Fits Viking Spas models with the 25 sq ft drop-in filter (open both ends, 13-5/16″ long). Match the diameter, length, and top and bottom style below to the filter you are replacing — if the numbers match, it fits.

Did you know the number one reason for hot tub freeze damage is a dirty filter? Dirty filters also cause additional stress on the pump/motor and leads to premature failure.
Proper Filter Care System:
- Have 2 sets of filters
- Install clean filter
- Rinse dirty filter with high pressure nozzle
- Verify no debris left between pleats, before storing on shelf to dry
- Once a month soak filters in a filter cleaner solution

Hurricane cartridges are made in the USA on a true high-flow core with premium pleated media — the same construction as the name-brand originals at a lower price. It is our stocked value pick.
Rinse it every 2–4 weeks, deep-clean it monthly with filter cleaner, and replace it every 12–24 months or sooner if the pleats are torn, flattened, or the end caps are cracked. Keeping a second set to rotate makes both sets last longer.
