It’s also just Dyson’s completely overpriced bullshit. It makes weak air flow and has no real benefit for use as a fan.
Project Farm has tested them a couple different times. They’re expensive aesthetic toys.

Its true there is a fan in the base of all bladeless fans, but the fan is smaller then traditional fan designs and moves the same if not more air then traditional fans.
Air is pulled in through the base and forced through a thin slit. This fast stream of air creates an area of low pressure, drawing in and amplifying surrounding air.
Because air “sticks” to itself, when you get some air moving (by breathing out, for example), the initial bit of air that you move “drags” some air with it from beside and behind. This is what Dyson calls “air multiplier technology”.
Dyson uses this property of air to claim that they only have to move a fraction of air (with the fan in the base) of all the air that blows past you.
Here is a example of how this works, and how you can use one breath to fill a large bag.

A traditional fan also pulls air from around its blades using the same principal. A bladeless is just a gimmick it has no actual benefits.
it has no actual benefits.
Toddler hands don’t go through the protection of a classic fan, if it’s built like after 1965.
Also we were not discussing esthetics but efficiency.
Thank you.
Much like Sharper Image’s Ionic Breeze, this is a very expensive bullshit tower, but I am seeing them everywhere lately. Box fans are fucking amazing. Get a box fan.
Ironically love Lemmy for the explainers you get on a shitpost. Only stumbled on this cause I was looking it up myself. Thanks for the write up :)
Keep in mind, that the explanation is wrong.
Yep, dyson bullshit marketing.
Just like their hoovers then.
Used to have to use one and I just don’t understand the bagless appeal. I like having a bag to contain all this awful dust. Felt like I needed to wash every time I emptied it and they fill up so fast in comparison too.
Sir, this is a Wendy’s shitpost community.
It’s the same reason I use a beef bouillon cube in place of real meat when I feed my vegan friends. It’s much smaller so it doesn’t count.
My god, the sass - it’s magnificent.
Smaller fans = more noise
And why isn’t a regular fan getting the “surrounding air” to move too? Is there a subscription for that?
It’s most probably dyson bullshit (the moved extra air is slowing the original air down, or it’s magic) marketing.
Magnets!
I got one years ago when they still were a lot cheaper and I must say it’s the best one I ever had. It’s powerful and so quiet that I can leave it running next to my bed when it’s hot.
Fans are usually loud in proportion to their speed. Quiet ceiling fans have a big diameter and many blades. Doesn’t a small fan cause a lot of noise?
Honestly depends on speed, quality of bearings and motor, blade geometry and thickness as well as any possible enclosures.
The biggest source of noise with fans is air cavitation.
I just imagined someone turning on a fan and hearing an electric f1 car drive by
i don’t think the point of the post is about being useless or inefficient, but about the misleading name

still a miss-labeling to call them bladeless fans, just because the blades are hidden. by that logic my beef raviolis are vegetarian (tbf: the catholic church made a similar claim during the medieval ages).
Bernoulli Fan is not only more accurate, it also sounds much cooler.

To play devil’s advocate, there are no exposed blades at the point of use. I’d wager people who buy “bladeless” fans are more concerned with aesthetics and avoiding a crying toddler than they are with semantic accuracy. We call Wi-Fi “wireless” even though the router is plugged in.

I can stick my peepee into a bladeless fan and not worry about cuts so there’s that.

well, no, see, you can’t.
you can stick it through it. but you can’t stick it in it.

Regular fans dont have exposed blades either, there is a mesh over it.

I take it you’ve never seen a toddler stick their fingers through the mesh
ToxicWaste@lemmy.cafe 7 hours ago
at work we have expensive fans with a cheap metal mesh around them - to avoid a crying co-worker. at home i have a cheap tower fan with a weird plastic mesh - there are no visible blades on it except if i crank my neck into a really uncomfortable position and shine a flashlight into it. which one of the two can i call bladeless?
luckily i already have a devils advocate and @arctanthrope@lemmy.world dropped the name of god. how well do i need to hide my fans blade to create a Ventilationbescheißerle?

there’s a type of German meat dumplings called Herrgottsbescheißerle, which literally means “little things that bullshit the Lord” for the same reason

Well, Beef comes from cows, and cows only eat vegetation, so beef raviolis are vegetarian. Now, I’m not a Rocket Biologist, but I think the math here is pretty conclusive.

You know … Bernoulli Fan - that’s way better idea than a room full of MBAs from expensive business schools and months of market research and focus groups with 2 way mirrors ever came up with. Well done
