By any chance, do you know?
The fact that you have to turn off
the air purifier when you need it the most
Khanfilter is the only solution
that can
provide sustainable Performance
even in an environment with rich oil mist/water vapor.
- Turn off the air purifier’s power while cooking.
Oil constituents generated during cooking clog the filter, which shortens the filter’s lifespan. - Use the air purifier after ventilating by opening the window when cooking.
Cooking emissions more harmful than cigarette smoke
Why is lung cancer increasing?
If lung cancer occurs in the lungs themselves, it is called “primary lung cancer,” and cancer caused by cancer spreading from other organs to the lungs is called “metastatic lung cancer.” Based on the form and size of a cancer cell, it is divided into “non-small-cell lung cancer (85%)” and “small-cell lung cancer (15%). Non-small-cell cancer is divided into non-squamous-cell carcinoma (adenocarcinoma and large-cell carcinoma) and squamous-cell carcinoma.
Squamous-cell carcinoma is deeply associated with smoking. The main cause of lung cancer is smoking (about 85%). Smoking increases the risk of lung cancer by 13 times. Secondhand smoking also has an effect, which is 1.5 to 2 times higher than that in non-smokers.
It is noteworthy that lung cancer is increasing in women who do not smoke. Secondhand smoking, smoke generated during food cooking, indoor air contamination and more are estimated to be occurrence factors. The increase in lung cancer detection due to the increased health checkups is also cited as the cause of the increase in lung cancer.
Only an average of 5-15% of lung cancer patients are diagnosed through regular checkups, etc. when they have no symptoms. If symptoms appear, the cancer has often already progressed a lot. Lung cancer symptoms include coughing, bloody phlegm, difficulty breathing, chest pain, weight loss and more. However, since these symptoms can also occur in other lung diseases, it is difficult to identify lung cancer based on symptoms alone. In addition, most of the time, there are no special symptoms in the early stages of lung cancer. In particular, about half of lung cancer that occurs in non-smoking women is not diagnosed at the early stage of complete recovery but at stage 4, where it has already metastasized. The 5-year survival rate of lung cancer is 70 to 90% in the first stage, 50 to 60% in the second stage, 15 to 35% in the third stage, and 5 to 10% in the fourth stage. The earlier the treatment, the higher the survival rate. Regular checkups are essential to detecting lung cancer early.
Large amounts of harmful substances are produced when cooking food
(more deadly than cigarette smoke)
- Cooking emissions such as PM, VOCs, and formaldehyde are first-class carcinogens.
- 94% of female lung cancers occur in non-smokers, which are caused by PM and cooking emissions.
- Cook’s lung cancer is caused mostly by cooking emissions, which were ruled to be an industrial accident for the first time in 2021.
The concentration of PM2.5 during cooking is
13 times higher than the “Very Bad” concentration standard.
Source: Chosun Ilbo, 2019.01.22 / Measurement of changes in PM2.5 concentration by situation of meat grilling
The concentration of PM2.5 measured
during cooking is 1,013 μg/㎥, which is over 13 times the “Very Bad” concentration standard of 76 μg/㎥.
The legislative move is to strengthen
measures to regulate cooking emissions
Special Act on Fine Dust
Date of motion: 2022.05.06
It has made it clear that cooking PM2.5 is included in the survey on the status of PM and has built the basis for the Ministry of Environment to conduct a cooking PM2.5 reduction project.
Occupational Safety and Health Act
Date of motion: 2022.05.06
Added “cafeterias where workers are exposed to fine particles generated when heating oil at high temperatures” to workplaces subject to mandatory work environment measurement
School Health Act
Date of motion: 2022.08.22
Installation of air purification facilities and PM measuring devices in school (kindergarten, elementary school, middle school, high school, and special school) feeding facilities is made mandatory
Due to the influence of judging industrial accidents in the cooking room
Concern for the oil mist issue
at industrial sites is also increasing.

According to a study, 52% of PM2.5 in Gyeonggi Province is made up of ions that are produced by pollutants that are released by automotive emissions, industrial processes, and agro-livestock activities

In terms of environmental, economic, and social values
Innovativeness in technology compared to existing technology
- Collection of more than 90% of PM and odors from various environments
- Semi-permanent use of ceramic filters with self-cleaning functions
- Low installation and maintenance costs
