Never use chemical cleaners or solvents to clean the Lasko heater, as damage to the heater may result.

Lasko heaters are portable electric heaters meant for home use. The heaters are designed to heat small spaces like individual rooms or apartments at one time and require at least 12.5 amps of power for proper use. Other requirements for proper use include regular cleaning of the heater to remove dirt and dust that may obstruct air flow and could even pose a fire hazard. Cleaning the Lasko heater on a regular basis can help maintain proper function of the heater.


Step 1

Disconnect the Lasko heater from the power outlet. Wait for the heater to cool fully before proceeding.

Step 2

Use a vacuum cleaner with a brush attachment to clean the top grille, pulling dirt and dust up and out of the installed filter. Don't disassemble the heater to access the filter.

Step 3

Wipe the sides, front and back of the Lasko heater with a soft, dry cloth.

Step 4

Plug the heater in before turning it back on.
