Similar to many window models, this unit also comes with auto-locking expanders. The white expanders can expand between 22-1/4″ to 33″ for a snug fit.

Is an exhaust fan the same as a ventilation fan?

We often use a ventilation fan instead of exhaust and that is completely fine. They are just two different words with one work, i.e, ventilation. While you can use the term natural ventilation for spaces with large windows that can gather you fresh air without any electric force, then there’s power exhaust ventilation that uses a small electric fan to maintain proper ventilation. So say it is either exhaust or ventilation, a well-vented area is far better than closed 4 walls.

How do you install an exhaust fan in a window?

By the size of an exhaust fan, you can say it is easy to install all by yourself. And that is completely true, it is a great DIY project if you have the right tools and accessories by side. While many brands already include matching accessories, you might want to keep a basic household toolbox nearby in case(1).

There are two types of exhaust fans, wall-mounted, and window exhaust. Window ventilation is much easier to install than a wall-mounted ventilator fan if you do not have a hole already. Before buying a through-the-wall unit make sure to check your building policies, whether they allow the use or not.

Installing a Wall-Mounted Exhaust Fan:

You’ll Need:

  • Glass Glue
  • Screws


  • Select a good-quality ventilation fan that matches the existing hole in the wall.
  • Now grab some glass glue and begin fixing the unit with dampers out and fan side in.
  • Loosen the panel’s screws to disassemble it.
  • Now try to insert the base of the exhaust fan into the hole, and make the screw position mark.
  • Bore a hole in the market area and drill down screws, followed by plastic stoppers
  • Insert the base of the exhaust fan into the hole and lock the screws

Installing Kitchen Window Exhaust Fan:

You’ll Need:

  • Expandable side panels


  • There’s not much drilling needed with window ventilation. Simply place the unit on the window and stretch out the side panels. Most window vent includes side panels for convenient installation.
  • Once you find a sweet spot, lock the panels in place, plug in the unit, and your vent is ready for use.
  • You can also take off the side panels and use the window exhaust on a tabletop or other flat surfaces.

Where should a kitchen exhaust fan be installed?

Exhaust fans usually go on the sidewall of the kitchen with open space on the other side. This is because the dampers of ventilation fans sit in an open space for proper air circulation(2). Also, the position of the fan should be higher. Keep at least 12 inches of the gap from the ceiling.

You’ll not need to change the filters of a ventilation fan like a range hood as there aren’t any. However, over time, the grease and dirt will accumulate over the fan which is extremely easy to clean by taking its part off. The game is to select a proper location and you’ll see how effectively a tiny fan can remove smoke and cooking odors.

How much does it cost to install a kitchen exhaust fan?

Kitchen exhaust fans are inexpensive and cost you hardly $50 for proper installation. Provided the hole is already in the wall and you need to install a through-the-wall unit, you just need some screws. You can finish installing a wall kitchen fan in less than 30 minutes and under 50 dollars.

Then again, it depends on the type of model you choose. A unit with a thermostat, LED lights, and an energy-star rating will be more expensive. They cost nearly $100 dollars but are worth buying if you need more features. Then there are models with dual fans that effectively draw out hot and smokey air from the room. Twin exhaust fans cost between $30-$150 depending upon the functions you settle for.

So in short, the main cost of installing a kitchen exhaust fan is the unit itself(3). Then all it takes is a power drill and screws for the damper fixture that can be done in minutes.

How do you clean an oily kitchen exhaust fan?

Kitchen exhaust fans not only remove moisture from the space but also eliminate odors, fumes, and smoke. So it is natural for the unit to develop a layer of grease over time. And it is also important to clean the greasy exhaust fan before the grease layers up. A clean fan will not only look beautiful in your kitchen but also reduce the fire hazard. Thanks to the simple design of these units make them easy to clean.

You’ll Need:

  • Microfiber cloth
  • Sponge/soft scrubber
  • Dishwashing detergent
  • Baking Soda(optional)
  • Toothbrush


  • Remove the front panel of the unit, followed by fan blades, and soak them in the liquid solution for a few minutes.
  • Now grab the sponge/soft scrubber and gently wash the front panel and fan blades.
  • Do not soak any parts with electric wiring or motor. You can clean them with a dry microfiber cloth.
  • Sometimes it is difficult to get the grease off from the blades. In this case, you can directly pour a few drops of dishwashing liquid on blades and clean them. If this is not doing the trick, then try sprinkling a generous amount of baking soda.
  • Dip the toothbrush in hot water and scrub the blades.
  • Dampers are not removable so you will have to take a little effort to clean them. Just dip your soft scrubber in the dishwashing solution and scrub the parts you can reach easily. Follow the same on the backside. Then clean them off with water at least 2 times to ensure all the liquid is off.
  • Similarly, rinse the plastic front panels and fan blades with running water. You can either let them air dry or use a microfiber cloth or paper towels for immediate drying. Let the parts dry completely before you attach the fan again.
