All five of these are ducted or ductless convertible. Ductless needs a charcoal filter, and only two of the five say one is in the box.

Buyer checklist
We read all five listings off the live Amazon.com pages including the detail tables and compared them on the two things that decide whether a ductless installation works: what filtration is actually supplied, and how much air the fan moves. Filtration is the finding. Aluminium mesh filters, which all five have, capture grease; only a charcoal or activated carbon filter removes odour, and only two listings state one is included. Airflow we have reported in CFM where published, noting that the figures are the manufacturers' own and that ductless operation reduces effective extraction because the air is pushed through a dense filter. We also found a dimensional contradiction worth flagging: the Tiesay listing's title says 36 inch while its bullets repeatedly say 30 inch and give an overall width of 35.2 inches, so the size needs confirming before ordering. We have not installed or measured any of these, and no noise or extraction claim below is ours.
Where the air goes. A ducted hood pushes extracted air outside through a duct, taking grease, odour, heat and moisture with it, which is strictly better and requires a route through a wall or roof. A ductless hood passes the air through filters and blows it back into the kitchen, so it removes grease on an aluminium mesh and odour on a charcoal filter, and returns the heat and the water vapour to the room. Every hood here does both depending on installation. If you can duct, duct; ductless exists for flats, interior kitchens and rentals where you cannot.
On three of these five, yes. The COMFEE 200 CFM model includes an aluminium and activated carbon composite filter, and the 30 inch wall-mounted model includes two charcoal filters. The other three, the COMFEE three-speed, the Tiesay and the ZLINE, list only reusable aluminium filters in their bullets, which means ductless installation needs carbon filters bought on top. That matters twice: once for the initial cost, and again because carbon filters are consumable and typically need replacing every few months, where aluminium mesh filters are washed and reused indefinitely.
More than a ductless hood will effectively deliver, which is the honest answer. The published figures here run from 200 CFM on the smaller COMFEE to 400 on the ZLINE's top speed and 450 claimed by the Tiesay. The conventional guidance is to scale extraction to the heat output of the hob, with gas cooking needing substantially more than electric. The ductless caveat applies to all of them: pushing air through a dense carbon filter costs airflow, so a hood rated at 400 CFM ducted moves meaningfully less when recirculating, and no manufacturer publishes the ductless figure.
