Customer Reviews

Not bad for a $16.60 fan!
I bought this fan at Walmart. In fact, I bought two window fans because I didn't think this fan would be worthy. I got home that night around 11:45pm. It was 81 degrees in the house, but outside it was nice and cool. I set it up and it really pulled the cold air in. The temp dropped to 73 with the fan on. Nice.

My windows are new casement type windows and this one fits perfectly. It has a extension that will make it longer and at the other end, there is a pull out extension that will make it even longer.

I'm returing the other one which is a HAWF2026 - it just doesn't have the extra extension and the adjustable one (doesn't have any of them).

I really wished they put a more powerful motor in these, but for the price it's not bad. If there is a more powerful one I'll buy it. I'll give it a 4 star because it's not powerful enough, but it works great!

BTW, I do have AC in the house, but why use AC when the outside air is chilly already!

MY HOME EXHAUST FAN
I bought this thinking that it can be used as an exhaust fan for my kitchen. I don't like the smell of food inside the house so I gave this a try. It has two fan settings which in my opinion is a good option. Operational sound is quite loud but it works pretty well by circulating the air in the kitchen and removing that awful smelling fumes. Price is reasonable.

Good item for the price
The fan is a very basic model.
Pros
- Easy to install and comes with a side panel to block the window opening
- Cheap
- Can be used for venting as well as getting air in
Cons
- A little noisy for the air that it pushes through (relatively low CFM for the noise level)
- Twin fans cannot be controlled independently
- Venting or getting air in is controlled manually by reversing the fan.
