Whenever you cook food in your home, there is a lot of steam and smoke released into the air. Where does this all go? Well, if you have a properly functioning kitchen exhaust fan, it should be sucked outside, but unfortunately, this isn’t always the case. When your kitchen fan doesn’t do its work, you can have smoke, grease and moisture that does damage to the interior of your home.
How should a kitchen fan be set up? First of all, there should be ductwork leading to the outside; without it your fan is useless. The ducts should run straight, since too many turns will decrease your fans efficiency. It should have a cover over the vent on the outside to prevent pests from coming in through the ducts, and it should be located at least 10 feet away from any air intakes you have.
If your fan has replaceable filters, you should make sure to replace them regularly. Grease can build up in these filters, and that would be a fire hazard.
