About VOCs (Volatile Organic Compounds) — DwellSmart

VOCs, or Volatile Organic Compounds, are chemicals from liquids and solids that vaporize at room temperature and enter the atmosphere (a phenomenon known as “outgassing” or “offgassing”). The United States Environmental Protection Agency (EPA) has found concentrations of VOCs in indoor air to be 2 to 5 times greater than in outdoor air, and they can shoot up to a 1,000 times higher at ...
