According to the EPA, indoor air can be more polluted than outside air. Some indoor pollutants are asbestos, carbon monoxide, radon, volatile organic compounds, formaldehyde and pressed wood products, cleaning supplies, pesticides, lead, and second hand smoke. When you paint use rollers and brushes instead of sprays to cut 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 air tight containers. 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. If you live in an area with high radon potential, test your home and above all, don’t smoke.
