Are you in a clean air?
~ Let's have enough ventilation in winter~
Compared to old wooden houses, today's houses have an airtight structure with less airborne changes. These houses and condominiums have a small amount of air that can be naturally absorbed. Especially when using heaters such as stoves, windows tend to be closed, and the air gets dirty. Chemical substances volatile from building materials and furniture may cause sick house syndrome, and the concentration of toxic gases generated from combustion equipment such as stoves increases, resulting in carbon monoxide poisoning.
Let's stop closing and open the window from time to time. If possible, open two or more places, the wind is good and effective. Take care of your health by ventilation in winter.
| 1 floating dust | Tobacco smoke and house dust, as small particles, flow in the air. Cigarette smoke contains carcinogens. |

| 2 Carbon monoxide | It is produced when oil or gas is burned in a state where oxygen is insufficient. It is extremely highly toxic and has resulted in fatal accidents. |
| 3 Carbon dioxide | It is produced by human breathing and the burning of oil and gas. Although it is low toxic, it can be used as a guide to dirt in the air. |
| 4 Nitrogen oxides | It is produced when oil or gas burns. It can be a factor such as chronic bronchitis and worsen asthma. |
