10 Best T-15 Salt Cell Replacements (October 2026)

A worn salt cell shows up as low free chlorine, a "check cell" light or a controller that keeps asking for more salt. The expensive mistake is ordering the wrong cell: a unit rated for 25,000 gallons on a 40,000-gallon pool never keeps up, and a cell that expects newer controller firmware can leave an older AquaRite or ProLogic board defaulting to the wrong cell type. The Best T-15 Salt Cell Replacements depend on three things: the gallon rating, the firmware and controller you run, and how much cable and cleaning gear you want in the box.

The short answer: the Hayward TurboCell T-Cell-9 suits owners of smaller pools up to 25,000 gallons who want the original-brand part, the XHHEZQ T-Cell-15 Titanium Core suits 40,000-gallon pools with firmware 1.50 or newer, and the Orvex T-15 Upgrade Cell suits owners who want a protective outer layer and a fine internal filter. The rest of the list covers cleaning-stand bundles, full kits with long cables and a bare-bones option with almost no published specs.

TL;DR: top picks at a glance

• Best overall: the Hayward TurboCell T-Cell-9, a genuine Hayward cell that is NSF certified, weighs 3.86 lb and ships with a 15 ft cable, but it is rated for pools up to 25,000 gallons only.
• Best for 40,000-gallon pools: XHHEZQ T-Cell-15 Titanium Core, a 40,000-gallon cell with a 3-year replacement warranty and titanium sheet construction.
• Best for weather protection: Orvex T-15 Upgrade Cell, with an enhanced outer layer against cracking and an upgraded internal filter chip.
• Best for cleaning: KOONDHEEND T-15 Cleaning Stand Kit, bundled with a cleaning stand, long-handle brush and spare O-rings.

1. Hayward TurboCell T-Cell-9: Best Genuine Salt Cell for Pools Up to 25,000 Gallons

• Pool Size: Up to 25,000 gallons
• Part Number: W3T-CELL-9
• Cable: 15 ft
• Weight: 3.86 lb
• Certification: NSF certified

Pros:

• The cell is a genuine Hayward part, which removes the fit and firmware guesswork that comes with generic replacements.
• NSF certification gives a documented performance and safety standard that none of the other nine cells in this list claim.
• At 3.86 lb and 11.7 inches long, it is among the lighter cells here and is easy to handle at the union fittings.
• Buyers report an install of about 10 minutes, with chlorine production starting as soon as the system restarts.

Cons:

• It is rated for 25,000 gallons, so it is undersized for any pool that needs a true T-15.
• Durability is the most common concern, with some owners reporting a lifespan of around two years.
• A few buyers report low chlorine output after installation, which may call for a controller setting check.

Best for: Owners of inground pools up to 25,000 gallons whose existing cell is a T-9 and who want the original-brand part.

The Hayward TurboCell T-Cell-9 is the only cell in this round-up that is not a T-15 style part. It sits at the top because it is the one genuine Hayward unit, with a 15 ft cable and compatibility across AquaRite, AquaRite Pro, SwimPure Plus, AquaPlus, ProLogic, OmniHub and OmniLogic systems. For a pool that already runs a T-9, nothing else here is a like-for-like swap.

The catch is capacity. A 25,000-gallon rating means a 30,000 or 40,000-gallon pool will struggle to hold a sanitizer residual in summer. If your current cell is stamped T-15, skip this one and look at the XHHEZQ T-Cell-15 Titanium Core or the Crispaire T-Cell-15 Salt Cell, both rated for 40,000 gallons.

Longevity is the other thing to weigh. Some buyers report a first cell lasting eight years while the replacement was reported to last closer to two. That is anecdotal, but it suggests treating the cell as a consumable and keeping water balance tight to protect the plates.

2. XHHEZQ T-Cell-15 Titanium Core: Best Titanium-Plate Cell for 40,000-Gallon Pools

• Pool Size: 40,000 gallons
• Plate Material: Titanium core
• Firmware: Control unit revision 1.50 or newer
• Weight: 4.6 lb
• Warranty: 3-year replacement

Pros:

• The titanium sheet construction is pitched at more than three years of service, a longer target than most cells in this list state.
• A 3-year replacement warranty is the longest fixed term among the cells that publish one.
• Compatibility is broad: AquaRite, AquaTrol, SwimPure Plus, OmniLogic, OmniHub, ProLogic and AquaPlus.
• AquaTrol models need no configuration, which makes the swap simple on those systems.

