Last year I bought an air purifier for ~800, but PLN ($1 = 3,7129 PLN at the time of writing) to deal with the Polish winter - already swapped out the HEPA and carbon filter(At a CADR of 300m3/h I think the price/value ratio is decent, as opposed to whatever Dyson is trying to con people into buying.

#112The cobbled together box fan may work better than a Dyson, but my wife isn't going to let me put a cobbled together box fan in the library.
People care about aesthetics. There are entire industries built around this, even in technical areas (industrial design, UX, etc...)
So the Dyson wins simply because it will exist in the house and clean a portion of the air, while the Sanford and Son rig won't be in the house and will clean zero air.

I currently use dyson v11 cordless vaccum. I am in the market for a new one, what do you recommend instead ? Price is not too much of concern for me ATM.
I really like my Miele canister vacuum. It's light, quiet, and powerful. I find bagless vacuums, including Dyson's, to be a pain in the butt to clean by comparison. However Miele is certainly not a good value brand either. I've never used a cordless vacuum, but I find the concept suspect for basic physics reasons. You're either giving up weight, power, or both compared to something you can plug into a wall.
Even if you are giving something up for cordless--and I'm happy to stipulate you may be to some degree, there are a lot of situations where you want to do a quick touchup, clean up a spill, etc. and a cordless vacuum like a Dyson is so much quicker and easier. It's the same with a lot of battery-powered tools. They may not be quite as powerful as a corded or gasoline version but they're increasingly powerful enough, especially for relatively light duty use, and they're a lot more convenient.

#114After watching this segment, I immediately bought a 20" box fan, a 20x20 MERV 11 filter, and put one together. It kicks the pants off of air purifiers twice the price and it moves a lot of air through. Best investment ever. CBC was testing CADR, which is one metric among others, but an important one if you're looking to clean a room's air, fast.
I've had one of these for years with MERV10-12 (depending on availability) filters. This is in addition to the 20x25 filter in the central unit. Judging by how dirty the filter on the box fan gets, it is amazing how the central unit is just unable to do an adequate job.

But isn't using a fan too long in an enclosed room dangerous? https://en.wikipedia.org/wiki/Fan_death
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 hotter than 90 °F."

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.

Interesting since the cordless vacuum (dyson v11) I use at home seem to work really well. The previous big corded model we had (Dyson DC33) was also built like a tank and served for almost 10 years before being passed on and still works so maybe I bought into marketing or maybe just different people have different experiences with Dyson products?
> and served for almost 10 years before being passed on Wait what, is ten years supposed to be a good lifetime for vacuum cleaners?
I'd say with couple of times a week usage for a thing made out of plastic I could expect a lot more troubles than it had.
It did require one dyson service which they kindly provide even for old devices and one this pipe thingy swap since it ripped.
But as other commenter pointed out - it still works we just wanted to move on to something smaller and cordless and we expect the first thing that will fail in V11 is going to be batteries because other than that they're really sturdly built.

#118I still cannot get over this product. They whole selling point of a dyson fan is the 'air multiplier' tech, which creates a low pressure zone that propels air through the ring. According to dyson, this tech can move 15x more air than the fan in the base of the unit. Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? https://www.jameco.com/Jamec…
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.

> Why in the world would you build an air filter around a system that does not directly interact with 93% of the air it moves? Dyson fans produce a continuous stream of air. Regular fans produce choppy air. I don't think anyone actually notices this effect until you point it out though.
And, in my experience, a lot of noise. Way more than a regular fan for the same perceived amount of air flow.

#120Dyson : 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. I know James Dyson is regarded as a genius engineer, but the consumer product company bearing his name seems to be 99% m…
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…
It reminds me of a less-extreme version of Juicero. They made a $700 WiFi-connected "juicer" that squeezed bags of juice using QR codes to scan the bags and then a custom power supply, custom machined gears, and a custom 15A 330V DC motor to actuate a press to squeeze the bags between two metal plates. Of course, a roller could have done it for a fraction of the price, or you could have just let gravity pour the juice and not even need a $700 machine.
Dyson's very into moving air in creative ways and blowing through holes. They definitely seem to be the best at it and are very good at it, but they're just playing with an artificial constraint. No one says you have to be able to see through your hair dryer or air purifier. You could make much more effective or cheaper products without those constraints. Just people think they look cool, so they're willing to pay a premium for the weird, "futuristic" Dyson product over the boring normal product. That does make it seem like largely marketing though.
