In Australia, Kmart has a house-brand bladeless fan for AUD$89. The Dyson full-sized bladeless fans cost $600-$800. The reviews of the Kmart cheapo one are very positive, both from customers and review publications. We bought one for the baby's room and it's been great so far. It also doubles as a white noise generator.

That's a name I haven't heard in a long while. K-Mart was always one of those stories of going to live on a farm upstate. Now, I know that it actually went to live in a land down under.

The public bathroom air blades drive me crazy. It keeps splashing the water back and forth, the air speed is too high and my hands inadvertently touch the sides and probably there are a bunch of germs circulating inside, as not everyone washes their hands thoroughly. The old school super blowers that just do hot air down, or whichever direction you turn, probably consume more power, but certainly dry my hands faster…

Protip: If you're in a public rest room and there are two hand dryers next to each other, use them both at the same time. One for each hand. Much faster.

Further Protip: Wipe your hands on your jeans.

Unless I'm at the library or a Starbucks, I generally don't wear the kind of clothes in public that one wipes hands on.

For recurring revenue… selling only the fan, you get one sale and you’re done. Selling the fan but with a filter unit, some subset of customers will replace the filter every 6 months as “recommended” and you have recurring revenue on that fan forever.

Dyson filters aren't consumables. You wash them out and reuse them.

Then I imagine part of it is the fact that people are willing to spend $x on a fan (of any sort) and $x+y on an air purifier.

If an air purifier is generally accepted to be a higher-price item, then making a fan into one with some sort of filter helps justify the higher price.

(Just speculation, though. I have no info about their design or marketing decisions.)

Reminds me of newer appliances (such as washing machines/toilets) that brag about water efficiency yet don't do nearly as good a job, requiring a second cycle, thus using more water.

In at least some cases, the greater nominal efficiency may be required by regulations.

To the downvoters on wincy's comment: please let's not downvote people for asking questions, or just because you believe they are misinformed -- that's what replies are for.

You shouldn't downvote people for asking questions, but asking a question and supporting it with a link that tells you the answer is fair game, especially when your "question" is an argument hidden behind a question mark, and the link disproves that argument. There is, of course, the possibility that wincy's comment was meant to be tongue-in-cheek, though. I personally can't quite tell which way it was meant.

I guess I was being charitable, and imagining that the poster might be a Korean of a certain age where this myth held weight. The article suggests that young Koreans have changed attitudes, but that doesn't mean that everyone has. I think the comment replies to his question did a fine job challenging the myth. Obviously it's just my opinion, but I'd rather save downvotes for people who were clearly trolling or maliciously off-topic (and I don't see that here).

I live in a large loft-style apartment on two floors which is actually a large room. There are only a few windows and they are placed in a way that no air draft gets created. When I bought a purifier, one of the things I was looking for was air movement. I position my Dyson so that there's a draft throughout the apartment. I thought this would improve the air filtration because the air would move through my home and…

My issue is the cost. My local costco has these units in store for $800 USD. Further down the isle they have oscillating tower fans for $30, and smart air filters for $100. I bought two pairs of each before winter. The fans are quiet, have plenty of control options, and non-volatle memory so you can use them with smart plugs. The air purifiers are 4 stage, with active charcoal and a long life (6 mo, 20$) hepa filter.…

Dyson, like Apple, doesn’t make products for nerds like us who are willing to go through that level of effort. Their prices are high because their products are simple and “just work” without much fiddling.

Are they? We have a modern unit (with the 2 stage filter), adn they send a notification when you have to buy a new one, for $99 CAD

Dyson : Air Products :: Beats : Audio Products Pretty much every Dyson product I've used, from the public bathroom air "blades" to the vacuums, seem like a gimmicky, inferior products with a premium price tag. None of them do their intended job better than older, cheaper products in their category.

Pretty much every Dyson product I've used, from the public bathroom air "blades" to the vacuums, seem like a gimmicky, inferior products with a premium price tag That's interesting to me because I've had the opposite experience. I move a lot. For almost decade I moved twice a year. I don't like taking the dirt from one place to the next, so I buy a new vacuum cleaner every time. So I've been though a lot of vacuum cl…

I like Vacuum Wars as he provide fun reviews

No. This is yet another urban myth. "Despite no concrete evidence to support the concept, belief in fan death persists to this day in Korea,[further explanation needed] and also to a lesser extent in Japan.[1][2][3]"

The wiki page links to the EPA which does advise against fans in a closed room when it is over 90F: Don't Use a portable electric fan in a closed room without windows or doors open to the outside. ... Don't Use a portable electric fan to blow extremely hot air on yourself. This can accelerate the risk of heat exhaustion. ... Don't direct the flow of portable electric fans toward yourself when room temperature is hott…

That one's interesting in part because South Korea mostly doesn't get that hot. (Summer highs seem to be mid-80s Fahrenheit.)

Looking at climate data for the country, I was struck by how similar it is to upper Missouri. Saint Louis is about as humid, but a bit hotter on average. Which would make me suspect that if "fan death" was a thing, we'd be seeing it in a band of US States that're similarly hot and humid.

Speculative difference would be if air conditioning is really uncommon in South Korea, but presumably we could even that out by comparing to poorer people in the US.
