Jandy Pool Filter Guide: CS, CL, DEV Models and Parts
The short answer
Complete Jandy pool filter guide: CS and CL cartridge models, DEV DE filters, replacement cartridges, part numbers, pressure gauges, and price ranges explained.
In This Guide
Jandy equipment shows up on a lot of pool pads, usually alongside a Jandy pump, a Jandy heater, and a Jandy automation panel, because builders tend to install the whole system from one brand. That is convenient until you need a replacement cartridge or a new gauge and discover the model naming looks like a license plate. CS200, CL460, DEV60: none of it says cartridge or DE on the outside of the tank.
This guide decodes the Jandy filter lineup, explains which model suits which pool, lists the replacement elements and the aftermarket equivalents that fit them, and covers the small parts that fail first. It is a brand reference, not a cleaning tutorial. If you came here to clean or backwash your unit, jump straight to the linked procedure guides in the maintenance section below.
Which Jandy Pool Filter Is Right for Your Pool?
For most residential pools, the CS series cartridge filters are the mainstream choice: four sizes from 100 to 250 square feet, a single cartridge inside, no valve to buy, and no backwashing. The CL series is the larger cartridge line, running 340 to 580 square feet for bigger pools, longer runs between cleanings, or heavy bather loads. The DEV series DE filters give the finest filtration Jandy offers, filtering down to a few microns, at the cost of a valve, a backwash line, and DE powder recharges after every backwash. Jandy sits under the Zodiac umbrella inside the Fluidra group, so parts availability is good and both OEM and aftermarket elements are easy to source. If you are choosing fresh, size the filter at or above your pool’s turnover requirement rather than matching what was there before.
The Jandy Filter Lineup
Jandy splits its residential filters into three families plus a sand line. The model prefix is the fastest way to identify what you have.
| Model | Type | Filter Area | Suits Which Pool |
|---|---|---|---|
| CS100 | Cartridge | 100 sq ft | Small pools and spas up to roughly 10,000 gallons |
| CS150 | Cartridge | 150 sq ft | Small to mid-size pools, 10,000 to 18,000 gallons |
| CS200 | Cartridge | 200 sq ft | Mid-size residential pools, 18,000 to 25,000 gallons |
| CS250 | Cartridge | 250 sq ft | Larger residential pools, 25,000 to 30,000 gallons |
| CL340 | Cartridge | 340 sq ft | Large pools or any pool wanting long service intervals |
| CL460 | Cartridge | 460 sq ft | Large pools with spas or heavy bather loads |
| CL580 | Cartridge | 580 sq ft | Very large residential and light commercial pools |
| DEV48 | DE | 48 sq ft | Mid-size pools wanting the finest filtration |
| DEV60 | DE | 60 sq ft | Larger pools wanting the finest filtration |
A note on valves. The CS and CL cartridge tanks ship with no valve at all, because there is nothing to backwash. The DEV DE filters and the JS sand filters are ordered with either a multiport valve or a push-pull slide valve, and the choice matters. A multiport gives you the full set of positions including WASTE and RECIRCULATE, which is useful for vacuuming to waste and for lowering water level. A slide valve is simpler, cheaper, and less prone to the torn spider gasket problem, but it only does filter and backwash. If your DEV came with a slide valve and you keep wishing for a waste setting, that is the reason.
Oversizing a cartridge filter is generally rewarded. A larger tank runs at lower pressure, stretches the interval between cleanings, and puts less strain on the pump. If you are unsure what size your pool needs, our sizing guide on what size pool filter you need walks through the turnover math.
Jandy CS200 and the CS Series
The Jandy CS200 is the single most searched model in the lineup, and it is simply the 200 square foot member of the CS cartridge family. Same tank design as the CS100, CS150, and CS250, just a taller tank body and a taller element inside. It suits mid-size residential pools in the 18,000 to 25,000 gallon range, and on a typical suburban pool it holds its clean pressure for four to eight weeks in season before needing a rinse.
Physically, the CS tanks are two-piece: an upper and lower half joined by a clamp band, with a pressure gauge and air relief valve on the lid. There is one cartridge inside, not four, which makes servicing quick. Pop the clamp, lift the top, lift the element straight up, rinse it, drop it back in. No manifold to fight with and no four-cartridge rack to keep track of.
The CS200 takes a single 200 square foot pleated element. Jandy sells it under its own part number and Pleatco and Unicel both publish a direct equivalent, so you have three price points to choose from for the same fit. Confirm the number stamped on your old element or printed on the tank label before ordering, because a CS150 element physically drops into a CS200 tank and simply gives you 50 square feet less filtration than you paid for.

