The best bag or cartridge size depends on your system requirements and replacement frequency. Larger cartridges or bags reduce the frequency of replacements and are ideal for commercial or high-volume users, while smaller sizes offer flexibility, portability, and are easier to handle for lighter or occasional use. Having access to various sizes allows you to customize your resin supply to your system’s needs, saving time and reducing costs. For example, ProTool DI Cartridge (RTU) 20in for Eco Cart is designed for Eco Cart systems, while ProTool DI Filter 4.5in x 10in Blue/White RTU fits many different carts with a 10 in filter. HydroPower Ultra 1-Stage Replacement Resin (3 Pack) offers conveniently sized packs for quick swaps. Numerous size options are available to fit every system and user preference.
