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…

It sounds like you're using the Dyson as a fan and something else as the actual purifier. Sounds like that setup works great for you, but it does prove the point that the Dyson is a fan, not a purifier.

My previous experience was with a Honeywell tower but I do not have the device in my apartment anymore.

What I am describing is that the Dyson ends up doing a better job alone than the Honeywell did. Especially when it comes to the second floor. However, as you said one could quite likely achieve the same result with any air purifier and a strong fan.

I'm not a fan of Dyson products, but i really like their air purifier (with heat). I'm not that concerned with performance as I'm just trying to maintain clean air, not actively clean it. It's quiet, has an actual thermostat (instead of the 0-10 knob). No burning smell and hot air temperature isn't a fire hazard (great for clumsy kids). Best of all, it looks nice. That said, I don't think I'd be willing to pay upward…

"Best of all, it looks nice." The Dyson USP.

:). This is why we have terms like "Wife Acceptance Factor" and "Happy wife, happy life"

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…

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?

Seriously, the Dyson cordless is one of the best investments I've made. Having the charging station hang on the wall means it takes up no space that I was previously using.

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 think its a good quality fan and a fan heater that also purifies. Purification isn't its only goal, so if you care only about that just get a purifier. Presumably the cheap DIY box did a bad job at heating the air.

I love the public bathroom Dyson thingies. They kinda became a standard for me now, love how quickly they dry hands. Way better than paper, towels or weak fans. But yeah, the other stuff is a bit gimmicky.

I'm glad they changed it from "insert your hands between two blades of air" to "put your hands under ONE blade." The old design would just push your hands into one side or the other, where the bacteria-laced water from the last person still remained.

I don't understand comments like this, I have never had a problem not touching the sides.

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]"

I have worked night shift for 30 years. I sleep with a box fan in my bedroom with the door shut to filter out noise. Works really well.

I think Dyson benefits from the same effect as Apple/Tesla/Beats/etc. Their products are good but their triumph is upselling. Dyson cordless vacuums are like $800+, was your previous one that expensive?

My dyson cordless vaccum (v7) was 399$ (CAD) so it was not insanely expensive and I would not go back. Their tech can probably be imitated at a lower cost, but I won't take chances with the cheaper knockoffs, the tradeoff is not worth it.

Is there a Dyson-equivalent cordless vacuum that goes for less than $200?

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?

You have to make sure the filter is HEPA, and calculate whether the device has had the time to do a full air change given the room size and its CADR rating.

Viruses are generally too small for even the best filters, but the droplets that carry them are well within what a HEPA filter can manage.

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.

I am sort of worried that a lot of internet sentiments go back to just one person. I also have a vaguely negative impression of Dyson, and realized it came from that same Reddit thread. It feels like every internet community just recycles information from previous threads and only rarely gets input from reality.

FWIW, I have a Dyson wireless handheld vacuum. It's pretty good, but I can't way if it's worth the price.