Jandy Cartridges and Part Numbers
Every Jandy cartridge filter takes one element matched to its model. The CS elements use part numbers in the R0554600 style, and the CL elements use their own series in the R0357000 range. Those numbers are a guide, not gospel: Jandy has revised and superseded element numbers more than once across the life of these tanks, and the number on a filter sold in 2012 may not be the number listed for the same model today. Always confirm the part number printed on your existing cartridge end cap or on the tank label before ordering, and if the label has faded, measure the element height and outer diameter and match those instead.
Aftermarket equivalents are widely available and usually cost less than OEM. Pleatco lists Jandy-compatible elements under part numbers beginning with PJAN, and Unicel lists them in its C series cross-reference. Both manufacturers publish cross-reference charts that map a Jandy model to their equivalent, and both are reputable enough that the trade uses them routinely. The practical difference is that OEM elements tend to hold their end-cap bonding a little longer, while aftermarket elements save money if you are on a two-season replacement cycle anyway.
For DEV DE filters, the consumable is not a cartridge but DE powder plus a set of grids. The grids last many seasons if the fabric stays intact; the powder gets replaced after every backwash at the dose printed on the tank label.
Whichever route you take, replace the element rather than nursing a dying one. Our guide on when to replace a pool filter cartridge covers the specific signs that a cartridge is finished rather than just dirty.
Jandy Parts That Wear Out
Pressure gauge. The most common Jandy filter part to fail, and the cheapest to fix. Gauges seize, fog over, or drop to zero after a few seasons of sun and chemical vapor. Any 1/4 inch NPT pool gauge fits, so you are not locked into a Jandy-branded part. If yours is reading wrong, our guide on a pool filter pressure gauge not working covers testing it before you replace it.

Tank o-ring. The large o-ring that seals the upper and lower tank halves flattens and dries out, and then the tank weeps at the seam. Lubricate it with Teflon-based pool lubricant at every cleaning and replace it every 2 to 3 seasons; if you cannot tell where the drip is coming from, work through our guide on why a pool filter is leaking.
Clamp band. The band that holds the two tank halves together corrodes at the bolt and can stretch or crack, which shows up as a persistent seam leak that a new o-ring does not cure. Replace the band as an assembly with its bolt and nut rather than reusing hardware.
Cartridge elements. Covered above, but worth repeating that a blown element is a parts problem, not a cleaning problem, and no amount of soaking brings back split pleats.
Valve seals. On DEV and JS models, the multiport spider gasket or the slide valve o-rings wear and start bypassing water to waste while the valve sits in FILTER. Both are serviceable parts sold separately from the valve body. For a broader look at what is replaceable on any filter, see our roundup of pool filter parts.
Maintaining a Jandy Filter
Backwashing. Only the DEV DE and JS sand models backwash, and the procedure depends on whether you have a multiport or a slide valve. The full step by step, including how long to run each position and when to recharge DE, is in our guide on how to backwash a Jandy pool filter. Do not attempt to reverse flow through a CS or CL cartridge tank.
Cartridge cleaning. For CS and CL models, cleaning means opening the clamp band, lifting the element, and rinsing between every pleat with a garden hose, plus a chemical soak once or twice a season to strip out oils and scale. The complete routine, including the pressure trigger for when to do it, is in our guide on how to clean a cartridge pool filter.
Baseline logging. Whichever model you have, write your clean startup pressure on the tank with a paint pen after every element change. Every maintenance decision on a Jandy filter keys off that number.
Jandy Filter Prices
Expect roughly 400 to 800 dollars for a CS series cartridge filter depending on size, with the CS100 at the bottom and the CS250 at the top. The CL series runs about 600 to 1,100 dollars across the CL340 to CL580 range. DEV DE filters land around 700 to 1,200 dollars, and remember that a DE unit also needs a valve and a backwash line, which adds to the installed cost.
Replacement elements are the real ongoing expense: budget somewhere in the low hundreds per cartridge for CS models and more for the larger CL elements, on a 2 to 5 season cycle. Small parts are trivial by comparison, with gauges and o-rings in the tens of dollars. For a fuller breakdown including installation and long-term running costs across filter types, see our guide on pool filter cost.
If you are weighing a Jandy cartridge unit against a DE upgrade, run the numbers on consumables as well as the tank. A cartridge filter costs less up front and needs no powder, while a DE filter delivers clearer water and a backwash convenience that a cartridge tank can never match.