Cons:

• Controllers on firmware older than 1.50 may default to a T-5 or T-15 setting and might need an update.
• AquaRite, AquaRite Pro, ProLogic and AquaLogic units require selecting the T-Cell type through the controller.
• Cable length is not specified, so confirm the reach to your control box.

Best for: Owners of 40,000-gallon pools with a recent controller who want a long-life titanium cell backed by a multi-year warranty.

What sets the XHHEZQ T-Cell-15 Titanium Core apart is its focus on plate life. The maker's pitch is upgraded titanium sheets matching original specifications, with a claimed savings of up to 56% on chlorine costs. At 4.6 lb and 12.8 inches long, it is a close match in size to the Crispaire T-Cell-15 Salt Cell, which weighs 4.7 lb.

The firmware requirement is the part to read carefully. If your control unit is older than revision 1.50, you may need an update before the cell is recognised correctly. On a newer ProLogic or OmniLogic system this is a quick menu change, but on an old AquaRite board it can be the deciding factor.

This is the wrong choice if you want a cleaning accessory or a spare cable in the box, since none are listed. In that case the NYpool T-Cell-15 Kit or the KOONDHEEND T-15 Cleaning Stand Kit gives you more hardware for the same job.

3. Orvex T-15 Upgrade Cell: Best Weather-Protected Cell for Sun-Exposed Equipment Pads

• Pool Size: Up to 40,000 gallons
• Compatible Models: BLT15H, TCELL940, W3T-CELL-15
• Housing: Enhanced external protective layer
• Internal Filter: Upgraded filter chip
• Seals: Leak-proof O-rings included

Pros:

• The external protective layer is designed to resist cracking and degradation from long outdoor exposure.
• An upgraded internal filter chip is meant to catch finer debris before it reaches the electrolytic plates.
• It names three Hayward model numbers (BLT15H, TCELL940 and W3T-CELL-15), which makes cross-checking your old part straightforward.
• Upgraded O-rings are supplied for a clean seal at the unions.

Cons:

• Weight is not specified, so you cannot compare it to the 4.6 lb XHHEZQ T-Cell-15 Titanium Core.
• Warranty length is described only as "robust", with no term given.
• Cable length is not listed, so check your old cell's reach before ordering.

Best for: Owners whose salt cell sits in full sun on an exposed equipment pad and who want extra housing protection.

Check current price on Amazon →

The Orvex T-15 Upgrade Cell competes on build details rather than headline specs. The protective outer layer and the finer internal filter are both aimed at slowing down the two most common ways a cell ends early: housing damage from sun and scale from debris. Dimensions are larger than most rivals at 13.8 by 6.8 by 5.2 inches, which hints at a bulkier shell than the Autopartsfreer T15 Salt Cell.

The upside is a cell that should tolerate weather better than a plain white housing. The TunpLoal T-15 Silver Edition makes a similar UV-resistance claim, so these two are the natural pair to compare for sunny sites.

If you need a documented warranty term or a defined cable length up front, this is the wrong pick. The NYpool T-Cell-15 Kit states a 15 ft cable and a 2-year limited warranty, which fits that case better.

4. Autopartsfreer T15 Salt Cell: Best Plain Titanium-Plate Swap with a 13.5 ft Cable

• Pool Size: 40,000 gallons
• Plates: Titanium electrode plates
• Cable: 13.5 ft
• Weight: 5.14 lb
• Rated Life: 10,000 hours

Pros:

• A 10,000-hour rated life is a clear, comparable figure, well above the 6,000 hours stated for the NYpool T-Cell-15 Kit.
• The box includes two O-rings, a cleaning accessory and an instruction manual.
• Compatibility covers AquaRite, AquaRite Pro, SwimPure Plus, OmniLogic, OmniPL, OmniHub and ProLogic P4.
• A 13.5 ft cable is stated up front, so you can measure before you buy.

Cons:

• At 5.14 lb, it is the heaviest cell in the list.
• The manual calls for software r1.5 or newer, so older controllers need a firmware check.
• The warranty is 1 year, shorter than the 2 to 3 years on several rivals.

Best for: Owners of 40,000-gallon pools who want a documented hour rating and a stated cable length without paying for extras.

