... 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.

They assume 8-9ft ceilings.

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

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

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.

A 2m ceiling seems rather claustrophobic to me

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

[–] [email protected] 0 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

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.

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?

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

Who lives on a plane?

SNAKES,

MUTHAFUCKA!

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] 0 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] 1 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.
