QUICK TIPS
Ventilation / Hoods
Proper kitchen ventilation will remove all the greasy, smoky, steamy, gaseous byproducts that you
don’t want hanging around. Catch the byproducts with an updraft or a
downdraft and send them totally out of your home or through a system that
recirculates filtered air. Which system you choose will depend on the
layout and structure of your kitchen, your local building codes, and your
own style preferences.
You’ll pay more for systems with higher
airflow and lower noise ratings. That’s where knowledge of CFMs and
sones will come in handy. CFMs refer to the amount of cubic feet of air a
vent system can move per minute. The National Kitchen and Bath Association
recommends a 150 CFM minimum for all surface cooking appliances. Sones
measure noise level. Fun facts: A refrigerator equals about 1 sone;
ordinary conversation about 4; and a jet plane landing about 256. The Home
Ventilating Institute recommends that kitchen vent fans should not be
louder than 9 sones.
