All Filters offers a comprehensive selection of replacement RO membranes, carbon filters, and sediment cartridges for hydroponic and controlled environment agriculture systems. Our SpiroPure brand delivers 30–50% cost savings compared to OEM filters while maintaining NSF-certified quality standards in carbon block and membranes. SpiroPure filters are compatible with many major water treatment systems, ensuring proper fit and reliable operation.

Our replacement products help growers maintain consistent water quality for optimal plant health and yields. Whether operating a small hydroponic setup or managing a large-scale vertical farm, proper filtration removes chlorine, chloramines, and contaminants that affect nutrient uptake and root development. Here are some more benefits from All Filters:

  • RO Membrane Performance: Choose commercial membranes in 2521, 2540, 4021, and 4040 or 8040 sizes for large-scale facilities to tackle a range of chemicals and dissolved solids that interfere with precise nutrient control and plant health.
  • Pre-Filter Protection: Carbon filters remove chlorine and chloramines that damage beneficial microbes and root systems, while sediment cartridges protect against particulates that clog irrigation emitters and foul RO membranes. Regular pre-filter replacement every 3–6 months extends membrane life and reduces operating costs.
  • Cultivation-Ready Ordering: Many of our filters work with popular hydroponic and irrigation systems and replace major brands at pricing that protects your margins. Most orders leave our warehouse the same day and include free shipping over $99. Super Value deals on pre-filter packages let you maintain consistent water quality throughout growing cycles.
  • Our friendly and knowledgeable customer service team is available seven days a week to provide individualized advice so you can find the right product. Or contact our sales manager with questions about pricing.
