Weddell Duo FAQs

What makes Weddell Duo different from other shower filters?

The Weddell Duo is unique in several key ways:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. Easy Installation: Installation is tool-free and the Weddell Duo is compatible with a variety of shower heads, including rain, fixed, and handheld models.

How often do I need to replace the filter cartridges?

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.

What contaminants does Weddell Duo remove?

Weddell Duo is designed to significantly reduce a wide range of contaminants including chlorine, PFAS, and particulates. This helps to improve the quality of your shower water for healthier skin and hair.

What are the reduction percentages for the contaminants that Weddell Duo removes?

Weddell Duo Shower Filter is NSF certified and has been rigorously tested and verified by an accredited third party lab to ensure high performance. Below are the specific contaminants it removes:

Free Available Chlorine: 99%

PFAS: 99%

Particulates: 99%

While Weddell Duo reduces other contaminants, we only publish reduction claims for those we have tested using established industry standards to prioritize transparency and reliability. Please see our testing data here for the most updated information.

Can I install the Weddell Duo Shower Filter myself?

Yes, the Weddell Duo Shower Filter is designed for easy, tool-free installation. It fits most standard showers and can be installed in minutes without the need for professional help.

For additional help, please check out our installation guide.

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.

Solution for post-Helene water issues

I live in Asheville, North Carolina and we do not yet have potable water post-Helene. Although so much work is being done to fix our water, we are still showering in water that is extremely turbid (last testing showed turbidity of 19) and heavily chlorinated. The turbidity causes the water to look light brown and the chemicals used to treat the water make my eyes burn and my skin really dry. I bought this filter in hopes that my daughter and I would be able to take showers that were more comfortable. I've showered twice since it's been installed and my eyes did not burn, the water does not smell like the strongest pool water you can imagine and my skin wasn't dry and cracking when I got out. I cannot even put into words how nice it's been to take a normal-ish shower and how impressed I am with this filter. I am sure I will have to replace the filters quite a bit until our water situation improves, but it's definitely worth it! Oh, and installation is super easy! Highly recommend this product!

So far so good

This feels sturdy and after my first shower my skin has felt softer and this didn’t leak either I was pleasantly surprised.
