RO3 aquarium filter cartridge set (reverse osmosis): carbon WWL2, sediment WPL2, and Teflon tape for sealing threads. Coconut carbon helps remove chlorine and organic compounds, while the polypropylene cartridge traps solid particles. Plug-and-play cartridges fit standard RO3 modules.
The WPL2 WWL2 FILTER SET + Teflon tape for the RO3 filter is a practical service kit for an reverse osmosis system used in aquarium setups. The set includes two key filter cartridges for pre-filtration and Teflon tape for sealing threaded connections. It is a convenient solution for users who want to maintain high performance, an efficient water filtration system, and trouble-free installation in an osmosis filter RO3 unit.
The set combines mechanical and carbon filtration: the WPL2 sediment cartridge traps solid particles, while the WWL2 carbon cartridge with coconut shell carbon helps reduce chlorine and organic compounds. Thanks to the plug-and-play design, the cartridges fit standard RO3 modules, making regular operation and replacement of elements in the reverse osmosis system easier.

This set has been prepared with convenient maintenance of the RO3 aquarium filter in mind. Instead of selecting parts separately, you receive a ready-made set including the basic cartridges for pre-treatment and Teflon tape useful when sealing threads.
This solution works well wherever quick servicing, maintaining correct system operation, and convenient replacement of consumable parts in a water treatment system based on reverse osmosis matter.
The polypropylene cartridge, also referred to as a sediment cartridge, is responsible for trapping solid particles present in the water. Its task is to limit the passage of mechanical impurities to the next stages of the system.
The carbon cartridge with coconut shell carbon supports the reduction of chlorine and organic compounds. This is an important pre-filtration stage in RO3 systems that helps prepare the water for further reverse osmosis filter operation.
The included Teflon tape is used to seal threaded connections. It facilitates correct installation and helps reduce the risk of leaks during servicing or replacement of elements.
To maintain proper operation of the water filtration system, the cartridges should be replaced regularly according to the adopted service schedule. During installation, threaded connections should be carefully sealed with Teflon tape and the system should be checked for tightness after startup.
The cartridges are made in a plug-and-play format, which means they are intended for standard RO3 modules. This is a practical feature that simplifies operation and shortens the time needed to replace consumable elements.
The set is designed for the RO3 aquarium filter operating as a reverse osmosis system. Proper sizing and connection compatibility make it easy to use the cartridges in typical configurations of this solution.
Regular replacement of the pre-filters is important for stable operation of the entire system. The sediment filter takes over mechanical impurities, while the carbon filter helps limit substances that affect water quality and the performance of the later filtration stages.
The set works well as a convenient service kit for periodic maintenance of the device. This gives the user the elements necessary both for pre-filtration and for proper sealing of connections during installation.

The set is designed for the RO3 aquarium filter operating in a reverse osmosis system. The plug-and-play cartridges fit standard RO3 modules.
The set includes three items: the WWL2 carbon cartridge, the WPL2 polypropylene/sediment cartridge, and Teflon tape.
WPL2 is a polypropylene sediment cartridge whose task is to trap solid particles present in the water. In this way, it helps protect the next elements of the filtration system.
WWL2 contains coconut shell carbon and helps remove chlorine and organic compounds from the water. This is an important pre-filtration stage in the RO3 system.
The Teflon tape is used to seal threaded connections. It helps achieve a tight installation and reduces the risk of leaks after replacing the cartridges.
The dimensions are approximately 55 mm in diameter and approximately 250 mm in length.
The expected service life of the cartridges is up to 6 months. In practice, the replacement frequency should be adjusted to operating conditions and water quality.
The operating temperature range is from 2 to 42 °C.
The cartridges have 2 connections with 1/4″ female thread, which corresponds to approximately 14 mm.
Compatible devices and housings.
