Faber rangehoods were recently feature in the July 2009 issue of The Retail Observer. Touted "The GREEN Ventilation Company," Faber hoods were praised for keeping energy costs down in the home, eliminating harmful odors (such as gas fumes), and their very low energy consumption.
Some excerpts from the article:

Besides using very little energy, Faber hoods help to keep energy costs
down in the home. Turning the rangehood on keeps cooling costs down. Humidity
and heat build in the kitchen when cooking, so more money is spent on
cooling than hot air. By using a rangehood, the elimination of cooking
by-products (heat and humidity) help keep air conditioning costs down
By using effective ventilation in the home like a Faber rangehood, harmful
odors (like gas fumes) are eliminated from the home. Also humid, greasy, steamy
air over time can cause mold and mildew to build up in the kitchen, causing
possibly respiratory problems. Faber even has hoods that can be used as all day
air purifiers. The Matrix, Orizzonte and Velvet have a 24-hour anto-pollution
mode, which runs the hood at approximately 60 cfm all day. The whole home can be
ventilated all day long and refresh the air. So for as little as $1.14 per hear,
there is a reduction of overall air cooling costs, and a health, safe and green
home for the consumer.
Faber rangehoods have a very low energy consumption- less than $10 per year
spent on electricity.
Faber has always been forward thinking for over 50 years. Faber is
constantly working on new technologies to improve energy efficiency and make
products greener. Faber is introducing hoods that use energy efficient LED
lighting and also require less energy to operate overall because of more
efficient ventilation technologies.
