 My grandmother had a window fan at her old house and for some reason as a little kid, that thing scared me.  But I digress.  My question here is doesn't running a window fan bring a lot of unwanted dust into the house.  The fan pulls air from the outside and brings it indoors and there's a lot of dust in the outside air.  How do people who run window fans regularly keep their houses free of so much dust?  I have a hard enough time keeping dust off the top surfaces of things and I don't use window fans.   :wondering:

Yes it does bring in dust as does my attic fan. Still enjoy the fresh air coming in until Houston’s humidity makes it unbearable in late May.

It all depends on the area you live in. I personally love running a window fan due to the fresh air it brings in. If I can use it over running A/C, I much prefer it.

I'm curious, what kind do you have?

any open window will bring in outside elements whether you use a fan or not. I live on a busy county road, and i see how dusty my front porch gets so i dont use a window fan blowing "In" at a front window, but use them for exhaust or dont open them and use the rear windows for intake. You still get dust i guess, but after being cooped up in a sealed heated house all winter i refuse to be a hermit in the summer and have the windows shut too, unless it is raining or really high humidity. The house still gets dusty in the winter. There are some modern box fans that have a filter attachment you can use, but my front porch is my summer living room so i dont even bother.

Rob, I don't have a window fan. I never open my windows.  Being in Houston, I just either use the central heat or central a/c.  And of course run vintage indoor fans!!  :clap:

May I suggest a big ole window shaker for those cooler months?

Meet my Belco Hurricane, a daily runner in my home. 12 speeds and reversible. Quiet enough to hear a pin drop on low and strong enough on high to rip doors open. This thing puts Homart to shame.

Photo not taken by me but I currently own the fan in the photo. Did a minor cleanup and service on it since I have received it.

UNot a dumb question at all. My wife is not an open-window type, but I grew up with “natural air-conditioning.” (Must be a Midwest thing; she’s from CA.) No matter how much I try, I cannot convince her neither dust nor burglars will pour in through our windows. Although, here in W Texas the dust is much worse than it was in Kentucky...

When I was a kid, we typically used the window fan to exhaust out of the house, drawing fresh air in from windows open in other areas of the house. The airflow is gentle enough you’re not drawing in too much dirt/dust and the mosquito screens tend to catch some larger particulates. My mother keeps her house immaculate, and she never batted an eye at running a window fan.

If you use the fan to bring in outside air, you can always place an air conditioner filter behind the fan. Even the higher MERV filters shouldn’t cause an issue for the fan. Just a thought.

I used my window fan for the first time last night:

This fan is very powerful, but I was disapointed that I really didn't feel a breeze. This was in a big open room about 30'x30', window & door open on opposite side. I even tried a twin Vornado blowing in the window on the opposite side of the room, and then a Westy Moibileaire at the door, opposite side. I was expecting doors to be sucked shut...

In order to create a breeze, you need an exchange window open on the far side of your home. If the only window open is the one the fan is in, it's just going to pull a vacuum and put a lot of unnecessary strain on the motor.

Due to my home having junky windows, it's mandatory that I have another window open to run my Belco. I'm afraid of what it would do to the windows if the fan tried to pull a vacuum.

I have a Homart just like yours and a fan like that should certainly create a breeze. My Belco cools off my entire home by itself, no assistance. Your Homart shouldn't struggle to do a 30x30 room.

It really does depend on where you place the fan. You should take into account what direction the air is moving outside your home so as to help the fan do its job. In my house I point a 24 inch Lau Niteaire at a south facing attic window. I leave the windows open downstairs and the fan pulls the air through the downstairs windows, up into the attic and out the attic window.

it don't look like you have the side pannel covering the rest of the open window, to work like it was designed you cant have open space around the fan, get that covered up and you will pull doors shut. these were designed to mount to the window frame with a side panel and only opening the window as high as the fan.

That's just a picture of the fan sitting on my workbench, I had the empty space blocked in the window. I'll have to do more testing.
