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…

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 eventually reach my purifier.

My previous experience with a purifier was a Honeywell tower that didn't move air. I noticed an improvement when I switched to a unit that moves air better.

Am I wrong? Should I give up Dyson anyway and choose another product?

Yea, it's weird reading this thread to me. I have a cordless Dyson vacuum and it is by far the best home vacuum I have ever used, both in terms of suction power (even compared to non-cordless ones) and in terms of other usability/features.

We must have had a dud as we got the Dyson animal hair one and it was terrible. Battery life was rubbish, the suction was crappy and the pick up just wasn't that good. Ended up getting a gtech which was fine for 2 adults in a small 2 bed house with wooden floors, but now we have kids and a bigger place we got a Shark corded and it is amazing. Literally the best vacuum we've ever owned.

I'm not sure the cordless Dyson I have compares well to a good corded vacuum cleaner for cleaning power. But for me, I got one a couple of years ago (after thinking about getting a Roomba for the umpteenth time and concluding it wasn't for me) and it's been perfect for my use case. I normally have a housekeeper come by once a month. But the high traffic areas including the kitchen really need a quick vacuum now and then in between cleanings and the Dyson's been perfect for that. I hated having to haul my corded vacuum out to do this. (So I mostly didn't.) Now it's literally a couple minutes work to grab the Dyson and give a quick cleanup.

Those bathroom hand dryers do spread bacteria around at an alarming rate: https://www.health.harvard.edu/blog/the-bacterial-horror-of-...

> the researchers attached high-efficiency particulate air (HEPA) filters to the dryers, which would eliminate most of the bacteria from the air passing through the dryer. As I recall, one of the selling features of the Dyson Airblade is that it has a HEPA filter built-in.

On the output?

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?

For a "wired" vaccum, i'll go with Festool every time, but yeah, Dyson wireless vacuum are pretty good.

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 hated the vacuums (the one I bought was way too heavy, loud, expensive for what it did) and air blades, but love the fanless ventilators. It’s light, cute, easy to move, with no visible moving parts, is still surviving spotlessly. I wish there was better competitors.

Dyson is about design (art) not practicality. You want a boxy filter that works well, go right ahead. But some people don't want that in their living space.

Ideally they could be beautiful, and clean properly. You can't win them all.

If Dyson had to choose one product to keep making, but discontinue all others, it should be the V11 vacuum. Runs forever and cleans very well. All their other shit can kick rocks.

15 x 7% = 105%

Obviously that's not how those numbers work, but you get the idea: it's not necessary to filter all the air at once.

"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 ap…

It's the same guy from this video [1].

Yeah, the gtech was a battery vacuum too, but placed the motor/impeller right next to the entrance of the device, no long pole. I wanted to love the Dyson because of what we paid for it, but I left me a bit meh. My folks have a corded Dyson now and it is a good machine, but I really feel the shark just wins. Man I am dull :p
