Osmosis filters and accessories for indoor growing
Irrigation with osmosed water guarantees a supply free of chlorine, salts, and heavy metals, allowing plants to absorb nutrients more efficiently and grow healthier. On this page, you will find various accessories and replacement cartridges adaptable to most reverse osmosis systems.
Granular Activated Carbon Cartridge (UDF)
The UDF granular activated carbon cartridge is specifically designed to remove chlorine, organic matter, color, and odors from water. This pre-filter extends the lifespan of the osmosis membrane and directly improves the quality of the water your crop receives.
Activated carbon filters can effectively remove chlorine, organic compounds, and even improve the health of the filtration system.
The benefits of using this cartridge are reflected in irrigation with pure and balanced water, free of residues that alter pH or conductivity. Thanks to this, plants absorb nutrients better, reduce water stress, and develop a more vigorous, healthy, and productive structure.
Main features of the granular activated carbon cartridge (UDF)
- High adsorption granular activated carbon.
- Extruded structure for pressure drop stability and long lifespan.
- Compatible with standard 10″ to 20″ housings.
- Reduces odor, chlorine, and organic compounds that can affect the crop.
Activated Carbon Cartridge Filter (CTO)
The CTO (Carbon Block) replacement is an antibacterial block activated carbon filter, designed as a second filtration stage after sedimentation or granular filtration. It removes fine particles, taste, odor, and residual chlorine structure or volatile compounds.
The benefits of incorporating this second filtration phase are evident: water reaches the irrigation system with a neutral taste and no residues, preventing the accumulation of sediments or compounds that could alter nutrient absorption. The result is more balanced, cleaner, and more efficient plants in their development.
Main features of the activated carbon cartridge filter (CTO)
- Extruded activated carbon block with a 10 µm filtering polypropylene wrap.
- Compatible with standard 10″ cartridge holders.
- Designed to stop fine particles and neutralize odor and taste.
5 Micron Sedimentation Cartridge
The sedimentation cartridge acts as an initial filter for solid particles, sand, rust, or sediments present in the water. It is a key stage to protect subsequent stages of the reverse osmosis system.
The benefits of this sedimentation filter are clear: by previously removing solid particles, sand, or rust, it prevents the carbon or membrane stages from clogging or deteriorating prematurely, reducing maintenance and ensuring more stable and safer water for the crop.
Main features of the 5 micron sediment cartridge
- Made of polypropylene (PP) or similar materials, 5 µm version, compatible with domestic systems.
- Progressive density layer structure: outer layers trap large particles; inner layers, finer ones.
- Easy installation and replacement.

The sediment filter is essential so I don't ruin the membrane before its time. The grow really appreciates it.
Translated from Spanish
Imprescindible el de sedimentos para no cargarme la membrana antes de tiempo. El cultivo lo agradece.

You can really tell the difference in the roots, the plants absorb everything better since I changed the filters.
Translated from Spanish
Se nota mucho la diferencia en las raíces, las plantas absorben todo mejor desde que cambié los filtros.
