The weller has a remote switch which is nice, although slightly lower claimed flow rate. Noise levels hard to tell as they don't give full spec, just "<50dB". Hakko filters seem to be cheaper.

I was wrong about the Hakko as you can see a tiny bit of carbon foam on the bottom of this one: https://www.tequipment.net/Hakko/A1586/Fume-Extraction/
Again, this is like $2 worth of material (breakdown), it won't be magic.

the kg no really matter the matter is media filtration material it can have just 1,5kg of this media and can be 100 times more effective than 50kg of activated carbon against most irritant fumes generated while soldering - read my other posts

Not sure what your point is. I was comparing two units with activated carbon, the one with more carbon weight will inevitably last longer.
You can't buy cheap commercial activated alumina systems that I am aware of. Yes it might be worth DIYing your own.

But your claim of 100 times more effective needs a citation. It can be better at some chemicals and worse at others. For formaldehyde its not really significant.

in yours photo diagram you have included comparise activated carbon vs activated alumina (white balls) not impregnated with potassium permagnate ! - white alumina balls have less capacity than alumina impregnated with potassium permagnate - the impregnation of kmn04 on alumina bed doubling its capacity do you understand this ? this is violet alumina called purple pellet (puratex) violet balls and its capacity is declared in % it can have 4 - 8 - 12% of kmn04 and if more have then more capacity you get

white alumina balls apply only in water filtration from heavy metals because its capacity is enough for this operation , the violet (purple) alumina is used for filtering smaller gas particles in soldering fume extractors in high-quality air purifiers like IQAir GC MultiGas

in 3d printer filters they use activated alumina with just 4% of potassium permagnated (kmn04) - consider "just" becoz 4% of impregnated bed have enough capacity to filter 3d print fumes and fit in small filter box - you can allways use 200kg of activated carbon for soldering fumes but you must refill yours filter after 2 months of soldering and 200kg of carbon will cost fortune , but bofa v250 with its indsutrial grade carbon (impregnated by potassium permagnate) will last 6 - 12 months and will cost you more cheaper :)

example of 1kg activated carbon can absorb 100 grams of ammonia and cost 5 euro so if you wanna to filter ammonia the activated carbon choice will be right for you

example of 1kg activated carbon can absorb 0,00001 grams of formaldehyde and it cost 5 euro - its price is unprofitable for removing formaldehydes the profitable price is only in specialised activated carbon industrial grade or activated alumina (speciall versions) who can absorb 10 grams of formaldehyde and it cost 10 euro per/ 1kg i hope you understand this complicated requirements otherwises you will pay and waiste alot of money for building uselles diy soldering filters :)

this are example informations from weller zero smog gas filters:

Wide band gas filter
For cleaning harmful fumes and vapours. The Weller
wide band gas filter consists of 50 % active carbon
and 50 % Puratex. Harmful gases with a high molecular weight are cleaned by the active carbon. Puratex
is suitable for absorbing gases of lower molecular
weight. Because of its composition, Puratex is able
to convert a large number of chemical pollutants by
means of molecular modification into non-polluting
gases.

and this is exactly what i mean
