It's difficult to provide a fixed timeframe, as the purification process in a new home is unique to each environment.
The reason is that pollutants like formaldehyde are released continuously from new furniture, paint, and flooring—a process known as "off-gassing." The rate of release is not constant and depends heavily on the types of materials in your home, as well as factors like temperature and humidity.
Therefore, the most effective approach is continuous purification. We strongly recommend keeping your air purifier running consistently to capture these pollutants as they are released into the air.
Pro-Tip for New Homeowners: For greater peace of mind, we suggest placing the purifier in your new home and letting it run for a period of time before you move in. This will help significantly reduce the initial high concentration of pollutants.
