I have just recently bought this fan, based on my experience with my old fan that had propeller blades identical to depicted on all published images associated with this fan model. This shape of the propeller (with blades similar to elephant ears) is contributing to higher airflow, at the same RPM, vs. shape of propeller with blade looking like rabbit ears, and which is lately used on majority of inexpensive box fans sold under brand names Lasko or others.

To my surprise, the fan that arrived per my order, while having on the box a correct model number and image as on this web page, has propeller identical to less expensive Lasko brand box fans.

In fact, Air King is subsidiary of Lasko, as I discovered while contacting the Air King.
In short, this fan went through a typical to current times "cost reduction reengineering" by someone who has no clue about air dynamics of propellers. As a result, the fan is noisier than before because it has to rotate faster, due to the new shape of its propeller blades, to produce a similar airflow, and is no different from all other box fans on the market, but is a twice as much expensive.
Do not waste your money. Note that I was told by customer service of the company that, from now on, this fan model will have the same propeller as supplied with Lasko brand fans. The company "didn't have a time" to replace this fan's marketing images. In addition, I found that warranty period on the fan has been reduced from 3 years to just 1 year.
