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.
How does that work when a standard door is 2.1m tall?
Anyone who has ever done anything related to doors knows, there is no such thing as a standard door.
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?
Most ceilings are a foot and a half or more above the door
You had a great post going until you screwed it all up by saying ceilings were only 2m high.

But it does matter… someone with vaulted ceilings at 12’ instead of 8’ would have this be 50% as efficient, which is huge.
The fact that you blundered the only important piece of information is ironic as shit since it absolutely matters….
Who lives on a plane?
SNAKES,
MUTHAFUCKA!
People in the rainy parts of Spain.
The Square, the protagonist in Flatland
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.
