Bullfrog Filter Cartridges
Bullfrog replacement filter cartridges — in stock now and shipped fast Australia-wide from HASP, home to Australia’s largest range of spa and pool filter cartridges in a huge variety of sizes and styles.
New cartridges are added and updated all the time, so not every filter we stock is shown on this page. Can’t see yours? Use our Pool & Spa Filter Cartridge Finder to search by length, diameter, end-cap type, hole size, thread size or spigot size — or send us the measurements and we’ll match it for you.
We physically stock more filters than most online retailers, which means faster shipping and convenient local pick-up — without the delays that often come with drop-shipping websites.
Many spa and pool filters are rebranded under different part numbers, so our filter search tool is often the easiest way to identify the correct replacement.
All of our filters are made by Darlly, Magnum or their approved OEM manufacturers, using trusted materials such as Darlly, Reemay and Magnum media. We do not sell low-grade eBay, Wish, Temu, Chinese, Technix filters or generic copies — our focus is on quality, fit and reliable filtration.
How to identify the right replacement cartridge
Match your cartridge by its physical measurements rather than the printed part number alone: overall length, outside diameter, and the end-cap style (open hole, internal thread, or spigot). The same element is frequently re-badged across brands and part numbers, so measuring is the surest way to confirm a fit — or let our finder do it for you.
Frequently asked questions
- I can’t see my filter listed — what now?
- Our range changes constantly and not every cartridge is shown on each brand page. Measure your cartridge (length, outside diameter and end-cap style) and match it in our Pool & Spa Filter Cartridge Finder, or send us the dimensions and we’ll find it for you.
- Are these genuine, OEM-quality cartridges?
- They are OEM-grade replacement cartridges manufactured by Darlly, Magnum or approved OEMs, using Reemay and Magnum filter media. We do not stock cheap generic copies.
- Do you ship Australia-wide and offer local pick-up?
- Yes — stock is held physically across our VIC, NSW, QLD and WA warehouses for fast nationwide dispatch, with local pick-up from our Carrum Downs showroom in Melbourne.
Cartridges in this range suit a wide range of pool and spa equipment, including SpaPro and WWDG systems and many rebranded equivalents. Need help confirming a fit? Our team can match your old element by measurement.
