Indoor Air Quality (IAQ) testing is essential for homeowners, landlords, and businesses to ensure a safe and healthy environment. Poor IAQ can result from pollutants such as mold, allergens, volatile organic compounds (VOCs), carbon monoxide, and other harmful contaminants. These pollutants can lead to both immediate and long-term health issues, including respiratory problems, allergies, fatigue, and more severe conditions like asthma or cardiovascular disease.
