Question: Does this fan have the setting to BLOW AIR INTO and ALSO the setting to PULL THE HOT AIR OUT OF HOME?
Document: I BOUGHT THIS FAN FROM AMAZON. AND IT ARRIVED IN GOOD PACKING I PLUGGED IT IN AFTER I OPENED THE BOX. AND THIS FAN REALLY BLOWS OUT GOOD AIR. ALOT CHEAPPER THEN A A/C UNIT. AND COOLS YOUR ROOM DOWN BY 7 DEGREES IN A MATER OF MINS. WELL IT DID FOR ME. THE PRICE IS KIND HIGH BUT WELL WORTH IT I THINK..
Let's get started...The 20" box fans we'll compare are:A - Aerospeed BX100B - Holmes HBF2002AC - Kenmore 32002D - Lasko 3720E - Lasko 3721F - Lasko 3723G - Lasko 3733H - Lasko B20201DESIGN AND DETAILS:---------------------All have white fans and grills, gray enclosures, 245-260 square inch areas the blades pass through, and 70"-73" cords.A - Aerospeed BX100- Wavy grill (BX200/BX400 have other grills).- Fan speed dial is on TOP.- Little smaller enclosure (you wouldn't notice unless side-by-side), though the blades pass through an area near to the highest square inches of the bunch.- The in-plug mini-fuse is easily replaceable if it blows.B - Holmes HBF2002A (Target)- Simple grid grill, blades have circle connecting them.- Fan speed dial and plug connection are on the MIDDLE OF THE BACK.
This is not ideal if bringing air into the house from a window and not an attractive option when exhausting out.- The in-plug mini-fuse is easily replaceable if it blows.- Looks exactly like the Kenmore 32002.- NEGATIVE: At top speed it vibrates like crazy, enough to move itself.C - Kenmore 32002 (Sears/Kmart)- Simple grid grill, blades have circle connecting them.- Fan speed dial and plug connection are on the MIDDLE OF THE BACK. This is not ideal if bringing air into the house from a window and not an attractive option when exhausting out.- The in-plug mini-fuse is easily replaceable if it blows.- Looks exactly like Holmes HBF2002A.D - Lasko 3720- Circular grill, blue logo on the front, blue speed dial.- Fan speed dial is on TOP.- Lasko promotes this as their fan of choice to PUT IN A WINDOW because it is more RAIN RESISTANT (not weatherproof).- All Lasko in-plug mini-fuses are not replaceable.- This is a wider (4 3/4") and thus fairly STABLE fan enclosure compared to some of their models.- Should be mostly the same as 3721, except this has the blue logo.E - Lasko 3721- Circular grill, blue speed dial.- Fan speed dial is on TOP.- Lasko promotes this as their fan of choice to PUT IN A WINDOW because it is more RAIN RESISTANT (not weatherproof).- All Lasko in-plug mini-fuses are not replaceable.- This is a wider (4 3/4") and thus fairly STABLE fan enclosure compared to some of their models.- Should be mostly the same as 3720, except no blue logo.F - Lasko 3723- Circular grill, blue speed dial.- Fan speed dial is on TOP.- Although it physically LOOKS LIKE one, this is NOT one of the rain resistant ones like the 3270/3721 (larger size, blue dial, etc.
We moved my daughter into her college dorm over the weekend and since she is a freshman, the dorm isn't air-conditioned. I had purchased this fan due to the weather proofing since I wanted it to be able to remain in the window and on while she was gone during the day and not have to worry about it being damaged by the elements.This was the first thing that went into the room that morning and we kept it on as we were unloading, setting everything up, and putting everything away. The room remained amazingly comfortable throughout the day.
With this kind of use, I've sort of expected something to go wrong or burn out, but nothing has. All I've had to do is turn it on, turn it off, and clean it every four or five months - a fifteen minute chore.As I was writing this, I got to wondering just what my use actually amounted to. Based on very conservative estimates, I figure my fan has run about 3700 hours each year, or about 12,200 hours since I bought it. Impressive as that figure is, get this - since the fan runs at 635 RPM on the low setting, that means the fan's motor, bearing, and blade have revolved over 460 million times and still counting!
).- All Lasko in-plug mini-fuses are not replaceable.- This is a wider (4 3/4") and thus fairly STABLE fan enclosure compared to some of their models.- LOOKS just like the 3721, larger enclosure and no blue logo. But again not a rain resistant model.- NEGATIVE: Rattles a little at all speedsG - Lasko 3733- Simple grid grill.- Fan speed dial is on TOP.- All Lasko in-plug mini-fuses are not replaceable.- NEGATIVE: Shakes a lot at settings 2&3.- NEGATIVE: Listeners thought the hum tone was more annoying than the others.H - Lasko B20201- Simple grid grill.- Fan speed dial is on TOP.- All Lasko in-plug mini-fuses are not replaceable.- NEGATIVE: LOUD at highest setting, listeners thought annoyingly so.- NEGATIVE: Little more of an airplane hum/whine sound.
If a little additional on-going expense for a fan makes this much less costly alternative to air conditioning more palatable, then that's probably a good investment.However, being green is an important factor for some folks, so here below is a comparison in electricity usage I measured.

Review sites cannot get anywhere near a statistically valid user sample, so although we learn from comments about DEFECTS and EARLY FAILURE, I suggest not filtering out a model based entirely on them.There are also old reviews that have already been acted on by manufacturers to improve the product or fix a description, thus the review may no longer be accurate.That said, defect and early failure comments with details are great for FEEDBACK TO THE MANUFACTURER (or author) and to help us all much more quickly SPOT SIMILAR ISSUES and thus get an exchange while it is quick and easy to do.
great white noise for out in the hallway and moves a lot of air. Good product. The lowest setting is nice and quiet too.
I haven't had it very long, so I can't comment on durability but there are a few things I was specifically looking for when I searched for days before I bought this one, and I got each of them:1. It fits perfectly up against my window, right on the ledge, keeping it out of the way of the machines in my workout room.2. It is very quiet on the low setting (noisier on the high, but it sounds more like wind than motor, if you know what I mean).3.
Answer: no
