Pool & Spa Filter Cartridge Finder v0.95b

Having trouble finding the right filter for your pool or spa? Use our exclusive Search Tool!

Just measure it, click the images, and search by size, end openings and end-cap type to find likely Darlly, Magnum, or other replacements. Results are possible matches ranked by closeness — always verify the match on the product listing before ordering.

If you have any issues, please contact us at info@hasp.com.au

How to find the right pool or spa filter cartridge

To identify a replacement pool or spa filter cartridge, measure the overall length, the outside diameter, the top end style, the bottom end style, the hole opening size and any thread or spigot size. Enter those measurements into the filter finder below to see the closest matching replacement cartridges.

If your old filter has a faded label, no part number, or has been rebranded under another spa or pool brand, measuring the cartridge is usually the most reliable way to find a replacement.

1 How to measure & identify your cartridge

How to measure a pool or spa filter cartridge by length, outside diameter, hole size and end-cap style

Overall length: measure end to end, including the end caps.
Outside diameter (OD): measure across the pleated body at its widest point.
Top end: note whether it is open, closed, has a handle, is threaded, or another style.
Bottom end: note whether it is open, closed, threaded, spigot-style, or another style.
Hole opening: measure the inside diameter of any centre opening, in millimetres.
Thread or spigot: measure the outside diameter of any thread or raised spigot, in millimetres.

Darlly, Magnum, & OEM Pool & Spa Filter Cartridges

HASP carries Australia’s largest physical range of pool and spa filter cartridges, with Darlly, Magnum, and other OEM high-quality filters available across a huge range of common replacement sizes.

Darlly & Magnum are some of the world’s largest OEM filter cartridge manufacturers, producing filters for pools, spas, drinking water systems, and industrial water filtration.

Both Darlly & Magnum manufacture filters that are commonly rebranded and supplied under many well-known pool and spa brands, including AstralPool, Davey, Emaux, Filtrite, Halo, Hayward, Madimack, Pentair, Poolrite, Poolwerx, Sapphire, Waterco, Zodiac and many others. In many cases, the filter inside the box is made by Darlly or Magnum, even when sold under another brand name.

What’s different about our filters from others?

Our filters are literally the same filters used in many major brands.
We offer great prices, for high quality.
We offer the largest range of filters, and keep the most physical stock.
These are not the cheap, low-grade filter copies often found on eBay, Wish, Temu, Amazon and other online sellers.

Find replacement filters by size, brand or part number

This tool helps with searches such as:

spa filter cartridge by size
pool filter cartridge replacement by measurement
Darlly filter cross reference
Magnum filter cartridge equivalent
replacement spa filter with no part number
filter cartridge with a threaded bottom, a handle top, or open holes top and bottom
replacement filters for AstralPool, Zodiac, Davey, Hayward, Waterco, Pentair, Poolrite, Sapphire, Emaux, Madimack and other brands

Pool & spa filter end-cap types explained

Cartridges are matched not only by length and outside diameter — the top and bottom end styles matter just as much. A filter with the right length but the wrong end cap may not seal, lock in, or fit the housing correctly.

Open hole end

An open-hole end has a round opening through the centre of the cap. Measure the inside diameter of the opening in millimetres.

Closed end

A closed end has no centre opening. Some closed ends include a handle or raised moulding.

Handle top

A handle top makes the cartridge easier to remove. The handle shape must clear the filter housing lid.

Threaded bottom

A threaded bottom screws into the housing. Measure the outside diameter of the thread, and check the product listing carefully before ordering.

Spigot bottom

A spigot bottom has a raised male fitting that pushes into the housing. Measure the outside diameter of the spigot in millimetres.

Part number search vs measurement search

If your filter still has a readable part number, searching by part number is usually fastest. If the number is missing, faded, or from a rebranded cartridge, searching by measurement is usually more reliable.

Darlly & Magnum vs rebranded spa filters

Many spa and pool filters are manufactured by large OEM makers such as Darlly and Magnum, then sold under different brand names. A replacement can match by measurement even when the brand printed on the old filter is different.

