  • 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.

Welcome to step zero of your self-care routine

Start your skincare routine off the right way

  • Tap water contains various contaminants that can irritate your skin, such as chlorine, microplastics, lead particles, and rust.
  • Chlorinated water robs your skin of its natural oils, leading to dryness, itching, redness, flaking, eczema & psoriasis flare-ups, acne, discoloration, and premature aging.

Say goodbye to lackluster hair and an itchy scalp

  • Unfiltered water can weaken hair, causing dryness, dullness, color breakdown, and reducing the effectiveness of your favorite haircare products.
  • Indulge your hair and scalp in the ultimate pampering experience with our patent-pending technology!

99.3% "forever chemicals" PFAS reduction

  • When you step into your shower, PFAS can be absorbed through your skin and inhaled as vapor, potentially increasing your risk of cancer (International Agency for Research on Cancer, 2017).
  • Weddell Duo was tested by IAPMO Lab to NSF/ANSI Standard 53 PFAS Reduction at 2.8 GPM in 2023.

Q&A

What should I do if my shower head is leaking or the pressure has decreased?

1) Please make sure that both O-rings are secured, 1 at the top and 1 at the bottom of the shower filter.

2) Please be sure to ONLY use 2 rounds of Teflon tape, too much tape can cause bulkiness and lead to a poor seal.

How often do I need to replace Weddell Duo's filters?

You should change your filters if any of the following occurs: 1) 5-6 months has passed, 2) you notice decreased water pressure and/or filter discoloration, or 3) when the rated capacity of the filter cartridge has been reached. The frequency of replacement depends on your water usage and the quality of your water supply. Regular replacement ensures that your shower water remains clean and safe.

Does Weddell Duo affect the water pressure in my shower?

Weddell Duo is designed to have minimal impact on water pressure. Since our maximum Gallons Per Minute (GPM) rate is 2.8 GPM, which is much higher than typical shower heads (2.5 GPM or less), your overall water pressure will be determined not by Weddell Duo, but by your shower head. However, as Weddell Duo reaches its full capacity, the accumulation of filtered impurities may slow down the water pressure. This is an indication that it's time to replace the filter cartridges to ensure optimal performance and maintain water pressure.

Does Weddell Duo work as a water softener?

Weddell Duo is not designed to lower the Total Dissolved Solids (TDS) in your water supply, so we do not recommend using it as your primary water softener. However, due to its exceptional filtration precision, it effectively reduces a wide range of impurities from your water, including limescale.

Small chewer dog friendly...2 in package..Funx2
Shiba pup LOVES these. We play fetch in the back yard with one and the other is to gnaw on rather than my couch inside!! He is a super super duper chewer and really enjoying his new teeth so much that he's gnawed past the brown of the stick to white plastic so I had to take 1 away. It's a smaller stick 6-8 inches so I do worry about him walking or running while playing fetch and falling (new feet too!!) and hurt his mouth or throat. I will definitely be replacing it at least 1x while he's small but I wouldn't recommend this item to a big dog with big teeth.

The best small dog chew stick ever
I've bought these several times and given them out to friends. These last a lot longer than the rawhide chews. Our poodles love them; over the past year, they are the go-to toy. My daughter and son-in-law's Dalmatian, who went through a moose antler in two days, still has one of these in decent shape after two months.

Great item for aggressive chewer
My dog is an aggressive chewer. He loves these! I had hoped it would stop him from chewing sticks and branches but it didn’t!

A bit smaller than expected
Dogs loved them but felt they were a bit smaller than expected. I had to take it away as I was afraid the dogs might choke / try to swallow.
