EPA Zone
Zone 2
Florida is mostly Zone 2 with moderate radon. However, parts of the Florida panhandle and Alachua County show elevated readings due to phosphate-rich soils.
📋 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 Florida
Mold Exposure
HIGH RISKMold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.
High Indoor Humidity
MODERATEHumidity above 60% creates ideal conditions for mold, dust mites, and bacteria. It also increases off-gassing of VOCs from furniture and building materials. The EPA recommends 30-50% indoor humidity.
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.
Florida Climate & Air Quality Factors
Year-round heat and humidity make Florida the #1 state for mold growth. Hurricane damage causes massive water intrusion events. Air conditioning runs constantly, recirculating pollutants.
