Hy NAMVn,
 
What a great option! I have no experiences with the Alevo3D replacement, but I think the brand itself is bona fide. They specialize in air filtration for 3D printers (i'm not affiliated). I actually bought their aftermarket enclosure (this one) to be cut into the side panel of my S5 to have carbon filtration and luckily i have not done that yet, because this option is way better of course.
 
Looking at the filter I have here, which has the same section view (carbon filter combined with hepa 13 filter), I would not worry about the flow resistance of it compare to the original filter. The most restricting part of the filter is the hepa 13 filter, not the very coarse carbon filter part). So airflow would about be the same.
 
Furthermore from what I know from the firmware considering the airmanager; the airflow is only monitored to detect a clogged filter. All hepa 13 filters will have higher flow resistance toward the end of their life span, so small deviations by placing a different filter should not give problems. 
 
Considering it's the same price, I'm just going to order and try is, since my filter is up for replacement (again, not affiliated, but I just care about air quality al lot in the room where I print)
