The World Health Organization categorized find dust as class one carcinogens. Most dust get filtered by nostrils and musous membrane of bronchial tubes but the word ‘fine’ makes it unfiltered and pass down to our body to cause various diseases. Some fine dust is made domestically from carbon emissions and some comes from our neighboring country China as research results found. It means that measures should be brought up both from the government and industry in general. 

We know fine dust from carbon emissions from cars and factories. But not many people know that a house we live in can also generate fine dust. A good example is sash window. Sash is attached with wind breaking hairs for insulation and for preventing dust from getting inside. The problem is that these hairs also become fine dust after certain period of time. 

Yeojin Moon, CEO of Eunjin Tech, saw one day pieces of these hairs floating in the air and stuck onto the window. She made them into calculation and found that their length was 7.5mm and the volume 750mL in total.

“A 115 square meter house normally has 165 meter hairs. It means that they get turned into fine dust equal to 180 credit cards. What makes me worried is that this amount of fine dust is being made from 17 million houses in South Korea every day. What makes it worse is that sash makers seem to increase the amount of the hair for better insulation oblivious of this fact.”

The brainchild of Moon for this was patented ‘Sevenstop’. It has excellent insulation and soundproof. Installation is simple and the price is affordable. All you need to do is to insert Sevenstop to the wheel and the upper part of the windows. If it is a new building, it is highly advisable to use Sevenstop pre-installed windows to reduce cost and to save trouble. Installing system windows for a 115 square meter house normally costs more than $17,000 but installing Sevenstop in sliding windows is 30 to 40% cheaper when compared to system windows.
