Using AI Forel, you can easily monitor registered ventilation purifiers with your smartphone. AI Forel is largely composed of four pages for each function. On the website, you can check the air quality status by actual value and color, including integrated air quality, fine dust, ultrafine dust, ultrafine dust, carbon dioxide, volatile organic compounds, and temperature/humidity. On the remote control page, you can use your smartphone with the app installed as a remote control to directly control the functions of the registered ventilation purifier. You can use functions such as turning the power on and off, changing modes, timers, and controlling wind speed. On the filter information page, you can check the lifespan information of the current filter. Depending on the filter's lifespan, you will know whether the filter needs to be replaced. On the air information page, you can check the air quality status checked on the website by segmenting it by time, and you can also check information such as ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide.
