I thought those were considered to be a bad idea because they blasted all of the germs from your hands all over the room? Also, my kids won't use them because they're too loud.
what do you think has more germs, your recently washed hands or the bathroom around you? Also, the dyson's do the same thing.

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.
From the HN guidelines: Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.
I guess I'll bring up the "let your kids play in dirt argument" and see if I get any comments. I've personally taken this path in life and I seem to have much fewer allergies and immune issues than lots of my friends who grew up with hospital-like childhood circumstances. It could just be observor bias but it seems like there is some underpinning to the theory of if you don't use it you lose it when it comes to immun…
On the flip side, if you have young kids, the heaters are great because there's no hot element to burn themselves on like a normal space heater, and no fan to stick their fingers in.
The built in t-stat + timer are nice as well.
I've spent many hours navigating the air purifier market and it is one of the most opaque and customer-unfriendly ones I have ever seen. Beyond the advice given in the article, it's also important to check what the filter exactly is. Some filters are washable, but it often means that they are not as thorough as HEPA filters, which is a big deal if your goal is to avoid the dreaded PM2.5 that are as far as I can tell…

The fan also sucks compared to something like a Vornado. "Buffeting" of air is not a practical issue when using a fan - you want a fan that can create a lot of air flow. The Dyson fan comes across form first then making up reasons to explain the form retroactively. It feels like an interesting look is the goal rather than something that's actually better. Am I wrong about this? Do people that have the fan like it? Is…
We bought a Dyson fan when we had very small children that liked to stick their fingers into moving fan blades. It works really well for that purpose.
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…
Fan intakes on non-purifying Dyson do get plugged with dust over time, so it makes sense to add filters. Aside from whether it makes sense to advertise them as air purifiers.

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.

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 juic…
Or, as some journalists found, just squeeze the bag in your hands and get more juice out of it than the Juicero did. You know you've over-engineered your product when it's that hard to get something that simple right.
"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…
