How to Select the Ideal Range Hood for Your Residence

Installing a kitchen smoke extractor in your kitchen is the greatest way to deal with moisture, heat, and cooking grease. You may choose the ideal built-in, range, and island design for your kitchen from various designs and styles.

Hood Ventilation for Ranges

Before shopping, note the shape, size, and mounting style of the kitchen hood vent you intend to replace or install. The new hood should be 3 inches longer on each side and as least as wide as the cooktop or range. 30 and 36 inches wide are the most typical widths. Install a hood 20 to 24 inches from an electric cooktop and 24 to 30 inches from a gas cooktop for best results. Always review the detailed specifications to ensure optimum mounting height.

How you will duct your hood is the most crucial choice you’ll make when purchasing a stove hood vent. For exhaust, there are three possibilities:

Ducted or Vented

To remove irritants, it is advised to duct the hood to the outside. Your range hood’s exhaust ducts will be shorter and more effective if you mount them to an exterior wall. Consider a more powerful unit if your ducted range hood attaches to an inside wall or island because the air needs to be forced farther away. To maximize the range hood’s effectiveness and overall performance, the ducting installation must be done correctly.

Duct-free, Nonvented, or Recirculated

All three of these terms are equivalent. To catch irritants, the air is drawn through a charcoal filter before returning to the kitchen, according to their explanation. For this option to work properly, you must modify your filters at least once every few months. This choice does not call for ducting.


These are hoods that support both ducted and unducted airflow. Duct outdoors for optimum ventilation results.

Range Hood Power

Range hood air circulation is measured in cubic feet per minute (CFM) (CFM). Purchase a range hood with at least 350 CFM if you frequently engage in heavy cooking that produces steam or potent odors. It is advised to ventilate at a minimum of 1 CFM per 100 British thermal units (BTU) while using high-output gas stoves or cooktops. If 45,000 BTU is your high-output burner output, search for a range hood that offers 450 CFM for the best air clearance. However, the hood will be noisier the greater the CFM.

Range Hoods Filters

In ducted hoods, aluminum filters catch grease before smoke and odors are expelled. Depending on usage, wash your dishwasher’s aluminum mesh grease filters once a month. If you use a lot of oil when cooking, wash them more frequently (such as in a fryer or wok). To prevent grease and other tiny molecules from being blown back into the kitchen, non-duct hoods utilize charcoal filters. These charcoal filters must be changed every few months because they can’t be washed (depending on cooking frequency). Filter indication lights are sometimes included with hoods to let you know when it’s time to replace your filters.
