I have noticed that also. Luckily I remember which filters are 8 pole but the website really should specify.
N8VZ may also try contacting Inrad. Scott may answer on weekends? John KK9A Dave WW2R wrote The "previous" web site used to implicitly say which filters were 5 pole and which were 8 pole on the ordering page. The new "improved?" website omits this information.
