Description
Maytronics 9991408-R4 Spring Filter Cartridge 4/Pack
The 9991408-R4 is a genuine OEM replacement kit of four spring-cartridge filter panels designed for select Maytronics/Dolphin robotic pool cleaners. These panels are engineered to capture larger debris during heavy-load cleaning cycles (such as spring openings or leaf-fall seasons) and allow finer particles to pass through, helping prevent premature clogging and maintaining flow.
Key Features
Includes 4 individual filter panels in a single package—enough to replace the full set in compatible cleaner models.
Spring-cartridge design that prioritizes capturing larger debris while maintaining smoother flow of finer particles, reducing clogging under heavy debris loads.
Durable construction using pool-rated materials suited to repeated wet/chemical exposure, built to perform under continuous robotic cleaner operation.
OEM part from Maytronics → designed for direct-fit installation with compatible models.