Check current price on Amazon →

The Autopartsfreer T15 Salt Cell is the straightforward option: titanium plates, 40,000-gallon rating and a 13.5 ft cable. Its guidance includes keeping total cell run time under 8 hours per day, and that advice applies to any cell in this list.

It is almost identical on paper to the Puyangtego T15 Salt Cell, down to the 10,000-hour rating and 1-year warranty. Choose between them on cell weight and what is included, since the Autopartsfreer states its 5.14 lb mass while the Puyangtego does not.

It is the wrong choice if you want a cleaning stand or a longer warranty. The KOONDHEEND T-15 Cleaning Stand Kit adds the stand and brush, and the XHHEZQ T-Cell-15 Titanium Core extends coverage to 3 years.

5. Crispaire T-Cell-15 Salt Cell: Best Drop-In Cell for Inground and Above-Ground Pools

• Pool Size: 40,000 gallons
• Replaces: W3T-CELL-15, T-CELL-15, Turbo Cell 15, BLW1T15H, GLX-CELL-15
• Electrodes: Reinforced titanium
• Weight: 4.7 lb
• Support: Lifetime warranty and 24-hour U.S. support claimed

Pros:

• It names the widest set of cross-reference part numbers in the list, which helps when matching an old cell.
• NatureSoft is named alongside AquaRite, ProLogic, OmniLogic and SwimPure Plus.
• Cleaning guidance is concrete: a mild acid solution every 3 to 6 months.
• A lifetime warranty is claimed, the longest term of any cell here.

Cons:

• Cable length is not listed, so confirm that your existing connection reaches.
• No cleaning stand or brush is mentioned in the box contents.
• Firmware or cell-type settings are not discussed, so check your controller menu.

Best for: Pool owners who want a stated drop-in replacement with a broad cross-reference and long warranty claims, and are comfortable cleaning the cell themselves.

Check current price on Amazon →

The Crispaire T-Cell-15 Salt Cell leans on compatibility. Its cross-reference list is the longest in the round-up, and it states it is usable on inground and above-ground installs where the system is rated for the volume. At 4.7 lb it matches the XHHEZQ T-Cell-15 Titanium Core closely.

Where it falls behind is paperwork: no cable length, no rated hours and no firmware notes. Pair that with a lifetime warranty claim and the practical advice is to confirm the warranty terms before relying on them.

If you want the firmware requirement spelled out, the XHHEZQ T-Cell-15 Titanium Core or the Autopartsfreer T15 Salt Cell is clearer. For a bundle with cleaning gear, go to the KOONDHEEND T-15 Cleaning Stand Kit.

6. KOONDHEEND T-15 Cleaning Stand Kit: Best Bundled Cell with Cleaning Stand and Brush

• Pool Size: Up to 40,000 gallons
• Included: Cell, pre-attached cable, GLX-CELLSTAND cleaning stand, long-handle brush, O-rings
• Cable: Pre-attached (length not listed)
• Weight: Not listed
• Warranty: 2-year quality assurance with free return and exchange

Pros:

• The GLX-CELLSTAND stand holds the cell upright during cleaning, which frees both hands for the job.
• A long-handle brush is included for loose buildup on accessible surfaces.
• Spare O-rings are supplied, which saves a trip when a union seal fails.
• A 2-year assurance with free return and exchange covers a fit mismatch.

Cons:

• Weight is not specified, so comparisons with the 4.7 lb Crispaire T-Cell-15 Salt Cell are not possible.
• The cable is pre-attached but its length is not stated.
• Compatibility text mentions AquaRite, AquaRite Pro, SwimPure Plus, AquaPlus, ProLogic, OmniHub and OmniLogic, but firmware requirements are not discussed.

Best for: Owners who clean their cell regularly and want the stand, brush and spare seals in the same box.

Check current price on Amazon →

The KOONDHEEND T-15 Cleaning Stand Kit is the accessories play of the list. The stand and brush help with scale management, which is the main reason cells lose output before their plates wear out. That makes it the most practical choice for hard-water areas where cleaning is frequent.

Stick to the cleaning procedure in your pool system manual. Someone who owns an industrial ultrasonic cleaner might be tempted to use it on scaled plates, but a manufacturer-approved method is the safer route for coated electrodes.

If you want a documented hour rating or a stated cable length, the Autopartsfreer T15 Salt Cell is the better fit. The NYpool T-Cell-15 Kit also includes a 15 ft cable and an unclogger.

