Choosing the Right Kitchen Ventilation Systems is More Important Than You Think
There are three basic factors to be considered when choosing a kitchen ventilation system – price, noise, and effectiveness/capacity. System effectiveness is often measured in the amount of air the system can remove per minute (CFM or cubic feet per minute). Obviously, system with larger CFM measures is often more effective in removing air and grease. For typical-sized kitchen in a four-bedroom house, the recommended minimum kitchen ventilation system capacity is 150 CFM.
Keep in mind, however, that there is often a trade-off between the noise level and system capacity. And, ventilation system capacity usually doesn’t tell the whole story about system effectiveness. Ventilation system effectiveness also depends on the draft type. Specifically, there are two major types of ventilation systems: Updraft Hoods and Downdraft Vents.
