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 meters and these indicators aren’t that precise anyways.
This product will eliminate odours in your home, but only in one plane

A 2m ceiling seems rather claustrophobic to me
SchmidtGenetics@lemmy.world 11 months ago
How does that work when a standard door is 2.1m tall?
Thorry84@feddit.nl 11 months ago
Anyone who has ever done anything related to doors knows, there is no such thing as a standard door.
gregorum@lemm.ee 11 months ago
Most ceilings are a foot and a half or more above the door

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.
ColeSloth@discuss.tchncs.de 11 months ago
You had a great post going until you screwed it all up by saying ceilings were only 2m high.

Snakes?

Let’s just say every device advertising it could work on X meters (square, cubic, whatever) is a lie.
What are the conditions? How pronounced you expect your result to be?
This is especially funny with heaters, for example, when heaters of the same power advertise vastly different area of effect and people go “Oh! This 1500W heater can heat up 50 square meters, so much better than this 2000W heater advertised for 30 square meters!”

So I would be best installing it at my nose height?
BluesF@lemmy.world 11 months ago
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.
Aceticon@lemmy.world 11 months ago
Obviously it works up to minus and plus infinity on one of the axes, possibly the Z-axis.
milicent_bystandr@lemm.ee 11 months ago
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.
Aceticon@lemmy.world 11 months ago
That’s actually a proper non-joky perfectly valid and scientific way to justify the covered area in square meters.
I doubt that’s the actual geometry they used for their surface, but none the less it’s still well spotted.
Adalast@lemmy.world 11 months ago
Omg, my wife and I were looking at air purifiers a couple months ago and I had this exact meltdown.
Darkassassin07@lemmy.ca 11 months ago
… 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 add with cubic inches/feet/metets on it?
This makes perfect sense.

Well yeah but it’s still funny when thought of in the way the caption says
Guy_Fieris_Hair@lemmy.world 11 months ago
They assume 8-9ft ceilings.
woodgen@lemm.ee 11 months ago
Wrong. People assume metric celeings. The area in question is also measured in metric.
ma11ie@lemmy.one 11 months ago
Yeah, OP fundamentally misunderstanding. Also see: Specs of every wireless router.
EtherWhack@lemmy.world 11 months ago
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 .25x20x24 the same as a 3x5x8m room as both contain the same amount of air in their 120m³.
