Japan pushes against PM2.5 house

According to reports from Japanese media, Japanese home builders are vigorously promoting a "fog-fighting house" and the sales momentum is rapid. This kind of dwelling is equipped with a special filter at the vent, which can effectively prevent the atmospheric pollutant PM2.5 from entering the room. Even if the outdoor surface is “dark”, people can also breathe clean air indoors.

Ventilation equipment anti-fog and haze In response to smog, Japan's major residential construction companies have made moves. A company introduced a ventilation device called "ventilation clean 'ef'". Sales of this type of device in 2013 have soared fivefold from the previous year. The installation of such a device when constructing a single-family house can effectively prevent PM2.5 and pollen, dust, and yellow sand from entering the room.

When a company developed a ventilation system, it was originally intended to be used in air conditioners in cold regions. However, as the public's concern about smog and other pollutants has increased, more and more people hope to install such ventilation system in their homes. The air in the house is clean.

"Fog stickers" are favored In addition to homes equipped with ventilation systems, the use of convenient "fog-proof stickers" is also popular in Japan. Among them, the sales volume of a sticker called "Crossing Cottage" produced by Japan's Suminoe Fabrics surged. This commodity grid size is approximately 0.08 mm square and is extremely fine.

The price per square meter of this kind of sticker is about 3,000 yen (approximately RMB 180), and the output has recently been growing. When it is used, it only needs to be affixed to the screen, which can effectively prevent PM2.5 pollen and other pollutants from entering the room.

In addition, Japan YKK AP Corporation has developed a product made of special materials. It is named "The Third Generation of Sunlight Sense" and resembles a sun room, which can block outdoor air without impeding drying of clothes. It is popular in Kansai and Kyushu.
