Weddell Duo Shower Filter Replacement Cartridges

  • Welcome to step zero of your self-care routine! Weddell Duo combines proprietary activated carbon and multi-stage condensed layers to effectively remove chlorine, PFAS, microplastics, 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. Long-term exposure to these pollutants has been linked to potential health risks, including hormonal disruption and skin conditions. By filtering these out, Weddell Duo ensures you experience cleaner, healthier water for a noticeable difference in your skin, hair, and overall well-being.
  • #1 in NSF Certified Performance: Weddell Duo is the #1 NSF Certified Shower Filter for Performance, based on flow rates and capacity among 2024 wall mount shower filters. Weddell Duo is the only shower filter to be NSF certified for reducing Free Available Chlorine while maintaining a verified reduction in PFAS and microplastics.
  • Easy Installation & Broad Compatibility: Weddell Duo is compatible with various shower heads—rain, fixed, or handheld. Installation is tool-free and quick! Just tighten the swivel connector and reattach your shower head in minutes. It's perfect for homes, dorms, travel, and pets, effectively reducing hair dryness, skin irritation, and unpleasant odors.
  • Simple Replacement & Cost-Efficient: Unlike most filters that are hard to replace, Weddell Duo's filters are side-mounted, allowing easy monitoring of their condition. Observe the filtration process through the clear dual cartridges, then twist to remove and replace when needed. Each filter set lasts up to 8,000 gallons, offering a cost-effective solution for long-term clean water.

Great product

The Weddell Duo shower filter is amazing. Not only do we know that we are filtering the toxins from the water we also notice the clear difference in our skin and hair. Great product! Thanks Weddell!

Good!

Definitely notice a difference with mineral buildup on the shower hardware when it's new vs old, so must be doing something. For me, the filter probably lasted around 60 days before there was a significant decrease in water pressure. By significant I mean like 2/10 water pressure.Installation: 10/10. Super easy. Just twist to remove.Price wise is okay. I have a Korean one in the other shower, which is just a carbon filter + vitamin c and they're on the same price range. But it doesn't decrease water pressure so I feel like I can go a little longer with it before replacing.

Hey, this is certified, while others are self-claimed. What else I need?

The frustration I had when I tried to find a good shower filter is I cannot judge their claims by myself as an ordinary consumer. I wonder who else can precisely. But when I found this project, it simply said "Wow", because this product is fully certified and verified by industry-leading organizations such as NSF and the 100-year-old lab. To make this better, I was able to transparently see what's going on inside the shower filter cartridge. And the filter cartridge replacement is a piece of cake in heaven. What else I need than this?I am little puzzled at the complains on the review about the water pressure drop. I also saw it dropped, but I'd rather glad to see the drop, because it is the untouchable proof the filter cartiridge is actually "working". This is why I happily gave up using self-claimed products that I cannot judge by myself and started using this.Hope this helps.

Water pressure does not decrease

It continues to function for several months without reducing water pressure.
