Keep your undersink RO performance crisp and consistent

The iSpring F3 6-Month Prefilter Pack is designed for most standard undersink RO filtration setups. It offers a ready-to-install trio of filters that work together to reduce particulates and enhance water quality at the tap.

What’s included

  • Three 10" x 2.5" filters: a sediment filter, a granular activated carbon (GAC) filter, and a carbon block filter.
  • Six-month capacity designed for typical home usage with standard RO systems.

How these filters support your water system

  • Sediment filter traps particles before they reach other stages, helping to maintain flow and reduce visible turbidity.
  • GAC filter targets taste and odor, potentially giving water a fresher, cleaner profile.
  • Carbon block filter adds an additional stage of contaminant reduction and improves overall water clarity.

Note: This filter pack DOES NOT include an RO membrane. It focuses on prefilter stages to support filtration performance.

Everyday benefits you might notice

  • Smoother pour and clearer glass of water as particulates are filtered earlier in the process.
  • Cleaner tasting water with reduced odors at the point of use.
  • Potentially longer life for your RO membrane by filtering more at the prefilter stage.

Installation and maintenance

If you have trouble installing the filters, please refer to the user manual or contact our support team for guidance. Regular checks and timely replacements help you maintain steady faucet flow and water quality.

Why choose iSpring F3?

  • Designed for easy replacement in most standard RO setups
  • Includes three 10" x 2.5" filters for ongoing prefiltration
  • Six-month capacity offers a practical maintenance cycle for many homes
