... People would be more likely to know the area of their home/floors vs the total volume...
When's the last time you saw a real estate ad with cubic inches/feet/meters on it?
This makes perfect sense.
Well yeah but it's still funny when thought of in the way the caption says
They assume 8-9ft ceilings.
Wrong. People assume metric ceilings. The area in question is also measured in metric.
Yeah, OP fundamentally misunderstanding. Also see: Specs of every wireless router.
A router would be different though. It would keep the same radius regardless of building geometry as it's signal degrades with physical distance from its antenna.
A dehumidifier works by running air through it and removing moisture then exhausting the now dry air out. The dry air would then intermix back into the room's air, lowering it's total humidity level. It may take a little more time based on the turbidity of the rooms air, but a dehumidifier would have the capacity to dry a .25x20x24m the same as a 3x5x8m room as both contain the same amount of air in their 120m³.
Edit: added units
You see this on a lot of products. This is because a lot of people simply don't understand how cubic meters work, or need to think about it where they know pretty much how much floorspace they have. And in practice it doesn't matter, most people have ceilings somewhere around 2.5 meters and these indicators aren't that precise anyways.
I might be wrong but I assumed it's perfectly obvious to OP and it's the kind of joke where something is funny because you stretch the meaning to read it literally. I chuckled actually, despite it making perfect sense.
Who lives on a plane?
People in the rainy parts of Spain.
The Square, the protagonist in Flatland
Super mario?
Snakes?
So I would be best installing it at my nose height?
For best results buy one per family member per floor. Actually better get two so you can have one at seated height too.
Nah the air isn't constrained to the plane so most of it should pass through eventually and get purified, maybe use some fans to speed it up if needed.
Obviously it works up to minus and plus infinity on one of the axes, possibly the Z-axis, though that's not guaranteed (maybe it's a longitudinal or latitudinal moisture remover?)
Nah, it's the surface area of the extent of the effect. (For greatest volume affected, suspend the device such that its effect can reach, unimpeded, a sphere with that surface area.) Dunno how the physics works; something-something Gauss's law, I imagine.
That's actually a proper non-joky perfectly valid and scientific way to justify listing a covered area in square meters rather than volume.
I doubt that's the actual geometry they used and the surface whose area they list, but none the less it's still well spotted.
Omg, my wife and I were looking at air purifiers a couple months ago and I had this exact meltdown.
