The reason for saving money on the repair is simple: Non-ducted hoods have
little or no value, except for directing steam away from the cabinets, which
may suffer over the years from the moisture.

The non-ducted hoods do more than just redirect steam, the metal mesh
"filter" is intended to collect vaporized grease which will otherwise
end up adhered to your cabinets.
