I'm looking for a small deep fryer and would like something that won't smell up the house. I notice some now come with carbon filters that are supposed to reduce odors. These are usually a sheet of paper impregnated with carbon (probably activate charcoal) or two layers with some carbon granules in between.
From what I know of filtration, a carbon filter in an application like deep fat frying such a filter would have an effective life measured in minutes so I suspect they are just a scam.
Has anyone tried any of the fryers with filters, and do they seem to work? If so, any idea how long?
