Check out AvE’s tear down of a $500 Dyson hair dryer.[1] He was expecting to ridicule it but was instead blown away by the engineering - tiny high torque zinc cast brushless DC motor, CNC-milled impeller, etc. It’s a good watch, including FLIR performance analysis, Fourier analysis of bearing noise, and more. In summary it’s definitely more engineering porn / extreme overkill than marketing bs. [1] https://youtu.be/j…

That video you linked is absolutely solid. Learned a tonne watching it. Never woulda thought 45 minutes about hair dryers would be so great. That dude is awesome.

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…

AMA from a vacuum technician: https://old.reddit.com/r/IAmA/comments/7gmsoe/iama_reddits_o...

IIRC he recommends Miele vacuums.

It's obviously popular to hate on silly-expensive tech, but these quotes were telling for me: > "I think what we're trying to do is pull back a little bit from the CADR metric," he said.

I'm also a little suspicious of relying entirely on the CADR metric. If you're running a filter in an environment that's constantly producing particulates and you need to filter large volumes of air, it seems useful. If you're about to walk into a smoke filled room and have 25 minutes to clean the air first, there's no question that CADR is king. I think it would be interesting to run a purifier in a normal house for…

I'm more worried about the random friend who drops by. Sure we wear a mask, but when can we take it off when they are gone?

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…

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.

On a vaccum they are washable, on my tower fan they're replacable.

I ordered some from china (probably fake) for $30 rather than the $100 dyson wanted.

We have four in our house and they are workhorses. Still running strong and quiet 3-4 years later of running 24/7. Probably one of the best things I've ever bought. They are also popular enough, and have been around long enough, that there is an "ecosystem" of third party replacement filters that are affordable and capable. The sound of the Coway is also quite nice for sleeping in our opinion. It's a quiet "whoooosh"…

What benefits do you feel from having four filters? Not hating, genuinely curious. It's just never occurred to me to filter the air in my home aside from burning something on the stove or similar

It's not a necessity if you have the window open to move around the air, but that's typically not as much of an option in the winter. You'd be surprised how much dust and particles a purifier picks up.

If you take a look at the photos for the Blue Air 211 on Amazon, you can see how much it picks up. Mine was exactly like the photos. The pre-filter was completely covered in dust, and the inner filter was completely dark after 6 months of use.

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

Wow, they have a payment plan for the filters.

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 malici…

To be clear, I didn't downvote their comment — I don't think it warranted it — I'm just saying I can sympathise with the argument that a comment that doesn't add anything useful to the discussion is a fair target for a downvote.

Saying "But what about x?" when you yourself provide a link that says that X is a non-issue doesn't make for an engaging discussion. "But what about x? This link suggests it's not a problem but I think it is because of y" does make for an engaging discussion, even if y is seemingly nonsense.

I prefer the Excel XLERATOR hand dryers, and usually spec them over most other models. Hands dry in ~10 seconds, not spashing onto a lower surface, etc.

Ditto. They dry my hands much faster than the Dyson and I don't have to touch a germ infested surface.

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.

I did recently buy a HE washer to replace the junker that came with the house. It may just be that I live a (mostly) white collar lifestyle, but I do make a mess of clothes I wear for renovation and yard work or for camping. So far, the new washer hasn't given me any issues with getting things clean. The only adjustment I had to make was learning to use much less detergent than I was used to. There are also just two…

HE washing machines seems to be one of the few things where less water is still ok. They make up for it by running longer. A water efficient toilet just ends up not working as well because it’s using less water and not reusing it (like washing machines).
