HW-302 isn't a hang on filter, that is just the model number for the sunsun 3 stage canister with out the uv sterilizer. The bands of this filter seem to vary, but the part number usually stays the same.
After a week of use the new impeller has quieted down a bit on mine.
A bit off topic, but i just bought a used tank yesterday and it came with the fluval FX5.. that thing is MASSIVE, from the pictures i was expecting something about the size of a cfs 500, not even close. That thing is larger than most modern pool filters, lol
