Is this better than the small Honeywell plastic floor fans?

I had this in my daughters room, and occasionally in the house, to move air. At highest speed, it does move air, but not at an industrial level. It has a CFM on 185. I like it.

THIS badboy has a CFM of 1,400! HOWEVER though, the reviews are also call that a load of crap.

for $15, a fan like this is worth exactly this price. It's a good value

This one says it has 2 speeds. I have one that looks identical that I bought in the USA back in 2006 with 3 speeds. I use it on low speed a few feet away from my head while I am sleeping. I actually sleep well with the mild hum that the motor makes. At the highest setting, it makes far too much noise to be trying to sleep a few feet away from but also moves too much air to be comfortable from that distance as well. 15 years and still going strong, but I really only use it on the warmest nights in the summer months.

At it's max setting, ~12db less than plastic 16" ped or 20" box on low [hi/max] setting. But pushes out just as much air. Metal blades are much quieter.

The Honeywell pushes air within a 45 degree angle ( may feel stronger at a narrower range). This fan does it within 90 degree angle ( the air flow is more spread out).

Am I reading this right? 185cfm @75W with the honeywell, or 1400cfm at 25W with this? I'll never buy a honeywell if true.

Obviously you're not from S. Korea, or you would know the risks of having a fan running while you sleep (sarcasm)

I bought this fan. Not that powerful and the the claimed 1400 cfm is not close to this number. It is not loud but you can hear some noise.

1400cfm!
I can use it for my new energy auditing business, the blower door apparatus costs several grand and is commonly used at 1500cfm, this is saving me mucho money because its legitimate.

I'm not a physics major/engineer but according to the website below....1400 CFM is not unreasonable. [This fan is 9 inch, not sure the pitch, but it's high velocity not a regular fan.]

According to the general fan law governing axial fans, you will need to know the fan blade diameter and pitch (blade tilt or attack angle) along with the rpm variable to calculate CFM. In this example, a small household fan on a stand has a three-bladed plastic fan with a 1-foot diameter and an 8-inch effective pitch. This means that each revolution of the running fan blows the one-foot-diameter column of air coming through the fan 8 inches toward you after accounting for efficiency losses. The fan is running at 1,200 rpm.

I've experienced 1500 calibrated cfm, at close distance it will bowl you over from such a small point source.
My furnace blower motor is rated for 600cfm iirc. For the whole house.

I can't fully understand what the number means which is why I referenced that a simple household fan performs ie 1200 CFM.

A good kitchen exhaust fan can pull 1000 CFM but I'm not anywhere scared of being pulled up into it? So how does your 1500 CFM translate into "bowl you over"?

A kitchen exhaust fan that actually pulls 1000cfm (under expected static pressure) will need a large opening to achieve it and from a small footprint is very powerful.
1400cfm from a nine inch fan is going to be like a vortex of air. It is far more likely that this fan puts out 140 cfm.

these are trash. I've had a honeywell for 4 years and lots of hours on it, even used 24/7 to circulate a woodstove at one point and still going strong. This fan lasted one summer before quit. It's noisy and moves less air.

No freakin way it's anywhere near 1400 cfm, 140 maybe. My 19" high velocity fan is only rated 1200 CFM, and it's already loud enough that you wouldn't want to be in the same room when its running.

How is the free replacement?
