How to Clean It


Even though it doesn’t require thorough maintenance, you still have to take care of it just like any other appliance. Luckily, this won’t take long as there are only a few steps to follow through with so that you ensure the fan’s lifespan is extended to the max and that its operation is maintained up to par.

  • Step 1 –Unplug it and take it out of the window frame. As a rule of thumb, you have to remember that if you want to place it on the floor, you will need to place a plastic sheet underneath it in order to clean it up easily after
  • Step 2 –With a screwdriver, take out the screws that are on the edge in order to remove the grill. Please be careful where you place the screws as they are very small and chances of losing them by accident are high. Then, remove the piece of equipment
  • Step 3 – Remove any of the matter found in it with your hands or a small hand vacuum cleaner. In case you want to do a thorough cleaning, you can use a mixture of a cleaner and soap of your choice. Then, use a sponge or a cloth to remove the excess liquid
  • Step 4 – Don’t forget to clean the exterior as well. This includes the blades, grates, grill cover, and knobs. Do not use the same cloth or sponge that you’ve used for the inside. Finally, put it back together and redo the process after 6-8 months
