... 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.

[–] [email protected] 23 points 5 months ago

Well yeah but it's still funny when thought of in the way the caption says

[–] [email protected] 4 points 5 months ago (1 children)

They assume 8-9ft ceilings.

[–] [email protected] 13 points 5 months ago* (last edited 5 months ago)

Wrong. People assume metric ceilings. The area in question is also measured in metric.

[–] [email protected] 3 points 5 months ago (1 children)

Yeah, OP fundamentally misunderstanding. Also see: Specs of every wireless router.

[–] [email protected] 3 points 5 months ago* (last edited 5 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 .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.

[–] [email protected] 32 points 5 months ago

A 2m ceiling seems rather claustrophobic to me

[–] [email protected] 13 points 5 months ago

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.

How does that work when a standard door is 2.1m tall?

[–] [email protected] 20 points 5 months ago (2 children)

Anyone who has ever done anything related to doors knows, there is no such thing as a standard door.

My wife: We don't need to replace the door frame just the door

Me crosscutting and ripping my new door to fit the old frame: Great idea honey

[–] [email protected] 1 points 5 months ago

That’s usually from the previous home owner who thought they could install the previous door themselves and not knowing the difference between a rough opening and finished opening.

[–] [email protected] -4 points 5 months ago* (last edited 5 months ago)

There is absolutely a minimum size that doors need to be for almost any house. Yes you can incorrectly install other doors, but codes provide a minimum size for professionals to follow when installing. Which is 2.1m in most of the world. Other places will have their own standard size door, but yes every country absolutely has standard door sizes.

Why do you claim otherwise…? Just go look up any big box store door catalog lmfao, plenty of standard door options for even home owners. If you’re cutting a door to size, you’ve done fucked up in almost every case.

And it’s funny you say something like this while being completely off base about story heights… fucking lmfao. Sure we should listen to your “expertise” hahahah, you don’t even know how tall a room is, yet we should trust you know anything about doors? Really? Seriously… dude?

[–] [email protected] 6 points 5 months ago (1 children)

You had a great post going until you screwed it all up by saying ceilings were only 2m high.

Who lives on a plane?

[–] [email protected] 27 points 5 months ago

SNAKES,

MUTHAFUCKA!

[–] [email protected] 8 points 5 months ago

People in the rainy parts of Spain.

Super mario?

The Square, the protagonist in Flatland

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?

[–] [email protected] 3 points 5 months ago (1 children)

For best results buy one per family member per floor. Actually better get two so you can have one at seated height too.

[–] [email protected] 2 points 5 months ago

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.

[–] [email protected] 7 points 5 months ago* (last edited 5 months ago) (1 children)

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?)

[–] [email protected] 3 points 5 months ago (1 children)

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.

[–] [email protected] 3 points 5 months ago* (last edited 5 months ago)

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.

[–] [email protected] 3 points 5 months ago

Omg, my wife and I were looking at air purifiers a couple months ago and I had this exact meltdown.
