I have found they last a long time before needing to be changed. Maybe try another filter and see what happens. Thoroughly clean everything first. **Q: I just received my filters on august 4. by august 6 the tester reads 16. is this defective filter? there is only one person in household.** A: The filter normally works between 3-4 months for myself, 2 months when my son is home from college. A failure so quickly can be caused by a number of things; the filter may not be seated in the holder correctly, the filter may not be tightened or the fulfillment company damaged the product before shipping but shipped it anyway. Yes the last one did happen. **Q: Does it contain coconut shells?** A: I didn't see any coconuts. I have no idea what you are driving at. Coconut shells? Am I missing something? **Q: Whats the difference between the zr-004 filter and the zr-006 filter besides 15 dollars?** A: Not much 'Google' info available about this, but on the ZeroWater FAQs page, someone asked what the difference was between ZR-001 and ZR-017, and ZeroWater responded with 'just the quantity is different'. ## Customer Reviews ### ⭐⭐⭐⭐⭐ will buy again *by T***Y on 5 January 2026* ### ⭐⭐⭐⭐⭐ Water droplets are normal and are from final testing of product. *by W***R on 3 October 2025* ### ⭐⭐⭐⭐⭐ Makes water taste healthy. *by J***S on 19 December 2025* ## Frequently Bought Together - ZeroWater 4-Pack Replacement Filter Cartridges ZR-004, 4 Count (Pack of 1), Basic pack - ZeroWater 12-Cup Ready-Pour 5-Stage Water Filter Pitcher 0 TDS for Improved Tap Water Taste - IAPMO Certified to Reduce Lead, Chromium, and PFOA/PFOS - ZW2 TDS Meter, Replacement for Zerowater ZT-2 Water Tester, Blue --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/342214246-zerowater-replacement-filter-cartridges-zr-004-by-zerowater](https://www.desertcart.us/products/342214246-zerowater-replacement-filter-cartridges-zr-004-by-zerowater) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-25*
