2. Find the right filter.
Not all water filters are created equally. To filter out chlorine, be sure to look for NSF/ANSI Standard 46, which means it’s third-party tested to effectively remove chlorine. If your water test turns up elevated levels of other contaminants, make sure you buy a filter that is certified to remove them.
3. Clean up your cleaners.
Be picky about the products you use to clean not only your house, but your body, too. Choose plant-based soaps, like certified-organic Dr. Bronner’s Magic Soaps, and avoid shampoos and soaps that are artificially scented by steering clear of ingredients like “fragrance,” “parfum,” and “linalool,” a compound found in certain plants, but usually in a synthetic form in personal-care products. And wash your hands clean of ever using the antibacterial chemical triclosan, which messes up hormone function and is linked to the spike in antibiotic-resistant superbugs.
