Odor or smells are caused by various trace amounts chemicals in the air, such as ammonia in public toilets or hydrogen sulfide in livestock farms. Due to its complicated compositions, traditional methods are very restricted to solve this problem which has been with us for thousands of years, some might be effective but need big industrial facilities, some might also be harmful and dangerous. The nano photocatalytic technology-based odor elimination system is a brand-new deodorizing solution, so we can use it everywhere easily, lightly safely. We don't need to use perfume cover the odor, absorb odor into some materials and worry about its abandoning process, or worry about ozone's dangerous to health anymore. Now our nano-coating can effectively decompose the stink directly at the molecular level and convert them to harmless inorganic substances such as water and carbon dioxide. Photocatalyst itself is a safe chemical substance with no extra pollution; it works as a catalyst in the reaction so that its performance maintains a longtime. Photocatalytic oxidization reaction is effective in most odors' decomposition, so it can be widely used from daily life to the industrial process for eliminating all the odors and smells. We are able to provide the products being compatible with diversified surfaces to fulfill the odor elimination demands from various industries. Since we don't need a big facility and electronic support to make it work, our odor control solution can be used for flexible fields, such as control smoke smell, pet smell, and even sweat smell and incredible surface, i.e., textiles.
