We have a few sets of the of the old Hakko 493 Smoke Absorber in the office, and they do an adequate job. These new FA-400-04 units replace the 493, and somebody (Hakko) put some thought into the engineering these new ones!

Where the old 493 was a simple fan & activated charcoal filter on a swivel mount, the new FA-400-04 works in a set horizontal or vertical orientation. When sitting face-down, a unique slot is exposed to move 2.6 times more air through the soldering zone, pulling the smoke away from you. The older design needed to be practically over your work-zone to function as well!

It’s designed to use existing 493 filters and accessories and filters up to 80% of the odors from the air. And it’s quieter than the 493 too!
