610DC Energy Smart Air Circulator Fan with Variable Speed Control, DC Motor, Adjustable Head, Quiet Fan for Bedroom, Office, Home

I had doubts about spending this much for a fan, but would say it has been worth it. The variable speed control lets you adjust all the way down to completely silent, while still getting a nice mild breeze. It also lets you turn it up high power when needed, or to fine tune it to the level of noise that doesn't bother you anymore. The cord "feels" a little short at times, as the DC power supply in the middle needs to sit on something to support it. The smaller DC cord from the power supply to the fan seems like it might be a little fragile, or that the connector at the end may be susceptible to damage, but mine is doing just fine, despite how it looks. It really does hold a nice column of air. letting you "shoot" the air for a longer distance. I would judge the Vornado claims as 30% hype and 70% truth, which is pretty good in my book. I was expecting higher ratio of hype, given their glowing claims. I can confirm the lower power draw for this DC fan. It is most noticeable at the lower settings, where I can still get a decent breeze on just 2 or 3 Watts, instead of getting a wimpy breeze for 15 or 20W from my other fans on their lowest settings. The savings are less pronounced at full power, but it still draws about 30% less that any other fan I have in the house for an equivalent breeze. I expect it will take about 7 years for the energy savings to pay for the price difference, but the infinitely variable speed by itself is almost worth the price difference. I find myself gong over to nudge the speed up a little or down a little several time a day. There's definitely something to be said for infinite speed control (and basically infinite noise control). Two or three speeds for a fan is very crude by comparison. If it's just a little too loud, I turn it down just a little. If it is just not quite enough air flow, I just turn it up a little. No more choosing between too little air or full-blown hurricane any more. It can be as quiet as I want it to be, or blow just as hard as I want it, or anywhere in-between. I got it to be "greener" and save energy, and because I enjoy "quality" stuff over throw-away stuff. This fills the bill on both counts, and the improved performance over my old fans is a very nice bonus feature. No quality problems so far, it has held up to me kicking it over in the dark a few times (too quiet to notice in the dark, but light enough to not hurt my toes too badly), and it is balanced nearly to perfection, so runs very smoothly. It still feels expensive, but is maybe worth it, or at least worth a good portion of the extra cost. I'm not ready to spend that much for all of my fans yet, but getting one of these for my highest usage fan has worked out well.

Al inicio pensé que era demasiado pequeño para poder mejorar la frescura en una habitación calurosa pero hace lo suyo. Recomiendo utilizar la máxima velocidad e ir reduciendo, según como se vaya resfrescando.

Superior indoor ventilation. Positioning this fan as recommended really works. You get air movement throughout the room but no localized blast. This is much more comfortable for sleeping, for example, than fans which blow on you directly, or wave a column of wind from side to side. It gets noisy at high speed. This problem is solved by getting one that is not too small, and running it at lower speed. Optimal noise, and breeze, is reached with the model I bought, which boasts continuously variable speed. This optimization comes at a price, however. Much as I like this fan, I have to call it expensive. If you had a variac ( a variable AC transformer ) sitting around doing nothing, maybe you could use it on a fixed-speed model and get finer speed adjustment.

In our area it can get quite warm in the summer, so I bought this fan (the "610DC - Energy Smart" version) for our bedroom to give us a breeze at night. I am very sensitive to noise, even the continuous hum of a fan, so having a low-noise fan in the bedroom is very important to me and I am happy to say that this fan doe not disappoint. Yes, on the highest setting it is louder than I could tolerate, but the fan has a completely variable speed control, so I can dial the speed and noise in to exactly the level that works for me. The fan uses a DC motor and thus it is much more energy-efficient than my old Vornado fan with an AC motor. Overall I am very pleased with this fan. I wish it was less expensive, but I suppose you get what you pay for, at least in this case.

I have a sound studio in the attic of my home, so you know two things: it gets HOT up there in summer, and I am very attuned of noise levels. My central air barely reaches up there, and I can't have a portable or window air conditioner up there due to the sound. Thankfully, I found these fans. They are honestly, the quietest I have ever seen. For those that care, I measured the dBs - at about a 1/3 power, this puppy gives off a measly 5dBs of noise. At about 2/3 power, it climbs to about 20 dBs. Finally, at full power, it's around 35 dBs (most of that is the actual air moving, rather than the motor). While it does get louder at the higher end of it's power scale, the good thing is I don't think I've ever used it higher than about 1/2 power. Even at low levels, it really moves the air efficiently and evenly (for a medium-sized room). The one negative note I will say, is the "small" version of this fan isn't worth it. It's somehow louder than this medium size, so for the price, go for this bigger version - it will move more air and is overall quieter. I haven't tried the $500 large size version, as for $200, this one is good enough for me. I have bought two of them, which is enough for the entire top floor of my house. Yes, they're expensive, but if noise level is important to you, these are worth every dime!
