## Description

Product Description We Filter Our Drinking Water — But What About Our Shower Water? Meet Weddell Duo — The #1 NSF Certified Shower Filter in Performance* *Based on flow rates and capacity of 2025 wall mount shower filters. Performance You Can Verify Chlorine Reduction Certified by NSF in 2023 Weddell Duo was certified by NSF International to NSF/ANSI 177 and NSF/ANSI 372 standards. PFAS Reduction Verified by IAPMO Lab in 2023 Weddell Duo was verified by accredited IAPMO R&T LAB to NSF/ANSI 42 standard. Particulates Reduction Weddell Duo was verified by accredited IAPMO R&T LAB to NSF/ANSI 53 standard. Not All Shower Filters Are Created Equal Real Filters. Real Results.* *These are actual filters shared by Weddell Water customers — showing the buildup of sediment and contaminants removed from their shower water. Award-Winning Performance Backed by Experts Frequently Asked Questions How often do I need to replace Weddell Duo’s filters? We recommend replacing the full set of Weddell Duo filter cartridges every 5–6 months under standard water conditions for a single user . Actual replacement timing can vary based on the number of people using the shower, your water quality, and household usage patterns. Why am I experiencing decreased water pressure after installing Weddell Duo? Low pressure is usually caused by one of two reasons 1) Installation issue: If the Weddell Duo is not properly aligned with your shower arm, if the O-rings are misaligned, or if too much plumber’s tape was used, it can cause leaks or restrict water flow. 2) Filter at capacity: If your filters are full of sediment and contaminants, you may experience lower pressure. Discoloration of the sediment filter along with a drop in water pressure is a sign it’s time to replace them. Will Weddell Duo soften my water? No. Weddell Duo is a shower filter designed to reduce contaminants such as chlorine, particulates, and PFAS. It does not remove hardness minerals like calcium or magnesium. If you have very hard water, we recommend pairing Weddell Duo with a water softener for the best results. Why are my filters slowing down before the suggested lifespan? Shorter lifespans are typically due to your water conditions. High sediment, hard water, or heavy contamination can cause filters to reach capacity faster than the average 5–6 months. If you notice both sediment discoloration and a drop in pressure, it’s time to replace them — even if it’s earlier than expected. For these situations, we recommend our 3+1 Replacement Cartridges , which include extra sediment filters to help maintain flow and extend the performance of your unit.

Weddell Duo combines proprietary activated carbon and multi-stage condensed layers to effectively remove chlorine, PFAS, particulates, and unpleasant odors from your water. The result? Water that feels and smells cleaner, leaving your skin, scalp, and hair noticeably healthier.
- Why Filtered Water Matters - Unfiltered water can contain harmful contaminants like chlorine, PFAS, and microplastics, which may lead to skin dryness, irritation, and scalp problems.

Observe the filtration process through the clear dual cartridges, then twist to remove and replace when needed.

## Questions & Answers

**Q: How long I can use this shower filter?**
A: In general, you can use our Duo for six months. But the exact answer will depend on (1) how long and often you (and your family) take a shower and (2) the faucet water quality of your area.  Another easy self-checkpoint to replace the filter cartridge can be your own visual check to see how much your filter cartridge collected impurities as in our video, or dramatic shower water pressure drops due to the impurities caught by the filter.

Our filter cartridge refill package product shall be added within a few weeks from now. Hope this answers your question. Thank you again.
