I looked into these.

See if you can get the actual manufacturer spec. The sellers are being told they are 870 cfm. In the spec sheets there should be a ...m3/min rating is what I found on most. For example 13m3/min. Ask them if that rating is for the unit set on high.

If you go to www.convert-me.com you can input whatever figure they give you and get the equivalent cfm rating. For example, the 13m3/min converts to 459 cfm actual.

Oh, and take the glowing feedback on the items with a grain of salt. Not that they are pulling anything or the like. I only say that as when I was looking at them and contacted some of the buyers I was quite surprised at how many had left great feedback on how great the item was and come to find out they had not even hooked the item up yet. Of course, that is just my experience on that one.

We ended up not buying one even though the price was certainly nice. Could not find one that we felt comfortable with the cfm rating. Some took specific filters that you supposedly could only order through the eBay seller if needed again. Probably not a common occurance, but we just tried to think of the possibilities.
Wondered if we did need one if the seller would still be on eBay or in business. Also, did not like the fact that the vent was supplied with flex tubing. Everything we read said that this reduced the flow characteristics of the vent sometimes significantly.

There were other reasons we bought elsewhere, but that should get you going so you can find what works best for you.

Hi -
What did you end up buying? I am in the same situation - new house, great apps., but can't see spending thousands on a hood ...
Anyone have direct experience with these no name hoods?
Thanks,
Ame
