas-Fort Worth metro areas average moderate levels. Hill Country can show elevated readings.
📋 Testing recommended
Even in Zone 2, the EPA recommends testing every home. Radon varies house by house — your neighbor's low reading doesn't guarantee yours is safe.
Top Indoor Air Hazards in Texas
Mold Exposure
HIGH RISKMold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.
Gas Stove Emissions (NO2 and Benzene)
HIGH RISKGas stoves release nitrogen dioxide and benzene even when turned off. A 2022 study linked gas stoves to 1 in 8 childhood asthma cases. Benzene is a known carcinogen that spreads throughout the home.
Volatile Organic Compounds (VOCs)
HIGH RISKVOCs are emitted by paints, cleaning products, air fresheners, and building materials. Concentrations indoors are up to 10x higher than outdoors. Long-term exposure damages liver, kidneys, and the central nervous system.
Texas Climate & Air Quality Factors
Extreme heat drives year-round AC use. Houston's humidity creates severe mold risk. Oil and gas operations across the state create VOC and methane concerns. Border region colonias often lack proper ventilation.
