Range Hood

A range hood is an “exhaust” hood that is installed over a range. A range hood can be vented to the outdoors to help remove pollutants and chemicals from the air while cooking and cleaning. Range hoods help to filter pollutants and chemicals from the air such as smoke, carbon monoxide, grease, steam, mold and mildew, pet dander, and fumes. The average range hood consists of an exhaust fan, a hood, a filter, and a light. Depending on the type, a range hood may also include ductwork.

Types of Range Hoods

There are two basic types of range hoods—venting and non-venting. Non-venting range hoods are also called “re-circulating.” A venting range hood is probably the best kind to use as it vents to the outside via an exhaust duct or ductwork. A non-ventilating range hood helps to circulate the air, but it basically blows or “re-circulates” air back into the room. Non-ventilating range hoods are less complicated to install than venting range hoods mainly because all you need is an electrical connection. Ductwork, or an exhaust duct, is a bit more complicated and costly to install, but the benefit is healthy, fresh air after each use.

To Vent or Not to Vent

Venting range hoods help to clean the air by venting fumes and pollutants into the air outside. While non-venting range hoods do not vent air to the outside, they are equipped with a filter that helps to collect airborne grease and oil. This collection process helps to prevent the build-up of grease on walls, cabinets, and the ceiling. In addition, non-venting range hoods may also come equipped with a charcoal filter, which helps to absorb odors. It is recommended, however, that homeowners install vented range hoods for optimum performance and maximum benefit.

Range Hood Maintenance

Whether you decide to purchase a venting or non-venting range hood, all range hoods should be cleaned regularly and filters should also be cleaned or replaced on a regular basis. The cost for replacement filters varies depending on the type of filter (i.e., metal mesh or carbon).

Installation Costs

Because venting range hoods require ductwork, they are much more expensive to install than non-venting hoods. In addition, extra features such as automatic shut-off, hi, low and medium settings or attractive lighting can all add to the cost of installing your range hood. Non-venting hoods are fairly inexpensive as they only require an electrical connection. Professionals in the industry and physicians alike agree that the benefits of installing a venting range hood far outweigh the costs in the long run.
