All the above forgot toes
Those are not fingers (at least not in English).
Is there a word in English which exclusively means hand-digits or fingers+thumbs or digits-toes?

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 agree on the noise of the Dyson. The quietest Dyson fans are not that quiet. I work in studios that require quiet fans. A Dyson fan that rotates is especially noisy due to the squeaking motor. If you need a quiet portable fan/filter find one that is static and has more than 7-8 speeds, preferably in double figures - and put it close to where you want the air, on low.
The best part from an engineer at Dyson (his last name is Hill): "Dyson has developed its own testing methodology, the POLAR test method, which, unlike the CADR, Hill said, "measures the intelligence of the purifier, the ability for it to know when that room is clean or dirty and automatically react, and its ability to mix that pure air around the room." While Hill agrees that CADR is an important part of purificatio…
Also from Dysons site: "The POLAR test chamber is much bigger than a CADR chambler, and more representative of real-world environments than existing standards dictate with a 81m3 footprint and no external fan to support air circulation – the purifier itself must do this."[1] ie: dyson has written POLAR to exclude external fans into their new "standard". Honestly they also don't clarify what they mean by external fans…

> Any kind of smoke hangs around in a room for many hours well past when you can smell it. But once the sensors indicate that the PM2.5 is gone, everything is fine, right?
If that's sarcasm, you aren't providing enough context for me to pick up what you are putting down. If not, then the honest answer is "I don't know for sure, I'm still researching it." From what I can tell, PM2.5 isn't the end-all be-all metric and sensors can give false readings. That's why I'm building multiple devices with different types of sensors and monitoring multiple metrics. PM10 and PM1.0 are also concerns…
Have you looked at open source smart vivarium projects? Several seem to have good front-end.
This may seem weird, but the reason I first started to explore air quality and sensors was to build a smart vivarium for a reptile.
I didn't go through with that project but it was a waking call for me. Animals need so much environment control to thrive and humans are animals.
So instead I focused on adding sensors and filters to my own home. Nothing fancy so far, just a mix of product that work with google home and smart sockets.

This chain has got me wondering how we count in base 10, but we don't have 10 fingers instead 8 fingers and 2 thumbs. Maybe we have 10 digits, but digits can be fingers or toes so we really have 20 digits. Is there a word in English which exclusively means hand-digits or fingers+thumbs or digits-toes?

Plenty of people need to rethink their parenting then. I laugh when my kid falls down. I scream when I saw my kid trying to stick a key into an electrical outlet, and I screamed when I saw my kid trying to put a finger into a vornado fan. Modern fans aren't the same as the box fans we grew up with. And adult would likely walk away with an emergency room bill and a bunch of stiches. A small child would likely lose a f…
I didn't put a key in an electrical outlet, but in Paris when I was a kid I was having trouble sticking the plug in the 220V outlet so I held it tight by the prongs & plugged it in & boy did that feel weird. I never did that again. I never told my parents about it because I would have gotten yelled at. At camp we put crickets on the electric fence, but nothing happened to them, so I grabbed the electric fence, and th…
I bought an expensive Dyson air purifier for a couple of reasons. It has a remote so I can turn it on from bed. It looks attractive. The sound profile is much different than a box fan for sleeping at night. It can analyze the temperature, humidity, and air quality in real time and turn on if it notices air quality is getting bad. It also oscillates. That said yes it was expensive, but it replaced needing a fan for co…
Compare to your furnace (on fan mode) + air filter ... > It has a remote Check > It looks attractive Check. It's invisible. > sound profile Check. Furnace fans are in the garage. > analyze the temperature, humidity, and air quality Nope. But purpleair will sell it to your for $175. > oscillates Check. Covers entire flat.
Having said that, oscillating fans annoy me because the degree of rotation is almost never controllable. I have very rarely seen fans with a clip underneath that causes the rotation to reverse direction.

Only the worst teachers teach by maiming.
As a side effect, it's probably also more efficient.

I watched my dad putting on a rubber glove to pull out a single prong from a broken plug stuck in an electrical outlet. I was perhaps 2-2.5 years old. I asked why he needed the glove. My Dad with his wry Irish humor said it was to get a strong grip. I told him that I thought I could do it without the glove. He told me to give it a try and I did. What I did was promptly fall on my ass and that's how I learned the powe…
