Because although some decorative material has been tested up to standard, but the use of excessive and still produce total volatile organic compounds. 2, after the renovation, the use of chemical ripening method, that allows houses stay idle for some time longer, so that the total volatile organic compounds have the opportunity to distribute. 3, in their daily lives, control and use of the indoor temperature and humidity in addition to formaldehyde to join the training, or the use of ventilation methods, as well as to maintain good eating habits of life, not smoking, drinking less alcohol, etc., reduce the indoor total volatile organic compounds concentration. 4, master of the indoor environment they live in total volatile organic compounds (TVOC) is excessive, often make the indoor environment testing department (TVOC) detection.
