Sutechnology - No More Smelly Restrooms

Crowded public restrooms and home bathrooms always contain unpleasant odors. CEO Kim Sang-gyu of Sutechnology(http://sutechnology.kr/) wanted to help create more pleasant bathrooms by eradicating bad odors. As a result, he came up with an odor-removing product called "Etish." Let's take a closer look at this quite unusual product.

CEO Kim Sang-gyu says he had a hard time because of bad odors in public restrooms and his home bathroom. He tried various products, from air fresheners to matches and aroma candles, but instead of eliminating the unpleasant odors, they only concealed them. He realized that it wasn't a fundamental solution to eliminating the bad smell. He decided to try a local exhaust ventilation system that he used while working at Hyundai Motor Company. The purpose of a local exhaust ventilation system is to remove odors and harmful substances before they spread to other areas. After coming up with this idea, CEO Kim founded Sutechnology in 2013 and launched the development of Etish in earnest.

Capitalizing on Human Body Gas Property to Melt Easily in Water
Etish, a combination of the words "etiquette" and "fresh," absorbs unpleasant odors into the toilet before they spread all over the bathroom and melts them in the water. After a long observation, CEO Kim managed to find the pipe connecting the toilet to the water tank, and focused on the fact that ammonia and hydrogen sulfide, the main culprits of unpleasant odors, melt easily in water. The Korea Conformity Laboratories has found that the Etish freshener can remove 95 percent ammonia and 90 percent hydrogen sulfide. Sutechnology has earned recognition for its outstanding odor-removing technology, and applied for five Etish-related patents in Korea and seven other countries, including the U.S. CEO Kim says that the performance of this technology is guaranteed by essential patents. The latest, third version of Etish is less noisy and has upgraded features compared to the previous two versions.

How Etish works
Etish can be regulated in four steps. In step one, it emits 70cc per second, and in step two it emits 100cc per second to remove odors. CEO Kim says that Etish, which effectively eliminates bad odors, performs even better when used with a special cover (soft, hard, bidet types), which is equipped with a weight recognition button and only works when a person is sitting on the toilet.

Cost-effective and Hygienic
The use of Etish enables consumers to save costs and maximize hygiene. By eliminating odors, this product eliminates the need for users to flush the toilet in the middle, thus preventing infections that can be caused by splashing water and helping to conserve water. CEO Kim says that it costs 3 cents a day to flush the toilet for one person. Therefore, by using Etish, consumers can save US$24 a year. For a family of four, which uses the bathroom about 20 minutes a day, the annual electricity costs associated with the use of Etish are less than 70 cents. CEO Kim added the trial use of Etish in public health centers, hospitals and schools received a positive response.

“The third version of Etish, which is more complete, has paved the way for its full-fledged marketing. We aim to sell 15,000 units this year and increase the sales volume to 30,000 a month three years from now," says CEO Kim.
