Description
Upgrade your spa or pool filtration with the Darlly Spa/Pool Replacement Filter Cartridge set. Built for 90 sq ft of filtration, these cartridges are the ideal replacement for systems that accept 60402/60403 formats. Each cartridge measures a 6" outer diameter and 8-1/4" in length, delivering robust performance in compact housings designed for ease of maintenance.
Key features that keep water clean and running smoothly
- 90 sq ft filtration per cartridge for extended cleanings between replacements, helping you maintain crystal-clear water with less downtime.
- 6" outer diameter & 8-1/4" length (compact yet high-capacity) to fit standard spa and pool filter housings.
- Top: open slip connection 1-3/4" for straightforward installation and a secure seal.
- Bottom: 1-1/2" SAE threaded to match common filter fittings, ensuring compatibility with many spa/pool systems.
- Media: 3 oz per cartridge of durable filtration media designed to trap dirt and debris while allowing good water flow.
- Semi-circular end caps on both ends provide a confident grip during installation and cleaning.
- Includes two cartridges in the set (PWW100P3-SET), offering convenient, cost-effective replacement for ongoing maintenance.
- Manufacturer: Darlly Manufacturing with model alignment to 60402/60403 applications for spa and pool systems.
Why this matters for your water quality: the combination of a generous 90 sq ft filtration area and a rugged 3 oz media layer means more particulates get trapped before they recirculate, resulting in clearer water and less frequent backwashing. The compatible 1-1/2" SAE bottom thread and 1-3/4" top slip design simplify alignment with common filter housings, reducing installation guesswork and downtime.
Ideal use cases
- Replacing worn or worn-out cartridges in spas and above-ground pools that use the 60402/60403 format.
- Two-cartridge configurations for seasons of heavy use or for systems that require consistent filtration with minimal maintenance interruptions.
- Renovating water features that demand reliable, high-capacity filtration without frequent cartridge changes.
Installation and care tips
- Power down the spa or pool filtration system before servicing.
- Remove the old cartridge and rinse the filter housing to clear debris.
- Rinse the new Darlly cartridges under clean water, removing any packaging residue before installation.
- Insert the cartridges with the top slip connection and bottom SAE threads aligned with the housing fittings; ensure a snug, even seal.
- Run the system and check for leaks. If flow seems reduced, gently rinse the cartridges again to restore optimal filtration.
Designed for reliability and ease of use, this two-pack of Darlly replacement cartridges for spa and pool filtration is a practical, long-term choice for maintaining clear water and consistent system performance. Whether you’re refreshing an aging setup or stocking up for routine maintenance, the 90 sq ft cartridges (6 x 8.25) with 1-1/2" SAE bottom threads are a dependable match for compatible filter housings.
