The charcoal filter is not only an effective filter, but an efficient deodorizer as well. It gets rid of unpleasant odors that cooked foods release into the air. Because the charcoal filters can only hold so much grease and other chemicals, they need to be replaced every time they noticeably lose their efficiency. These filters are helpful in creating a nice odor-free home or business as long as they are replaced regularly.

The grease filter has been designed to trap the greasy oil vapor that deep fryers release during cooking. When oil reaches a certain temperature, it escapes in the form of vapor and these quality filters attract the oil in the vapor to stick to them, therefore allowing only clean air to pass through.
