what is the decibel of this fan on lo med and high?

Asked by mike March 23, 2021
1
Answer

I own this fan. It is definitely not a bedroom fan like some of them other Lasko fans. It is not quiet at all.

calculate 2000cfm/1820 typical = only +10% more cfm (not 20% in ad) at +60% more cost?

This is a quality fan as noted in the product information. It's quiet and better built than the cheaper fans. I have 3 of them that I purchased to replace the cheaper ones that stopped working in my 2nd floor shop above my garage and this fan is much quieter, moves noticeably more air, and I can leave them in on damp foggy days since they are moisture resistant. This is a 5 star product in my opinion.

Does it have a circuit breaker for safety, in case of overheating, water or other problems?

It is my understanding that Lasko box fans have a fuse in the plug.

dB?

Asked by Fersure August 8, 2020

Answer

My experience with this particular fan is that the DBs are too much for a bedroom fan. Unfortunately, almost all of Lasko fans put out different db's. I have about 6, including this one. Some are louder than others. You might try to plug one in at the store before buying it. I have the quietest fan marked so each year I know which to put in the bedroom. The rest are in other rooms.

One out of Three Failed
One of the three fans we bought four years ago failed. Motor burned out on it. The other two are still going for now. So, I had an old lasko box fan which I purchased about 15 years ago that the switch was jacked up. Tore out the motor and blades from that old one and made it fit in the new one. Rewired it to the good switch. Walla! Good fan now! BTW, the old fans are built better than the new ones. Of, course!

Great product
Have this fan for two years now, still operates great. Not loud like high velocity fans
by VerifiedPurchase
Yes.
I made an air purifier using this fan and its box duct taped to some 20x20x1 air filters and BOY does this fan blow! And that's a compliment. Judy 3000 was inaugurated about two weeks ago and has done very well in absorbing the pollen and dust in my home. The fan has 3 settings and I've only been brave enough to use the first. the first setting is so powerful I can cool the hot side of my pillow with it. Setting two could probably blow my cat off his feet if he crosses in front of it. Setting 3 is forbidden knowledge. If I could improve anything it's that maybe there should be a 0.5 setting.. but honestly, I have never been happier, ever, in my life.

So far so good. Fan is about two inches wider, definitely more powerful and seems not as noisy as the cheaper model. Most of the fan seems heavy duty except the switch seems a little cheap. Hopefully it will last

I have been running this model fan for years. Well worth the money over the standard model Lasko fan. The CFM rating is almost 50% higher. Strong, powerful, weather resistant motor. Highly recommend. One note: If you're using as a window fan, recommend Not attaching the legs. They may tear up your screens. But if using on the floor, you'll probably need to use them because of how powerful it is.

Bought this about two weeks ago from Home Depot, and it worked ok the first time I plugged it in. Before the end of the first week, it was sluggish and no matter what setting the knob was turned to it stayed the same speed. Occasionally there were moments when the power seemed to pick up, but imo that is simply more suggestion that there are problems with the motor. Today it quit working altogether. My own fault for not keeping the receipt longer, so I could exchange at the first sign of trouble, but I wanted to post this review to warn others that if you buy this item you better keep yours.

About two of these to move air through the house when my air conditioning went out on me. I put them in the windows and they pulled are through the house very well. I do like the thin design although they are a little unstable even with the feet attached to them. They are definitely worth the price I paid.
