This prevents buildup of particles and odors that could compromise the unit’s performance (Fakhri et al., 2020).
-
Clean the unit: Dust and stains can accumulate on the exterior and components of the air purifier. Use a damp cloth to wipe the outside and vacuum the intake and outlet grills regularly. Clean internal parts in accordance with the manufacturer’s instructions to maintain optimal airflow and efficiency.
-
Monitor air quality: Invest in a smart air quality monitor. This device can provide real-time data on pollutants and humidity in your home. High humidity can exacerbate odors, and controlling it can improve the effectiveness of your air purifier (National Institute of Environmental Health Sciences, 2021).
-
Ensure proper placement: Position the air purifier in a central location of the room, away from walls, furniture, and corners to allow for maximum airflow. Avoid placing it directly near sources of odors such as trash cans or pet areas. This enhances the purifier’s ability to circulate air efficiently and remove contaminants.
By following these maintenance tasks, you can enhance odor control and extend the lifecycle of your air purifier.