Why length and diameter alone are not enough

Two cartridges can share a similar length and diameter but have different end-cap styles. Always check the top end, bottom end, hole opening and thread or spigot size before ordering.

Pool & spa filter cartridge finder FAQs

Can I find a spa filter without a part number?

Yes. If the part number is missing or faded, measure the old cartridge by overall length, outside diameter, end-cap type, hole size and thread or spigot size. Those measurements can be used to find likely replacement filters.

Are Darlly and Magnum filters used under other brand names?

Many pool and spa filter cartridges are manufactured by OEM makers and then rebranded by pool and spa companies, which is why measuring the cartridge is often more reliable than relying only on the brand printed on the old filter.

What if my measurements are slightly different?

Cartridge measurements can vary slightly due to age, swelling, manufacturing tolerance or measuring method. Use the closest match, but always check the product listing before ordering.

What measurements matter most?

Overall length, outside diameter, top end style, bottom end style, hole opening size, and thread or spigot size.

Can I use a pool filter cartridge in a spa?

Only if the dimensions, end-cap style, flow requirements and housing requirements are correct. Do not choose by appearance alone.

Manufacturer Catalogues, Diagrams & Part Numbers

Need exploded views, spare part numbers, product numbers, diagrams, or more product information? See the manufacturer catalogues: AstralPool Catalogue 2026 | Zodiac Catalogue 2026

In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.

Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:

Imperial Name	Metric Name	Pipe Diameter (OD)
1/2"	15mm	~21.2–21.5 mm
3/4"	20mm	~26.6–26.9 mm
1"	25 mm	~33.4–33.7 mm
1.5"	40 mm	~48.1–48.4 mm
2"	50 mm	~60.2–60.8 mm
2.5"	65 mm	~75.2–75.5 mm

These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions^1.

º Internal diameters vary slightly by manufacturer and class.
¹ Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.

Understanding Plumbing Sizes & Nominal Measurements

Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.

Quick example: A 2" / 50 mm fitting is named for the pipe it connects to, but the pipe’s actual outside diameter (OD) is approx. 60.3 mm (typically ~60.2–60.5 mm in AS/NZ pressure pipe).

Why pipe sizes don’t match the measurements

The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.

How to Measure Pipe Correctly

Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).

Important: For pool/spa work, most plumbing uses Pressure Pipe (AS/NZ standards) — not DWV. Always check OD and the pipe class against your equipment specifications.

Hose & Tube Dimensions

Common flexible hose sizes used in pool/spa systems (approximate IDs).

Imperial Name	Metric Name	Inside Diameter (ID)
3/8"	9–10 mm	~9 mm
3/4"	19 mm	~19 mm

BSP – British Standard Pipe Thread Sizes

BSP thread names are also nominal. The thread OD will not equal the nominal name.

BSP Thread Size Naming	Outside Diameter (mm / inch)	TPI
1/16" BSP	7.7 mm / 0.304"	28
1/8" BSP	9.7 mm / 0.383"	28
1/4" BSP	13.16 mm / 0.518"	19
3/8" BSP	16.66 mm / 0.656"	19
1/2" BSP / 15 mm	20.99 mm / 0.825"	14
5/8" BSP	22.99 mm / 0.902"	14
3/4" BSP / 20 mm	26.44 mm / 1.041"	14
7/8" BSP	30.20 mm / 1.189"	14
1" BSP / 25 mm	33.25 mm / 1.309"	11
1-1/4" BSP	41.91 mm / 1.650"	11
1-1/2" BSP / 40 mm	47.80 mm / 1.882"	11
2" BSP / 50 mm	59.61 mm / 2.347"	11
2-1/4" BSP	65.71 mm / 2.587"	11
2-1/2" BSP	75.18 mm / 2.960"	11
3" BSP	87.88 mm / 3.460"	11
4" BSP	113.03 mm / 4.450"	11
5" BSP	138.43 mm / 5.450"	11
6" BSP	163.83 mm / 6.450"	11
