Am I dumb or should i return my degree ?

[funn3r]

Hi,

 

i was looking for air purifiers and i found my favorite one. It's Xiaomi Mi Air Purifier Pro.

But i am little bit confused with purifying performance which is 5000m3/h. 

If I am counting right, it's 5000000 Liters per hour, which is about 1400 Liters per second.

 

Seems little strange to me  ? What am I missing here ?

CADR of up to 406m³/h, 48m² effective coverage

About 100 liters per second, still not sure if it's real number or they're measuring spherical horses through vacuum but it looks more believable than 1.5 m3 per second.

406m³/h

406 m3/h is still 112 Liters per second, at my local vendor is specified 5000m3/h i got

confirmed that value by theirs employee.

Keep your degree. More likely your math is good but the numbers manufacturers provide are incorrect

They lie, mostly cus they don't know and just repeat what they have been told.

Ask him how they've put a jet engine in there then.

Okay so how can i get real performance then ?

Has anybody some experience with it ?

As with most things, by reading reviews.

Tell them they have a clear FAILURE TO COMMUNICATE there. As even their OWN SITE says something completely different.

So yeah personally i would say #$%^& 'm and go with a company that does not lie to its customers. (if by accident or not this is really really bad, they showing you perfectly how much they care about you).

See, it looks like the CADR rating listed on their site is not how much air it puts through itself but some obscure method of evaluating of much particulate matter it can clear, it depends on the pollutant. And 5k cubic meters per hour might be it's peak air pulling capability but since it seems to be rated only for 31W, that number are either reached only for some very short periods maybe in smth like turbo mode or that's a complete bullshit.

Well i think you got the right answer right there.
even 500m³/h is a complete LIE, that physically impossible to do in such small container. Hell its even more then the size of room it was designed for. It makes no fucking sense at all. I so hope everyone sees that shit and don't fall for their lies.

Cus as long as people keep giving them money they will keep lying to their customers, cus we are giving them money for it....

I doubt that these numbers are any different from other manufacturers, it's just an usual bullshittery with measuring stuff, like TDP with CPUs, PMPO wattage with sound systems etc.

I suspect the numbers are simply a blatant lie and they get away with it because it's not something most people can easily measure, and so they don't get called out.  I've seen suspicious things when it comes to air-related products before.  Specifically, some Dyson fans' claimed flowrate is way above that of some other powerful traditional fans' claimed flowrates, and while I don't have hard data, I strongly suspect that this is not accurate, particularly given how little airflow you feel from them vs something more traditional.

[Man]

@funn3r No idea!

 

Nice clickbait, though! I totally fell for it, even though I'm a self-proclaimed expert when it comes to clickbaits and try my best to avoid them. 

 

Couldn't resist clicking this one though, which is something!

 

Consider it a compliment, mate.