7. NYpool T-Cell-15 Kit: Best Complete Replacement Kit with 15 ft Cable and Union Nuts

• Pool Size: Up to 40,000 gallons
• Cable: 15 ft
• Included: 4 O-ring seals, 2 union nuts, 1 unclogger
• Rated Life: About 6,000 hours
• Warranty: 2-year limited

Pros:

• The kit includes two union nuts and four O-rings, which suits an install where the old unions are worn.
• A 15 ft cable matches the length on the Hayward TurboCell T-Cell-9.
• A 2-year limited warranty is clearly stated.
• Compatibility is broad: AquaRite, AquaTrol, ProLogic, OmniLogic, AquaRite XL, SwimPure, SwimPure Plus, AquaLogic and AquaPlus.

Cons:

• The 6,000-hour operating life is well below the 10,000 hours claimed by the Autopartsfreer T15 Salt Cell and Puyangtego T15 Salt Cell.
• Some controllers need the T-15 cell type selected in the menu before use.
• At 5 lb and 13.9 inches long, it is on the bulky side.

Best for: Owners who want a complete parts kit with long cable, union nuts and a documented warranty on a residential inground pool.

Check current price on Amazon →

The NYpool T-Cell-15 Kit is the most complete hardware package among the 40,000-gallon cells. Its guidance to use both threaded union nuts is practical: fitting the matching end caps avoids a cross-threaded joint. The unclogger is a small extra that none of the others offer.

The trade-off is cell life. Six thousand hours is the lowest published figure here, so a pool that runs the cell many hours per day will reach it sooner than with a 10,000-hour cell.

If rated hours matter more than kit contents, pick the Autopartsfreer T15 Salt Cell. If cleaning matters more, the KOONDHEEND T-15 Cleaning Stand Kit is the better bundle.

8. Puyangtego T15 Salt Cell: Best Titanium-Plate Alternative with 13.5 ft Cable

• Pool Size: 40,000 gallons
• Plates: Titanium
• Cable: 13.5 ft
• Rated Life: 10,000 hours
• Warranty: 1 year

Pros:

• A 10,000-hour rated life gives it the same long-life claim as the Autopartsfreer T15 Salt Cell.
• Two O-rings, a cleaning accessory and a manual are supplied.
• The 13.5 ft cable length is stated before purchase.
• Guidance on disconnecting power and limiting daily run time to under 8 hours is clear.

Cons:

• Weight is not listed, which makes it harder to compare with other cells.
• The manual requires software r1.5 or newer, so older controllers need verification.
• The 1-year warranty is shorter than the 2 to 3 years on the NYpool T-Cell-15 Kit and XHHEZQ T-Cell-15 Titanium Core.

Best for: Owners who want the same rated life as the Autopartsfreer cell and have already checked their controller's software revision.

Check current price on Amazon →

The Puyangtego T15 Salt Cell reads almost the same as the Autopartsfreer cell: same cable length, same hours, same warranty and the same list of supported controllers. Neither is clearly ahead, so availability and the weight difference are what separate them.

Its product text asks that a qualified professional installs the replacement and that cable reach and connector type are checked first. That caution is sensible for any generic cell, but it does mean this is not the best pick for someone who wants hands-off, tool-free reassurance.

For a longer warranty, step up to the XHHEZQ T-Cell-15 Titanium Core. For more accessories, the KOONDHEEND T-15 Cleaning Stand Kit gives you a stand and brush.

9. TunpLoal T-15 Silver Edition: Best UV-Resistant Housing for Sunny Pool Pads

• Pool Size: Up to 40,000 gallons
• Replaces: T-CELL-15, W3T-CELL-15, GLX-CELL-15-CK
• Housing: Silver finish with UV-resistant shell
• Weight: 2.5 lb
• Extras: Cleaning kit mentioned

Pros:

• The UV-resistant silver shell is aimed at better impact resistance than a standard white cell.
• At 2.5 lb, it is the lightest cell in the list, far under the 5.14 lb Autopartsfreer T15 Salt Cell.
• Compatibility covers AquaRite, ProLogic, SwimPure Plus, OmniLogic and AquaPlus.
• It lists BLT15H among the part numbers it replaces.

Cons:

• Cable length, rated hours and warranty term are all unspecified.
• The weight difference is large enough that buyers should confirm the cell internals match what they expect.
• The cleaning kit is mentioned in the product highlights, but its contents are not described.

