However, if the evaporator is not properly maintained, it can become a breeding ground for bacteria and mold, which can be harmful to budgies if ingested. Additionally, if the evaporator is used in a small, enclosed space, it can reduce the oxygen levels in the air, which can also be harmful to budgies.
As long as the evaporator is properly maintained and used in a well-ventilated area, it should not pose any danger to budgies.
