Buying a Fan? My Tests Show Why Airflow Speed Isn’t As Important As You Think
Summer heat waves call for powerful cooling fans, especially if you’re trying to use less central air and trim your energy costs during warm months. When perusing fans in-store or online, one spec always stands out: airflow. Manufacturers put a heavy hand on airflow, convincing you that more speed means better cooling comfort. It all sounds good until you dig in — and so I dug in.
My lab data tests showed that airflow speed, while certainly a factor, is just a part of the equation. You’ll want to consider the fan’s motor type, design (standard or bladeless) and how much energy it uses in order to gauge value over time. Buying a cheap, inefficient fan with a high speed rating may seem like a steal — but bad design may end up costing you more on your electric bill.
I found that the more efficient — and sometimes more...