Best for: Owners who want a lightweight cell with a UV-resistant shell and are willing to confirm cable reach themselves.

Check current price on Amazon →

The TunpLoal T-15 Silver Edition differs from most rivals in finish: silver instead of white, with a shell built for sun exposure. The Orvex T-15 Upgrade Cell makes a similar durability claim, so for a pad in full sun these are the two to compare.

The key unknown is what lies inside. A 2.5 lb weight is much lower than the other T-15 cells, which sit between 4.6 and 5.14 lb where weights are listed. That may reflect packaging or construction differences, so verify against your old cell.

It is the wrong choice if you want a published warranty or rated hours. The NYpool T-Cell-15 Kit and Autopartsfreer T15 Salt Cell both state those details.

10. Custom Molded Products T-15 Style Cell: Best Spec-Light Backup for 40K Systems

• Pool Size: 40,000 gallons
• Style: T-15 style replacement
• Weight: 3.85 lb
• Dimensions: 14 x 8 x 8 inches
• Cable, warranty and compatibility: Not listed

Pros:

• The 3.85 lb weight is close to the Hayward TurboCell T-Cell-9, so handling is easy.
• It is described plainly as a T-15 style replacement for 40,000-gallon systems.
• The brand name is a specialist in replacement parts rather than a one-off label.
• It avoids long marketing claims, so there is little to second-guess.

Cons:

• No controller compatibility list is provided, so you must verify fit yourself.
• Cable length, rated hours and warranty are all missing.
• Almost no published detail makes it hard to compare against the Crispaire T-Cell-15 Salt Cell.

Best for: Owners who already know their system accepts a generic T-15 style cell and want a minimal-spec option.

Check current price on Amazon →

The Custom Molded Products T-15 Style Cell is the thinnest entry in the round-up. All that is stated is that it replaces a T-15 style cell for 40,000-gallon pools, plus a weight and box size. That is enough to identify it, but not enough to confirm that it suits an AquaRite, ProLogic or OmniLogic board.

For that reason it ranks last. Any of the cells with listed controller compatibility, such as the XHHEZQ T-Cell-15 Titanium Core or the NYpool T-Cell-15 Kit, is a safer buy if you are not sure what your system requires.

Buyer's Guide: How to Choose the Right T-15 Salt Cell Replacement

The core trade-off is certainty against extras. A genuine part removes the doubt over fit, while a generic cell often adds a longer cable, a stand or a broader warranty claim. Every generic cell in this list also puts the burden on you to check firmware and controller settings.

Before choosing, check these project details:

• Pool volume: Match the gallon rating to your pool, since a T-9 is rated for 25,000 gallons and the T-15 cells for 40,000.
• Controller and firmware: Confirm your control unit's software revision, as several cells need 1.50 or newer.
• Cable reach: Measure from the control box to the plumbing, because only some cells state a length.
• Cleaning plans: Decide whether you want a stand and brush or will use your own gear.
• Warranty and hours: Compare stated terms, which range from 1 year to a claimed lifetime.

Pool Size and Cell Rating

The cell rating should match or exceed your pool volume. The Hayward TurboCell T-Cell-9 is rated for up to 25,000 gallons, so it only suits smaller pools. Every other cell in this list is rated for 40,000 gallons, which covers most residential inground pools.

If your pool sits near the top of a rating, running the cell longer each day is the usual workaround. That wears the plates faster, so a 10,000-hour cell like the Autopartsfreer T15 Salt Cell or Puyangtego T15 Salt Cell gives more headroom than the 6,000-hour NYpool T-Cell-15 Kit.

Controller Compatibility and Firmware

Hayward controllers differ in how they identify the cell. The XHHEZQ T-Cell-15 Titanium Core requires revision 1.50 or newer, and the Autopartsfreer and Puyangtego manuals call for r1.5 or newer. AquaTrol models need no setup, while AquaRite, ProLogic and AquaLogic units need the cell type chosen in the menu.

Check this before you order. A cell that is physically correct but set to the wrong type can run at the wrong output, which looks like a failed cell when it is only a setting.

Cable Length and Included Parts

The Hayward TurboCell T-Cell-9 and the NYpool T-Cell-15 Kit both state a 15 ft cable, while the Autopartsfreer and Puyangtego cells state 13.5 ft. The rest do not publish a length. If your equipment pad is far from the plumbing, a stated length removes a common installation problem.

