👉 Mere fumes refer to the subtle, often invisible vapors or odors that can permeate the air in a given space, typically originating from everyday sources like cleaning products, paint, or even natural materials like wood or plants. These fumes are usually low concentrations of chemicals and can be easily overlooked, but they can still have noticeable effects on health and well-being, causing symptoms such as headaches, dizziness, or respiratory irritation. In environments where ventilation is poor, mere fumes can accumulate to levels that pose significant risks, making it important to monitor and manage indoor air quality to ensure a safe and healthy atmosphere.
