As long as the mesh filters are religiously cleaned, then the concept is ok. The execution, as perceived from the image in the link, suggests that the pull out is very thin. This would greatly restrict the flow rate through the mesh filters in that part. I would prefer at least four inches internally for air flow.

Mesh-filter based hoods rarely have any capture volume below the filters, as in this case, so effluent not immediately pulled through the mesh can escape. If the asserted 500 cfm is shared 400 in the rear and 100 in the front, clearly the front will be less effective.

Also, this particular unit is only 24 wide and 18 deep when pulled out, much too small in my opinion for anything larger than a one or maybe two-hob induction unit.

Agreed, you won't get much performance out of a piece like this, there is just too much air restriction.

You should take a look at the Faber Velvet or Zephyr Genova. These models have a similar built-in look but a glass canopy that slides out for added capture. However, all the filtration is just below the motor itself which will greatly improve performance over the Cristal.

Thanks, guys! I will move on. I love the Velvet. Have not seen the ZG but will check it out. I know nothing about range hoods.