Included parts are the other difference. The KOONDHEEND T-15 Cleaning Stand Kit bundles a stand, brush and O-rings, and the NYpool adds union nuts and an unclogger. A plain cell like the Orvex T-15 Upgrade Cell relies on your existing fittings.

Warranty, Rated Hours and Water Conditions

Warranty terms range from 1 year on the Autopartsfreer and Puyangtego cells to 3 years on the XHHEZQ and a claimed lifetime on the Crispaire T-Cell-15 Salt Cell. Rated hours range from 6,000 to 10,000. These are manufacturer figures, so treat them as a guide rather than a guarantee.

Water conditions decide how much of that life you get. Cold water reduces chlorine production, and a pool with a swimming pool heat pump holds a steadier temperature through shoulder months, which keeps the cell producing for longer. Balanced pH and calcium also slow scale, and cells with a TunpLoal T-15 Silver Edition style shell or an Orvex T-15 Upgrade Cell layer protect against sun, not scale.

Frequently Asked Questions About T-15 Salt Cell Replacements

How Do I Know If My Salt Cell Needs Replacing?

Persistent low chlorine despite correct salt levels, repeated "check cell" or "inspect cell" messages and heavy scale on the plates are the usual signs. Clean the cell first, since scale alone can cause these symptoms. If output stays low after a clean, a new unit such as the XHHEZQ T-Cell-15 Titanium Core or Crispaire T-Cell-15 Salt Cell is the next step.

Can I Use a T-9 Cell Instead of a T-15?

Only if your pool is 25,000 gallons or smaller. The Hayward TurboCell T-Cell-9 is rated for that volume, while T-15 cells like the Autopartsfreer T15 Salt Cell are rated for 40,000 gallons. Using a smaller cell on a larger pool leaves chlorine production short in hot weather.

Do Generic T-15 Cells Work With AquaRite and ProLogic Systems?

Most state compatibility with both, including the NYpool T-Cell-15 Kit and KOONDHEEND T-15 Cleaning Stand Kit. Some controllers need the cell type set in the menu, and several cells need firmware 1.50 or newer. Check your software revision before installing.

How Long Does a T-15 Salt Cell Last?

Stated figures range from 6,000 hours on the NYpool T-Cell-15 Kit to 10,000 hours on the Puyangtego T15 Salt Cell. The XHHEZQ T-Cell-15 Titanium Core targets more than three years of service. Real life depends on water balance, run time and cleaning habits.

How Do I Clean a Salt Cell Safely?

Follow your system manual's approved procedure and disconnect power first. A cleaning stand and brush, as in the KOONDHEEND T-15 Cleaning Stand Kit, make the job easier. The Crispaire T-Cell-15 Salt Cell suggests a mild acid solution every 3 to 6 months.

Is the Silver Housing Better Than the White One?

The TunpLoal T-15 Silver Edition claims a UV-resistant shell with better impact resistance than a standard white cell. That matters most on a sun-exposed pad. It does not change the electrolysis performance, so check the plate and cable specs the same way as for any cell.

Final Verdict: Which T-15 Salt Cell Replacement Should You Buy?

Best T-15 Salt Cell Replacements for most owners of pools up to 25,000 gallons start with Hayward TurboCell T-Cell-9: a genuine Hayward cell, NSF certified, 3.86 lb and supplied with a 15 ft cable. Its main weakness is size, since it is rated for 25,000 gallons and is not a T-15 fit for larger pools.

For a true 40,000-gallon pool, the XHHEZQ T-Cell-15 Titanium Core is the strongest all-round choice, with titanium sheets, a 3-year replacement warranty and a clear firmware note. The Autopartsfreer T15 Salt Cell and Puyangtego T15 Salt Cell suit buyers who want a 10,000-hour rated life and a 13.5 ft cable. The Crispaire T-Cell-15 Salt Cell is the pick when a broad cross-reference and warranty claim matter most.

The specialist picks cover narrower needs. The Orvex T-15 Upgrade Cell and TunpLoal T-15 Silver Edition target sun exposure, the KOONDHEEND T-15 Cleaning Stand Kit bundles a stand and brush, and the NYpool T-Cell-15 Kit adds a 15 ft cable, union nuts and an unclogger. The Custom Molded Products T-15 Style Cell is best kept for buyers who already know their system accepts a generic cell. If you are still undecided, confirm your pool volume and controller firmware first, then choose the 40,000-gallon cell with the clearest published specs.
