  • Never let water, or your damp cleaning cloth, come into contact with the fan motor,
  • Don’t take the unit apart to clean it—despite that this idea makes sense, Lasko manufacturer recommends not to take the unit apart; it can damage the device, void the warranty, and be dangerous to you.

  • Unplug the cord before cleaning—you won’t be diving into the insides and electronics, but use common sense and unplug your fan before you clean it;

Tip: Before cleaning your tower fan, consider your safety.

So, how to clean a Lasko tower fan?

Cleaning the grill

The first thing we want to pay attention to is Lasko fan housing.

A dirty grill cover, full of stubborn dust, is a nightmare, both in Lasko fan and other fans. 

Fan grills are the part of the tower fan that gets the dirtiest in the fastest time. It’s also the most crucial part to keep clean because everyone can see it!


  • a vacuum cleaner, and 
  • a brush extension for your vacuum;

Vacuum the unit’s grill to remove any accumulated dust or dirt.

Use a vacuum with a brush attachment to remove dust and dirt from the fan’s external casing and front and back vents.

Important: Pay attention to areas of your Lasko tower fan where air flows in and out; freeing up those areas of unwanted dirt, dust, and debris will allow air to flow through the fan. You can also use a dust brush or soft-bristle brush in lieu of a vacuum attachment.

If you don’t have a vacuum, you can also use a microfiber cloth, a dust brush, duster, or compressed air to go over the fan blades.

There are several different types of accessories perfect for cleaning the fans:

  • flexible brush—put it on the vacuum cleaner and work along with the grills; the soft tips of the brush will gently scrub the dust. 
  • a duster—the duster’s surface is made from dense chenille microfiber;

Remember that the cleaner the fan, the fresher the air you breathe!

Cleaning tower fan unit

Your lovely Lasko tower fan needs a cleaning every now and then. 

Cleaning the unit is very simple, with a soft, damp cloth dipped in soapy water.

Important: If your fan is laden with dirt and debris, it not only looks terrible, but its ability to circulate air is compromised. 

Here’s what you will need to clean a Lasko fan:

  • Phillips screwdriver or other disassembly tools (optional),
  • vacuum with a brush attachment,
  • dust brush or soft-bristle brush,
  • can of compressed air,
  • all-purpose spray cleaner,
  • rag or cloth;

Some tower fans (Lasko and Vornado are among them) aren’t designed to be taken apart or opened for cleaning.

According to the user manual, doing so may void the warranty, so determine whether you can or can’t do it.

If your tower fan model requires disassembly to clean, use a Phillips head screwdriver or another disassembly tool recommended by the company to remove the back of the fan, as outlined in the manufacturer’s instructions (according to Bgh).

Now you can use compressed air to dislodge debris.

Aim the nozzle tip of a compressed-air can over the vent and slowly release air across the surface area of the fan’s vents. 

Get rid of any stubborn dust or dirt that the vacuum brush failed to remove before.

Plug in the tower fan back into a power source and allow it to run for a few minutes, so any dirt and dust dislodged from the vacuum or compressed air can blow out of the fan. Turn off when you’re done.

Finally, gently wipe down the exterior of your Lasko fan.

Dampen a soft cloth or rag with a few sprays of all-purpose cleaner. Next, gently wipe down the tower fan’s exterior with a lightly damp cloth. Again, we want to eliminate any stray dust and dirt particles. 

It may also be necessary to wipe the surrounding floor to clean up any residue from your newly cleaned fan. 

Lasko tower fans create a high-velocity air stream, i.e., a comforting cooling breeze and circulation that prevent hot air from building up indoors.

Enjoy the clean, cooling air in your house!

Frequently Asked Questions

The majority of dust in our houses is created of dead human skin and hair cells. Our skin cells and pet dander flake off by the thousands every single day, adding up to a lot of microscopic dust particles floating in the air around our space at all times. Other substances compose dust in your home, such as the microscopic pellets discharged by dust mites (who, however, also feed on your discarded skin and hair cells), but it's a small percentage. Most dust particles come directly from our bodies.
Most of the dust particles floating in your house have some sort of electric charge, which causes dust molecules to attract together. Fan blades rush through the air, rubbing and brushing against air molecules and pushing them out of the way. This mechanism results in a charge building up on the leading edge of a blade because of a mechanism known as static electricity. As the dust molecules pass through the air and interact with the leading edge of the fan blade, they become attracted to the charged edge and thus stick there. The leading edge of the fan blade develops and maintains the most charge because of frictional forces and thus pulls in the most dust. Plastic ceiling fans will always be super dusty, thanks to static electricity.
