How to Clean It


Even if it doesn’t necessitate thorough maintenance, you still have to take care of it to keep it working properly. Luckily, this won’t take long as there are only a few steps to follow through so that you ensure the fan’s lifespan is extended to the maximum and that its operation is maintained up to par.

  • Step 1 – Unplug it and take it out of the frame. If you are going to place it on the floor for the cleaning, remember to place a plastic foil under it so the dust doesn’t scatter around the house
  • Step 2 –With a screwdriver, take out the screws that are on the edge to detach the grill. Please be careful where you place the screws as they are very small and the 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. To do a thorough cleaning, you can use a mixture of water and soap of your choice. Then, use a sponge or a cloth to absorb the excess liquid
  • Step 4Clean the exterior as well. This counts 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
