Weddell Duo FAQs
What makes Weddell Duo different from other shower filters?
What makes Weddell Duo different from other shower filters?
The Weddell Duo is unique in several key ways:
- Certified & Verified Performance: It’s the only shower filter certified by NSF to reduce Free Available Chlorine, while also maintaining verified performance in reducing PFAS and particulates, and other contaminants. Most other filters don’t have these certifications and can't guarantee the same level of protection.
- Clinically Tested & Dermatologist Approved: Weddell Duo has been clinically tested to improve skin hydration and scalp health, and is dermatologist approved, making it an excellent choice for those with sensitive skin or scalp concerns.
- Clear Dual Cartridges for Easy Monitoring: The Weddell Duo has clear dual cartridges, allowing you to see the condition of your filters. The right sediment filter shows discoloration over time, signaling when it needs to be replaced.
- Long-Lasting Filters: Weddell Duo’s filters have a life cycle of up to 8,000 gallons, offering longer-lasting protection compared to many other filters on the market.
- Easy Installation: Installation is tool-free and the Weddell Duo is compatible with a variety of shower heads, including rain, fixed, and handheld models.

Will installing Weddell Duo affect water pressure?
Will installing Weddell Duo affect water pressure?
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.
Customer Reviews
Dear Friends, so far this water seems good. The flow of water through it is strong. I've had so many filters that after a few months have a significant reduction in water pressure coming through. It's too soon to say with this one, so we'll see how long it goes before it gets slow.
Thank you so much for your thoughtful review and for sharing a photo of your filters in action! We’re glad to hear that you’re getting strong water flow and are off to a great start with your Weddell Duo. Our filters are designed for both high performance and longevity, but if you notice any change in pressure down the line, don’t hesitate to reach out — we’re always here to help and offer replacement guidance if needed. Appreciate you giving us a try and keeping an eye on how it performs long-term!
What would I do without this filter? Love the sleek and simple profile, as well as the fact that the clear cartridges make it easy to see when to replace. I chose it for its ability to filter PFAS and I’m yet to be disappointed!
