Which filter does my Jacuzzi hot tub take? Lookup by collection, model and year
It depends on the collection and, for several models, the year. In the two published tables we compared, most J-200 and J-100 models take the 373045 (4-15/16" × 13-5/16"), while the J-230 from 2008, J-270 and J-280 take the 2540-381 (8" × 15-1/2"). J-300 spas take two 6000-383A ProClear 60 sq ft cartridges. Current J-400, J-500 and J-LX spas use a three-filter set: a 6473-157 pleated upper, a 6473-161 micron lower and a 6000-383A for the jet pump. Older J-400s (2006–2012) used different parts, and the 2023+ J-200 ProClassic uses an oval 6541-853.

A Jacuzzi parts retailer lists Pleatco PJW60TL-F2S, Unicel 6CH-960 and Filbur FC-2800 as replacements; the catalogs list those against Jacuzzi 6540-476. | 60 sq ft; 15.45" tall × 6.697", 2.375" opening (retailer spec) | 6CH-960 |

Sizes and equivalents come from the Unicel 2026 Replacement Guide, the Pleatco 2023 catalog and the Filbur catalog, matched on the factory number. Where no catalog lists the factory number, the table says so rather than guessing a look-alike. A trailing “J” (for example 373045J) is how Jacuzzi suffixes the same part number in both dealer tables.

Rows combine two dealer tables: Spa World’s Jacuzzi filter guide (Australia) and the March 2024 Jacuzzi Direct filter table published by a French Jacuzzi dealer. Where they give different years, both are shown. Skimmer and filter bags (6570-392, 6570-398, 2540-389) and the J-LX weir (6540-188) are listed in those tables too but are not cartridges, so they are left out here.

Where the two tables differ
- J-235 before 2012: only the French table covers it, and it lists the 35 sq ft 6000-136. Spa World starts the J-235 at 2012 with the 373045.
- J-270 and J-280 start year: 2005 in the French table, 2007 in Spa World’s.
- J-LX / J-LXL end year for the two-ProClear setup: 2021 (Spa World) vs 2022 (France). Both move to the 157/161/383 set for 2023.
- J-465 cut-over: France says before May 2007 for 2000-498 and May 2007–2011 for 2540-383; Spa World words it as “up to April 2007” and “up to May 2011”. A 2007 J-465 needs a look at the old cartridge.
- J-400 end year: Spa World lists 2013–2023 for the named J-400 models; the French table says 2013 onward with no end.
Both tables come from dealers outside the US (Australia and France), and we found no public fitment table from Jacuzzi itself, so treat the years as a strong guide rather than a guarantee.
How to confirm yours
- Read the part number printed on the old cartridge. Expect a J suffix on some (373045J, 6473-157J).
- Jacuzzi’s owners center says filters are sold through local dealers, and that the spa serial number is in the equipment bay on top of the load box, typically 9 digits starting with 100. Give a dealer the serial if the year is near a change-over.
- If the label is gone, measure diameter and length (our filter-size guide shows how) and compare with the sizes above. A J-400 or J-500 with a short upper cartridge and a small closed-end lower one is the 157/161 set.
Why one cartridge size can carry two different square-foot ratings: our explainer with Unicel’s pleat-count table.
