Kitchen Ductless Cooker Hood
Ductless kitchen cooker hoods suck in all of the cooking odors in your kitchen, along with minute particles of grease and dust that dirty up your kitchen and air. Versions that are ductless are usually the second choice in cooker hoods. When it is possible to install a hood that can be vented to the outside, that will be the more popular choice, since they expel stale kitchen air directly outside. The cooker hood must be vented outside; it cannot be vented into an attic or an interior wall. Ductless cooker hoods work differently than vented cooker hoods: they do not pull kitchen air outside, but rather filter the air and then release it back into the home. A ductless cooker hood will not work without a clean air filter. Many use charcoal filters, which make an excellent choice for cleaning the air in a kitchen, because they absorb odor and other residue that can make the kitchen smell unpleasant. If the hood has an exterior aluminum filter, the homeowner will not have to replace the filter, but it will need to be cleaned.
Ductless cooker hoods are not as effective at cleaning the air in the kitchen as vented cooker hoods, but for many people, they are the only reasonable option. If the layout of the kitchen prohibits the addition of a vented cooker hood, then a ductless one can be a good choice. As long as the filters are cleaned or replaced on a regular basis, this version is a very effective way to keep a kitchen smelling fresh.
