Better water, better self-care. We design products that put your health and well-being first while giving back to our community.
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, 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. 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 particulates.
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.

I will never have dry skin again!
Omg! Love this shower filter. My arms and legs were always so dry. That changed after one use.Easy to install. It might hinder the water flow a little, but nothing to complain about.

Ok- this is one THAT ACTUALLY WORKS!
Okay. I knew my water was heavy with chlorine and gosh knows what else! I have sensitive skin and highly allergic to chlorine and chemicals of all kinds. This filter has not only saved my skin but my hair is growing again! WOW. I have hard water and that isn’t going to change but this product is great value and actual works. I have also tried another major seller/competitor to this product and there is no match to this one. The product is so simple to install. My teenage son can do it. The replacement cartridges are nothing at all to change. Screw off the side clear parts- take out old cartridge and put in new. Make sure to match up red with red and blue with blue and that’s it. Run the water on hot for 3 minutes to activate and flush- good to go! The initial price of unit may seem steep- but it’s not when you see the results. The refills are fairly priced and worth it! I have to change mine more often due to the severity of the harsh chemicals added to my water in my local area. Still worth the money even when changing more often. My skin, hair and histamine responses all thank me haha.

Great filter. Wish it lasted longer
They work great just wish they lasted longer. Only last about a month or so and then the water pressure drops a noticeable amount

Very good, effective product.
This filter set is great and will last for a long time. You don’t need to replace the charcoal one until after all the white ones have been used, which is months later, depending on your water quality. My skin no longer itches with these filters. Don’t lose the O-rings or the water won’t flow.

Good but pricey
It works well. Installation is incredibly simple like other reviewers have also commented. The filters run out in about 4 months and need replacement and that’s when it gets a little pricey.I like the fact that it does its job well and is not too much of a hassle but I do think it’s an expensive option when you consider the filter replacement cost of every four months

They filter everything claimed…
I thought I had already rated these, but guess not!It is shocking how much they filter. I change them out every 60 days. Sounds expensive, right? Not really when you think about what they do.The largest organ we have is our skin. Most people don’t think about, maybe just don’t care or know, about their shower water and all the toxins that go into our system via our skin – while taking a shower or bath. I guess people believe and have faith about what their utility company says: it’s safe. Safe is a relative word. Somehow, I don’t believe the VP’s and up shower, drink and have their loved ones use the water without filtering it! So, why should we? Flat out, the filters work and do what they claim.I’ve read complaints that they drop water pressure etc. Well, they will a bit. Solution is to get a different shower head that maximize water pressure. And, it the filters didn’t drop water pressure a bit, then they aren’t working. But, don’t take my word for it. Order them, try them out and a few things you will notice right away, and another one within a week.First thing is how the water feels on your skin and hair. Second, there is absolutely no smell at all. Once you are used to a really good filter, you will smell chlorine instantly with unfiltered water. Third is that within a week, you will notice that you won’t have to clean your shower stall all the time. By the filters doing their job, there really is no residue in the shower or walls. Man, as a single guy, I really like that!
