The average kitchen accumulates 4 gallons of grease per year, so it's incredibly important to have good ventilation.
Proper ventilation clears the air of smoke and odors and prevents particles from accumulating on ledges, curtains and cabinets.

Are Downdrafts Any Good?
The quick answer is that they're better than nothing.
Downdrafts have great CFM (cubic feet moved per minute). Unlike hoods, however, downdrafts have no capture area, so they cannot handle a vast quantity of smoke or heat. For this reason, downdrafts cannot handle professional ranges.
Where Are Downdrafts Best?
Downdraft venting is primarily used in kitchen islands or peninsulas — places where a traditional hood might be difficult to install or where you don’t want to block the view.
Downdrafts typically can rise above a cooktop anywhere from 8-19 inches and can have blower motors which can be internal (placed under the counter), in-line (placed in between the riser and the outdoor vent) or remote (motor is on the outside). These motors can vary from 200 CFM to 1600 CFM depending on the manufacturer.
Most Powerful Downdrafts

How To Downdraft Properly
(Assuming you love to cook)
- Set your expectations accordingly. Downdrafts are not as efficient as regular hoods
- Duct properly. Use bigger duct, so the air flows freely. Always use metal, not plastic duct.
- Do not bend the duct more than once or run it longer than 20-25 feet
- Do not use with a professional range....but you can use an induction, because it does not emit as much heat
- If you are looking for maximum power, then use an outside blower
