Eco Grow 240 L/H GROWMAX water filter is a compact two-stage unit designed to purify water intended for indoor cultivation. It removes chlorine and reduces organic and inorganic contaminants, providing a stable and uniform supply for irrigation systems and preparation of nutrient solutions when watering indoor crops, without electricity consumption or water waste.

This dual filtration system combines a sediment pre-filter and an activated carbon cartridge in a ready-to-mount format, offering a constant flow rate of 240 L/h for intensive production spaces.
The first stage retains particles larger than 5 microns (sand, soil, oxides), protecting valves, drippers, and irrigation accessories from clogging.
The second stage adsorbs up to 99% of chlorine and reduces unwanted compounds such as herbicides, pesticides, and volatile organic contaminants (benzenes, oils, trihalomethanes, detergents, PCBs), significantly improving the smell and taste of the water and reducing chemical reactions with fertilizers.
Thanks to its design, it works without electricity, without minimum pressure, and without water waste, features highly valued when seeking efficiency and sustainability indoors.
Total filtered capacity reaches 11,000 liters per set of cartridges under standard conditions, with basic maintenance and periodic replacement according to consumption and input water quality. Installation is straightforward: connect to the network, purge, and it is operational in minutes.
The robustness of the set and its practical approach make it an ally for those who want uniformity in fertigation and lower risk of precipitates or biofilm in irrigation lines.
In indoor growing water quality makes the difference. Eco Grow 240 L/H GROWMAX Water Filter stabilizes parameters, reduces reactive compounds, and helps keep drippers and hoses in good condition. The result is more predictable nutrient mixes, vigorous roots, and productive cycles with fewer incidents.
Its purpose is to remove chlorine, retain sediments, and reduce herbicides, pesticides, and VOCs. It serves to protect the irrigation system, safeguard compatibility with fertilizers, and improve consistency in watering indoor crops. It also helps reduce scaling, blockages, and unplanned maintenance.
Works perfectly with pressure regulators, non-return valves, tanks, pumps, and micro-drip. By entering the pre-treatment train, it extends the life of irrigation accessories and keeps the hydraulic network cleaner, which is key when operating tables, trays, and irrigation rings over many consecutive cycles.
Startup is simple: fix the bracket, connect the inlet and outlet, open the water supply, and purge for a few minutes until a clear, bubble-free flow is obtained. From there, it supplies up to 240 L/h under typical domestic conditions. Recommended maintenance: visual inspection, external cleaning of housings, and cartridge replacement according to actual consumption and water quality; as a practical reference, the set yields up to 11,000 L total. If you notice signs such as reduced flow, return of chlorine odor, or color changes, plan for replacement. It does not require electricity or minimum pressure, so it can be integrated into both pressurized lines and pump-assisted configurations.
Competitive price considering savings on fertilizers, membranes, and irrigation spare parts, as well as reduced maintenance. There are packs with replacement cartridges that optimize the cost per filtered liter.
