Your air purifier has a safety feature that turns power off if the filter and cover are not properly in place.
using your Oransi
Always operate your air purifier indoors on a level surface. Locate your air purifier wherever you spend most of your time. Typically, a bedroom or living space. Set the fan speed to a level that is comfortable for you. Low settings are less audible. In most cases you can run your air purifier on a very low fan. For a larger living area, consider a higher fan speed when you’re absent and then turn the setting lower when you return to spend time in the room. Air enters your Oransi at the bottom and exits the top, so you can place the unit anywhere in a room. However, be careful that curtains do not block air intake or exit.
