Scented products such as air fresheners and candles are usually made from petroleum-based synthetic scents and contain a host of irritants, allergens and carcinogens. Instead, simmer water on the stove adding the real version of your favorite scent, like lemon peel, orange peel, pine needles or cinnamon. If you and your family don’t suffer from allergies, you can simply open the windows. The indoor air in our homes is usually more polluted than the outdoor air -- four to 10 times more polluted according to the EPA -- due to the cleaners and products we use, so detoxify your home by letting the fresh air in.
