Yirumi Co has commenced manufacturing ventilation air purifiers to convert contaminated indoor air into clean air.

The company explained it isn’t always possible to ventilate freely when the fine dust level is high, so Yirumi developed an air purifier that can bring clean air into the house without opening the window and release bad air from the house.

Bijou Mini is an air purifier that can ventilate without opening the window. It is installed, around the window, as a 6.4cm guide bar.

In addition, if customers use a double window, they don't have to open and close the outer window. This is because ventilation is possible without opening the outer window by applying the world's first double guide bar. Maximum power consumption is also very low. It is 13.2W, so customers can use it without worrying about electricity bills.

To use the air purifier, there is a remote-control function that can be easily operated from a distance without approaching the window where the product is installed and pressing the button.

The dust collection filter replacement cycle is 4 months if the product is used 10 hours a day. If there is no filter to replace immediately, customers can touch the power button for more than 5 seconds to initialize the replacement cycle. The pre-filter can be separated and washed, so it can be managed more cleanly.

Finally, Bijou Mini has a four-stage ventilation mode, low-noise mode, and strong mode, allowing ventilation with the amount of air needed depending on the situation, the company said.

Technavio released a research report this week showing the air purifier market is growing at a CAGR of 7.14 per cent between 2021 and 2026.

The size of the market is forecast to increase by US$5.08 billion during the forecast period.
