What It Means
Unknown Spa Filter Cartridge / Wrong Cartridge Risk
Likely Causes
- Label washed off cartridge
- Aftermarket cartridge installed
- Wrong length or thread style
- Bypass/standpipe mismatch
- Brand/model unknown to customer
Next Checks
- Capture cartridge length, outside diameter, inside diameter, end-cap style, thread/handle style, and any molded numbers
- Photograph the filter bay, weir/skimmer area, and spa model label
- Do not order by brand name alone; match dimensions and current cross-reference
- If flow improves only with the filter removed, record that as proof but do not leave the spa running unfiltered
- Save the proof packet for the counter or vendor before buying
