Not the best devices though. They're inappropriate for a dust collection
device. They're intended to take "clean" air and make it "very clean" -
they don't have the airflow for a dust collector and if you feed them
dirty air they clog in no time at all.

Find a (I don't know the British for it--in the US it would be "garage" or
"service station"--anyway the kind of place you take a broken motor vehicle
to get it fixed) that specializes in large trucks and you should be able to
get a couple or three rather large used truck air filters for free (they
normally get tossed).

If he's using a Bill Pentz cyclone then the filter is going to be getting
air that is pretty clean--the filter on a good cyclone is to catch the tiny
amount of very fine stuff that the cyclone doesn't take out--one of the
advantages of a cyclone is that you can use a much finer filter on it than
you would if the filter was the primary dust removal device. As for
airflow, if you stack enough of them they'll flow as much air as you want.
Bill recommends this approach in fact.

Make them yourself. An internal cage of welding rod, then an "air sock"
pulled over that. There are lots of materials that work as a filter,
cheap polypropylene fleece is easy, a woolen felt gives the best
filtering. When they get dirty, take them off and wash them.
You can make air socks up to 40' long (at least), but if they're that
big, put a few zips in them otherwise you can't find a washing machine
big enough.
