Can an air purifier be used after whole-house customization is installed?

An air purifier can be used, but it is only an auxiliary measure and cannot replace opening windows for ventilation. A purifier has some filtering effect on free formaldehyde that has already been released into the air, but the part continuously released from inside the panels still has to be carried away by ventilation and air exchange. It is recommended to open windows for cross-ventilation during the day, and to turn on the purifier at night or on hazy days when the windows are closed; remember to replace the filter on schedule. In addition, open the door panels and drawers so that the air inside the cabinets also circulates, and only then will the effect be noticeable. To really judge whether it is habitable, the test results should still be the basis.
