It is recommended to clean your Lasko space heater at least once a year, or more frequently if you notice a buildup of dust or debris. Regular cleaning will help maintain the heater’s efficiency, extend its lifespan, and ensure safe operation.

Step-by-Step Cleaning Process

  1. Unplug the Space Heater: Before beginning the cleaning process, ensure that the Lasko space heater is unplugged from the power outlet to prevent any risk of electric shock.

  2. Vacuum the Intake and Exhaust Grills: Using the brush attachment on your vacuum cleaner, gently clean the intake and exhaust grills of the space heater. This will remove any accumulated dust, pet hair, or other debris that may have built up on the surface. Be careful not to apply too much pressure, as this could potentially damage the grills.

  3. Clean the Filter (if applicable): If your Lasko space heater has a removable filter, carefully remove it and clean it according to the manufacturer’s instructions. Some filters can be washed with a mild detergent and water, while others may need to be replaced. Consult your Lasko space heater’s user manual for specific filter cleaning or replacement instructions.

  4. Wipe Down the Exterior: Use a damp cloth to gently wipe down the exterior of the Lasko space heater. Avoid getting any water or cleaning solution inside the unit, as this could potentially damage the internal components. If necessary, you can use a mild detergent or cleaning solution, but be sure to thoroughly dry the surface afterwards.

  5. Dry Completely: Allow the Lasko space heater to dry completely before plugging it back in and using it. This is crucial to prevent any risk of electric shock or damage to the internal components.

Additional Cleaning Tips

  • Use a soft-bristled brush or a can of compressed air to clean the internal components of the space heater, such as the heating element and fan blades, if accessible. This can help remove any stubborn debris or dust buildup.

  • Check the power cord for any signs of wear or damage, such as cracks or fraying. If the cord appears to be in poor condition, it’s best to replace it before using the space heater again.

  • Ensure that the space heater is placed on a level, stable surface and that the air intake and exhaust grills are not obstructed, as this can affect the heater’s performance and efficiency.


By following this comprehensive guide, you can effectively clean your Lasko space heater and maintain its optimal performance. Regular cleaning and maintenance will not only extend the lifespan of your space heater but also ensure safe and efficient operation. Remember to always prioritize safety and consult your Lasko space heater’s user manual for any specific cleaning instructions or recommendations.
