How many CFMs does this fan give off?

I bought this 2 yr ago after having a more powerful one for 10 yrs. Wish this had more cfm's. It's a good sturdy all metal fan but disappointed the air it puts out. Needing another fan and just ordered a 4650 cfm for less $. Hoping it will move more air. It seems like every year things are made cheaper and cheaper.

I know this is an old question but most of these replies stating it’s “so loud” is just ridiculous. It’s all subjective. The “noise” is to be expected. The description says, “high velocity”... you can’t have a lot of air movement without noise. If you don’t like noise, buy a weaker fan. With that said, I have a different brand floor fan that looks very similar to this, and at its highest speed, it is much louder than this fan... but it also pushes more air than the Lasko. Let’s get real people. Do you want a powerful fan or do you want a quiet fan? If you can’t deal with noise, get a smaller fan and run it on low speed. This 20” Lasko fan is considerably “quiet” for its size. But as I said above, it is not as powerful as a another fan of the same size... which is why it is considerably more quiet. With that said... the amount of “noise” to be perceived is subjective. One person may have had weaker smaller fans their whole life... which in this case, this fan may seem “noisy” to them. I personally have been around many different fans, loud ones, small weak ones, huge powerful ones... plus my understanding of noise in relation to airflow may be better than someone who just thinks about sound as a negative. So, to better elaborate one someone’s explanation to this question. Low speed is tolerable in a standard size living area while watching TV... on a day which is about mid to high 70’s. Medium speed is tolerable in the same environment on a day which is in the low to mid 80’s. The sound on high speed is tolerable in the same exact environment on a day which is above 85 degrees.

Do you have to oil the motor now and then?

This fan uses a brushless motor design and bushings for the motor. I have one that I turn on every night before bed and let run for 8 hours or so daily. I think we are looking at possibly 5k hours if operation so far. As far as maintenance on the unit every so often you have to blow the dust off the unit to keep the unit from over heating, and I have once lubricated the bushings with grease due to vibrations/ noise while running. Because the motor is brushless the only wear item is the motor bushings etc. From what I understand brushless motors have a lifespan of around 10k hours...

can you clean the blades?

It is NOT what I'd call "easy" to clean. Yes, the front cover comes off without any tools, but you're gonna have to get some wet rags behind the blades, because they're not coming off too easy. And the rear grill also doesn't come off. Compared to my Honeywell fan, where I can completely remove front AND rear grill along with the blades (zero tools) and spray them off in the shower and have them looking 100% brand new in all of 2 minutes, this fan sucks to clean. Yes, you get a more power in the Lasko, but cleaning stinks....
