We recommend keeping it at a slower flow rate to allow enough contact time with your water as it will provide better filtration. Hope this helps. **Q: Does it remove iron?** A: I don’t have horrible iron problems but it definitely took the iron out. **Q: Is this a refillable cartridge?** A: Yes, this filter is but the other filter is washable, so you only replace this one! **Q: What is the filter lifespan in gallons , not time?** A: The filter lifespan in gallons can vary based on the water conditions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Water filter *by A***R on July 17, 2026* Great filter and price ### ⭐⭐⭐⭐⭐ Filters for low level Arsnic and other heavy metsls. *by P***R on December 3, 2025* Replacement for prior filters.
