Why wouldn't you just use a cheap fan in place of the Dyson? Sounds like you have a separate purifier that does the cleaning, and all you need is something that will move air.

The only fans I can find that are big enough to move air over two floors make more noise on their low setting than the Dyson's on its high setting. Then there's the issue that the fans would need to be connected to an app in order to power automatically as air quality drops. (I don't have the Honeywell anymore as it was my ex's) This conversation makes me want to buy a second purifier and simply stop purchasing filte…

It sounds like you need a ceiling fan. I have an ADU with a half loft and 26' ceiling over the other half. One decent fan really moves the air.

> I don't like taking the dirt from one place to the next, so I buy a new vacuum cleaner every time. That seems extremely wasteful. Why not just emptying the vacuum cleaner before bringing it to the new place? One person buying 20 new vacuum cleaners in a decade is just one of the reasons this planet is running out of resources.

Especially considering that 80% of the dirt the vacuums collect are his own skin flakes and hair anyway...

Actually, that's supposedly a common misconception[1].

And, in my experience, a lot of noise. Way more than a regular fan for the same perceived amount of air flow.

What? My Dyson fan is incredibly quiet compared to any other fan I've used.

This dispute could be a matter of frequency range. Older ears can't hear high pitch. If the Dyson noise is mostly high pitch, older ears will perceive it as quieter.

I don't diagree with you on some of the Dyson products being gimmicky with a premium price tag, and the air purifier does look suspect to me. However, the Dyson v11 cordless vacuum I just bought is phenomenal.

It has far better suction and cleaning effectiveness than anything I've ever used - which is partly why I bought the v11. Our mains powered central vacuum just wasn't cutting it, and was bothersome to use.

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?

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.

That's weird because the cordless Dyson vacuum we had was utter garbage and my 20 year old Dirt Devil was better in almost every single way except it didn't look as cool and had a cord.

That’s interesting, I always found those vastly superior to all other solutions. They dry my hands the quickest, only the copycats come close.

Not sure I like this article. I would have liked to see the Levoit LV-PUR131 which is rated for 1000sqft/hr, 500sqft in 33 mins at $190, instead of the little one which we know will have a really low CFM/CADR.

Blue Pure 211 rated 540sqft, GermGuardian rated 167sqft, Honeywell HPA160 rated 170sqft, Dyson Hot + Cool Air Purifier rated 290sqft. Levoit LV-H132 rated 68sqft,

Also the Levoit is called out for being $150, as their cheapest, however they are on Amazon or at the local box store for $90.

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.

I’m glad you enjoyed it! When you have time, check out one of his BOLTR (bored of lame tool reviews) videos for more of the same. He’s a piece of work.

Some of the best air filtering systems (and also among the most expensive) are systems like the IQAir [1], which are essentially boxes with a fan at one end and a series of filters arranged in an alternating diagonal pattern: Note: / and \ are each separate filters Filter box ___ | \ | Inflow --> / --> Outflow | \ | | / | ‾‾‾ This maximizes the filtration while reducing the static pressure, since the filtration is di…

Be aware that some of the whole house systems might not have a fresh air intake. This can lead to relatively high CO2 levels inside the building and affect wellbeing and cognitive performance.
