A microhood combination combines two of the most important units in your kitchen into one handy appliance. This combination is installed over the stove, just as a range hood normally would be, but it also includes the microwave oven. For most people, the microwave and range combination is a great way to have both appliances without giving up valuable space.

The entire microwave range hood weighs between 50 and 100 pounds; the weight will depend on the microwave you choose - the more features, the higher the weight. Most units also include, along with the microwave and hood, a night-light/stove top light and a two-speed fan.

You also have the option of having a microhood combination that vents any cooking smoke from your kitchen. The nice thing about vents is that they remove any exhaust, small particles and cooking odors from your home and send them outside through the ducts. The non-vented variety sends the smoke and odors through a charcoal filter where they're removed from the air before being sent back into the kitchen. Whether you go with the vented or non-vented, you'll need to make sure you keep the filters and vents clean so your microwave won't overheat due to inadequate ventilation.

There are several factors you should keep in mind when trying to decide on which appliance to buy. For example, many units are usually mounted fairly high over the stove, making it difficult for children or smaller adults to reach the microwave. Even worse, it may be unsafe for someone who can't comfortably reach the microwave to try and remove something hot. Another possible problem is the location of the microwave - if you're cooking something on the stove and need to reach into the microwave, you may knock something over or burn yourself on a hot pot.

A microhood combination can sell for as little as $250 and as much as $1100 - the price will depend on what features you want. The smallest microwaves are only 12 inches deep so the vent really only covers the back burners. If you want to ensure good coverage of the full stove top, then look for a microwave that has a greater depth - see if you can find one that will extend over most of the stove. Also make sure that you know where the vents are and how to access them - you want to pick a unit where it's easy to keep the filters clean.
