I am now on my fourth Vornado brand fan in the house - I have had them for nearly 10 years, and have found them to be long-term reliable and probably the best fans I've ever owned.
Vornado makes quite a variety of fans, ranging from industrial models that you can put in a garage (which I have), down to smaller kitchen fans that are a bit louder but still put out just as much airflow as the more powerful models.
Two of my Goodman GSC130181 Air Conditioner SEER ave run 24 hours a day for more than 3 years, with regular cleaning of the grill and air intake. So as far as brand value and quality, you can't get much better.
This specific 630B 3-speed fan is one of their mid-size models. It sits firmly on the floor with a large base, and the control knob is conveniently located on the side of base to fan arm. There are only three speed levels on this fan, vs. some of their other models that feature a steady dial giving you complete flexibility from off to high.
If I had to give this fan a "noise rating" - the low setting is completely unnoticeable after a few minutes and blends into the background - this is the setting I leave it on 24-hours a day. But if you want to move air rapidly, just move it up to medium or high and the noise level increases moderately (but I don't leave it on that setting after I have the temp where I want it).
For home use I recommend pointing this fan into areas where the a/c or furnace might not have the best coverage. You can save a lot of energy in heating/cooling your home due to the distance these fans can move air. Down a long hallway you can feel a strong blast of wind from this fan even on the lowest setting.
Highly recommended Goodman Air Conditioners - don't be afraid of the price, because you're going to have this fan for a long time to come with minimal cleaning. Snapping the front and back grill off is easy, and you can just vacuum out the dust that will gather after prolonged use. All four of my Vornados have lasted a minimum of 4 years with almost constant use, even in very dusty (garage) conditions.

Honeywell Compact Purifier Permanent HHT 011
When I first purchased the Honeywell Compact Purifier Permanent HHT 011 I was ecstatic at the thought that allergens,
dust and other air contaminants would be filtered, especially for the
price. My room is extremely dusty so I needed some sort of solution and
I hoped that this was it.
For the first six months the purifier worked efficiently, or seemingly so. I ran the it, as recommended, 24 hours a day nonstop. When I'm not home I ran it on the high setting (there are three settings), medium when I was around and low when I slept. I cleaned both the outer filter and inner HEPA Air Purifiers regularly as a lot of contaminants were being filtered. I noticed a somewhat significant difference in the air quality of my room (11.5 x 8 ft) during this span.
After sixth months the purifier was rendered useless and actually made the air quality worse. The contaminant intake became less and less, the dust in my room begun accumulating faster (I still dust frequently) and the purifier's fan was blowing out unclean air - air that reeked heavily of dust.
I highly doubt that the HEPA filter is efficient forever and needs no replacement. It is charcoal grey and transmits little light when held to a light source (not sure if this is significant as compared to a car air filter test). I do as the manual suggests and vacuum it (more frequently than recommended) and I vacuum/wash the outer filter regularly. Another review mentioned that the purifier became filled with dust and grime over time; the same thing happened to mine, as evidenced when looking down the air vent. I tried to clean it out by blasting 180+ PSI of air with my air compressor, but it did nothing to help. The dust was very thick, almost lint like, and would not budge at all.
To make matters worse the purifier is fastened together by hexagonal security screws (I'm sure the average household does not have the required screwdriver). I recently bought the screwdriver and opened the purifier to clean it out, and found that the inside was a horrendous mess. Every surface and mechanism was layered with dust. The insides of the tubular fans were coated with dust as well. The task of carefully removing components to access all compartments for dusting was tedious and took some time. I've cleaned almost all of the contaminants from inside the purifier, but I am still very skeptical about using it again in fear that I will have the same problem again, perhaps in less time than before.
To sum it all up, this product was good for about six months until the inside of the purifier became festered with dust, and it was extremely tedious to remove it all. I'm not sure when this accumulation of dust began, or for how long the HEPA filter has been ineffective. The purifier does not filter all contaminants, instead sucking some into the interior and spitting it back into the air in my room.
With all of that being said, there are numerous positive reviews on this product; perhaps I am an unfortunate rare case. For the price I'd say it is definitely worth a try, but be cautiously optimistic if you decide to make the purchase.

SF 609 Portable Evaporative Cooler Ionizer
I use this SF 609 Portable Evaporative Cooler Ionizer in my home in Phoenix Arizona in an enclosed room with
very little air circulation. It has kept me from becoming sweating over
the course of the hot spring nights thus far, and that makes it worth
the purchase. It's better than a fan, because a fan wouldn't reduce the
temperature in my personal area like this device seems to. It basically
cancels out the heat emanating from my computer and other devices. So as
a result I don't overheat and am at a neutral sort of "room
temperature" typically. It's not chilly, however. In my circumstances,
at least, it doesn't provide that coldness you would expect from an AC
unit set on 70. So if you have to have that, then I would advise a
normal AC unit over this product. But this does prevent me from becoming
a sweaty mess by the time I want to sleep. And for that reason I'm
happy with it.
If you do use Portable Air Conditioners for say over 5 hours, it will slowly start to build up humidity in a room with little or no ventilation. But even that effect I find to be mild. I've had it go for 7 hours and all I noticed was a very slight dampness on the floor. My computer was fine, and everything electronic was unaffected. It did start to get balmy slowly after that point so I went ahead and opened my window for a bit. But it was only an inconvenience for the many hours of non-sweating it had provided.
My method for draining has simply been to place the unit on the side of my bathtub with one roller hooking onto that ledge, and to lean the other end slightly into the tub, and remove the cap: letting gravity do the rest. This does take a little strength to do, but It's quick and easy. My only complaint about the device is that It's cord is a bit short, about 8 feet long, and only barely reaches to my desk from the necessary socket across my room. Just something notable, but not anything you couldn't work around with an extension cable or something. Make sure to put a lot of ice into it, the instructions don't do justice to how much "2 liters or so" really is in reality! It's a good small buckets worth. That will last all night.
All in all an economic solution to being a sweaty mess in the desert nights.
