10 GROWMAX Replacement Filter Pack designed to keep water clean and stable in indoor cultivation. 10" cartridges that improve equipment performance, reduce chlorine, sediments >5 µm and multiple contaminants. Approximate lifespan of 11,000 L per set. Available at Hydroponics Blanes, online grow shop with discreet shipping.

The 10 GROWMAX Replacement Filter Pack ensures an effective pre-treatment stage for filtration and reverse osmosis systems aimed at technical horticulture. The usual combination of sediment cartridge (retention of particles of ≥5 microns) and granular or block activated carbon cartridge facilitates the removal of chlorine up to 99 %, as well as adsorbing compounds that deteriorate RO membranes and affect plant development: herbicides, pesticides, VOCs (benzene, oils, toluene, trihalomethanes), detergents and PCB.
The improvement in water quality results in less scaling of lines, drippers and pumps, and a more homogeneous starting point for preparing A/B nutrients.
Each 10" set yields around 11,000 liters —reference value that may vary depending on input TDS and turbidity—, so it is advisable to audit with a TDS/EC meter and check pressure drop to schedule replacement.
Thanks to standard connections of transparent or opaque housings, replacement is quick in any manual or automated irrigation system.
Integrated with graduated tanks, pumps and irrigation accessories, this pack keeps the installation stable and helps to water indoor crops consistently.
In indoor growing spaces, water quality determines pH stability, substrate response and cleanliness of pipes. The 10 GROWMAX Replacement Filter Pack reduces particles that clog drippers and retains chlorine that harms beneficial microbiota, promoting healthy roots and more predictable recipes. Proper pre-treatment also extends the life of RO membranes and reduces maintenance intervals in the irrigation room.
The installation gains reliability when complemented with 10" housings with vent, pressure gauges before and after the filtration train to detect pressure loss, non-return valve and TDS/EC meter to audit quality. In the irrigation circuit, graduated tanks, submersible pumps according to flow rate, 8–12 mm hoses, final line filters and flow meter to standardize liters per plant help. All available at Hydroponics Blanes, trusted Grow Shop with discreet shipping.
Operational tip: use labels on housings with “stage 1/stage 2” and note accumulated liters or weeks of use. This control simplifies replacement purchases and keeps the irrigation system within parameters.
