Installing a ventilation hood above your cooking surface helps provide a cleaner, healthier cooking environment. No matter if it's a dedicated hood or a microwave combination hood. Properly removing the smoke and grease from your cooking surface is highly recommended.
Exterior direct vented hood's provide excellent venting and evacuation of harmful smoke and vapor. These hoods required duct work to run from your cooking surface to an exterior wall. And provide far superior ventilation of the room compared to a recirculating hood.
