I 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…

The idea is that the fan is deployed in a closed room and over time, all the air in the room will be circulated through the filter.

Technology Connections did an episode on air humidifiers a while ago: https://www.youtube.com/watch?v=oHeehYYgl28 The fan and filter size matter the most. Most of these things are hugely overpriced for what they are.

After watching his dishwasher episode I lost all respect for him. He clearly forced that episode and his conclusions were predetermined so he could have a clickbait video title/theme.

Can you elaborate? That episode really worked for me, and fit with my own experience of dishwashers and adding pre wash. My latest machine doesn't have a prewash holder, but does have a prewash cycle on the eco setting - which cleans fine for the majority of my needs - but if things are filthy I through some bicarb in to the machine before I turn it on and it is awesome.

"Marketplace took its results and questions to Dyson engineer David Hill at the company's headquarters in Malmesbury, England.

"We are, we think, delivering quite a good value proposition for the consumer," he said, stressing that Dyson purifiers can sense pollutants in the air as well as capture them, and also provide strong air projection."

I just want to point out the above: Along with the picture, it gives the appearance that a reporter waited outside of a Dyson office and started interviewing an engineer.

I've literally never seen a piece like this where the company's PR department ALLOWED an engineer to be interviewed.

I certainly hope Mr. Hill didn't get in big trouble for this. At my company, if I speak to a reporter without explicit permission from legal, I'm a goner immediately.

I think Dyson is the best example that shows marketing really works. I've yet to find a single Dyson product of quality. Their vacuums are downright terrible.

I'm surprised to hear that sentiment about the vacuums in particular! I found the v11 I bought to be vastly better than previous vacuums I've owned, with excellent power despite being cordless, really light and much much quieter. I haven't used any other Dyson products; I opted to buy Rabbit air purifiers over a Dyson Air.

Miele. Every Miele I've found is superior, hands down, to its Dyson equivalent.

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. I know James Dyson is regarded as a genius engineer, but the consumer product company bearing his name seems to be 99% m…

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.

Miele. They last forever and are much cleaner, lighter, and more powerful than equivalent Dysons.

I've had a good experience with a Shark vacuum. It had high ratings from Consumer Reports. I bought one and found it did a great job with heavy carpet and rugs, and wood floors. It is easy to take apart, clean, etc.

I have a Shark also, sub £200 (£170 i think), pretty sure a similar Dyson was easily twice the price. It is quite, light (its one of the hand held models) and certainly powerful enough for general use around the house.

I have tired this with an air quality sensor (measuring VOC, PM2.5, and PM10) and found doing this method I had a huge increase in PM2.5 compared to baseline levels (1-2 to 100-280), so I imagine this method would only work well if you have distilled water. I would also be worried about bacteria and mold.

But isn't using a fan too long in an enclosed room dangerous?

I’m getting ready to hop into some meetings, so here is the short version, I can elaborate more later today.

So he only measured cleaning results after the pre wash cycle and not after the full cycle. Obviously you would expect a short wash with soap to be better than a short wash without. And the results there were a lot closer than I would have expected.

He completely ignored final results while opining that dishwasher tabs aren’t effective without actually testing them side by side.

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]"
