How to remove filter from a Craftsman wet dry vac?
To remove the filter on a Craftsman wet/dry vacuum model 12512002, unplug the vac, unlatch and lift off the power head, then loosen the filter retainer (filter nut) and slide the cartridge filter straight off the center mount. Reinstall by pushing the filter fully on and tightening the retainer.
Step-by-step: removing the cartridge filter (dry pickup)
- Unplug the power cord from the outlet.
- Undo the latches and lift the power head off the collection tank.
- Locate the filter retainer on top of the cartridge filter.
- Turn the retainer handle counterclockwise to loosen and remove it.
- Pull the cartridge filter straight off the center mount (do not twist hard).
- Clean or replace the filter as needed, then reinstall.
Reinstall tips (so it seals and suctions correctly)
- Push the cartridge filter in until it stops against the power head.
- Reinstall the retainer and tighten it clockwise until snug.
- Make sure the filter is seated evenly all the way around.
- Never run dry pickup with a torn filter; replace it.
Wet pickup note (important)
After wet vacuuming, remove the foam filter and install the correct dry-use filter before vacuuming dust again. This prevents poor suction and helps protect the motor.
Quick reference table
| Task | What you do | What to watch for |
|---|---|---|
| Remove filter | Loosen retainer, slide filter off | Don’t force; pull straight |
| Install filter | Push filter fully on, tighten retainer | Even seating prevents leaks |
| Switch wet to dry | Remove foam filter, install dry filter | Dry pickup without proper filter clogs fast |
Why it matters
A properly seated filter and retainer keeps airflow sealed at the power head. That improves suction, reduces dust blow-by, and helps prevent debris from reaching the motor.

Quick “what it does” reference
| Part or accessory | What it does | When you replace it |
|---|---|---|
| Filter (cartridge/HEPA) | Traps dust and fine particles | Reduced suction, dust blowing out, visible damage |
| Hose and nozzle tools | Direct airflow to the pickup point | Cracks, poor fit, clogs that will not clear |
| Tank and latches | Holds debris, seals the unit | Leaks, broken latch, poor sealing |
| Wheels/casters | Makes the vac easy to move | Broken wheel, wobble, hard rolling |
Why it matters
Knowing the correct part names helps you match the right replacement to your Craftsman 12512002, especially for wear items like filters, hose attachments, and latches. It also speeds up troubleshooting when you have low suction, dust leakage, or clogs.

Where to find model number on Craftsman Wet Dry Vac?
On the Craftsman wet/dry vacuum model 12512002, the model number is printed on the serial plate (serial label) located on the vacuum. Use that exact model number when ordering parts or checking the correct operator information in the 12512002 operator's manual.
Where to look on the vacuum
Check these common label locations first (the serial plate is typically easy to spot once you know what you are looking for):
- On the tank/canister area, often near the back or lower side
- On the power head (motor cover) area
- Near the handle or cord wrap area
- Close to the inlet port where the hose connects
What the label usually includes
The serial plate typically lists more than just the model number. Look for:
- Model No. (for this unit: 12512002)
- Serial number
- Electrical rating information (volts/amps)
- Safety markings (many wet/dry vacs are marked double insulated)
| Label item | What to use it for |
|---|---|
| Model number | Matching the correct parts list and manual |
| Serial number | Identifying production details for service |
| Electrical ratings | Confirming correct power source and extension cord sizing |
Why it matters
Using the exact model number prevents ordering the wrong hose, nozzle, filter hardware, or attachments. For example, if you are replacing an attachment, matching by model helps ensure fit with items like the shop vacuum crevice tool, 1-1/4-in 551012109 or the shop vacuum utility nozzle 551004113.
