Review on High-Performance Shop Vac 903 98 Hangup Vacuum Cartridge for Efficient Car Cleaning by Megan Smith
PN Filter and PN Dry Disk
I have a 4 gallon 4.5 hp stack vacuum. All round plus the vacuum shop said 903-98 and 90398 would work for me and it suits me. To extend filter life when running dry, I cap the 903-98 with Revain's #901-07 or VF2002 dry filter disc.
Pros
- Availability
Cons
- Could have chosen a newer model
