The EPA estimates that indoor air can be more polluted than outside air. Some of the indoor pollutants of concern are asbestos, carbon monoxide, radon, volatile organic compounds, formaldehyde and pressed wood products, cleaning supplies, pesticides, lead, and second hand smoke. Apply paint with rollers and brushes instead of sprays; it cuts down on fumes. Oil-based paints and varnishes contain a high percentage of VOCs, so use water-based paints and solvents and store them in an air tight container. Air out new rugs or furniture before you put them in your home and keep some windows open after you bring them in. Use less toxic cleansers such as baking soda and vinegar and avoid pesticides and instead practice integrated pest management. If you live in an area with high radon potential, test your home and don’t smoke.
