$649 Dyson Fan vs. $15 Walmart Fan: The Hard Truth

When I was young, I was a little obsessed with how cool Dyson fans were. But are they actually worth that amount of money? In this relatively silly video, I'm going to compare it to my $15 Walmart fan with wind speed and sound level tests!

Dyson fan looks cool. Ordinary fan makes cool.

[FenderTelecast]

Always thought the Dyson fans looked cool but always wondered about how efficient they were as fans

[quintiax]

"The fifteen dollar Walmart fan had wind speeds of 6.5 miles/h at 3 feet and 5.1 miles/h at 6 feet."
Me, an European: Hmmm, interesting, no clue what it means, but suck it Dyson boi."

[MayankSharmaTheAtheist]

This is one of those tests that highlight the fact that more expensive doesn't always mean better

[googlestolemyhandle]

Would have been interesting to see the wattage used on each one throughout the settings.

This is a GREAT review, and proof that just because it looks cooler and costs more money doesn't mean it's better. We got our Dyson Pure Hot + Cool because it did everything (heating, cooling and air purification) - and got it at Costco for almost half the price of what it retails for. So it was a more worthwhile (albeit still overpriced) investment. It's come in handy when the office gets a little colder in the winter than the rest of the apartment, and I wouldn't trade it for the world now as it starts getting warmer and my pcs, and what have you warm up the room even quicker. But again, although I'm happy with it overall, it doesn't mean you can't get numerous products that do all these things separately for much cheaper, and just swap them out throughout the year.

$650 Dyson fan VS $15 walmart fan.
Me: Just buy $200 AC that actually cooling your room.

[timothyxxxpaul]

I bought a $50 fan that sits on the ground and you just basically swivel it up or down. That thing is so damn powerful and even on the lowest setting it sounds like a industrial fan. It will instantly cool you off but you just just have to endure the jet engine is has for a motor lmao

I always wondered why people praised the Dyson. My friends and I designed a fan last year for our group Engineering project (I'm an aerospace student), and we found out during the development that the Dyson design was quite inefficient

In an effort to stop people from all commenting the same thing, here's a list of frequently commented things and my response to them:

*Comment:* You're comparing an Air Purifier to a fan. That's like comparing an apple to an orange.

*Comment:* The Dyson will last much longer as it has a brushless motor.
*Response:* True. But you could buy several cheap fans and replace them as they wear out and still have saved hundreds of dollars.

*Comment:* A 10dB difference is ten times louder in a technical sense, but humans don't perceive that large of a difference.
*Response:* Also true. We perceive it to be about twice as loud. But that's still significantly louder than the cheap fan.

*Comment:* You should have compared the cheap fan with the AM07 Dyson fan that doesn't have a HEPA filter restricting its air flow.
*Response:* This was the only fan at my local store, so it was the one I tested. I think the point I was trying to make about the efficacy of this particular Dyson fan still stands, but if Dyson is confident that one of their other fans is able to beat up some cheap fans in a wind speed test, they can send over one and I'll shoot another video with more tests.

The wind speed is different as the airflow is evenly spread out compared to the Walmart fan at it flows on one spot

[campitcher]

Got one of these from Costco. Returned it after a few months. We hated it. Dyson products are insanely overpriced and usually don't last long. Every dyson product I've had has broken. Had bad air flow out of the box. The filters on our fan clogged up before they were supposed to be replaced and then the air would barely flow at all. The filter replacements are also 80 bucks a pop.

[PhathizweMalinga]

What a great video, I bought a Dyson fan about 6 years ago becuase it was on special. I drove home plugged it, unplugged it, drove back and returned it… finally understanding why it was on special. It was R5000 at half price at the time, and I bought a replacement fan, for R600… I still have my El Cheapo, works like a charm and have never even changed the batteries on the remote…. It is unfortunate because I wanted to need the Dyson :-)

[bwbadger]

Nice analysis. I wonder, did you also measure what air *volume* is moved by each fan vs air *speed*? Do you think there is there any practical difference between volume vs. speed?

[asadfarraj]

I just found out that there's a different type of fan than that bladed one. Basically I'm poor.

Where's the table lamp guy? His request is close.

[leeclinkscales]

A change of 10 db does indicate 10 times the power, but humans do not perceive that as 10 times the volume. For practical purposes, a change of 1 db is approximately the smallest perceptible change in sound volume. It takes doubling amplifier power to raise speaker volume by about 3 db. To produce an apparent doubling of volume, the amplifier power must be multiplied by 10.

[vincentrobinette]

One more comparison to make: Plug them into a watt meter, and I'll bet you'll find, that the Dyson "Air Multiplier" will use more power per CFM of air flow. Again, that difference in power will probably be less, than powering up both the conventional fan AND an air purifier. The Dyson might actually be more efficient than running both other less expensive units. Note, that for every watt consumed by ANY electrical appliance, there is ~3.4 BTU's of heat dissipated. The less power your air circulating equipment uses, the less temperature rise in the room!

[MagFlux]

Can confirm these results. I have one and continue to use it because I enjoy the technology it has (really wanted something with env info and voice controls) but when it comes to its core purpose itself, it’s honestly crap as a fan. It’s significantly louder and moves less air than my much cheaper Honeywell stick fan does.

[G-J-]

I own one and yes in the beginning i was surprised how much more powerful my old fan was but after using it for a couple months realized that for some odd reason, the air that it blows feels somewhat cooler than the old fan and the fact that you have such a large range of speeds, it makes it so nice to have nice cool air blow at you so quietly and still keep you pretty damn cool. Older fans would just feel exactly the same regardless of which speed u used. So for me its amazing and i love it. Not to mention all the features and wireless control and air filtration

Bought one of the original back in 2009 and it still works to this day.
