Weddell Duo is designed to significantly reduce a wide range of contaminants including chlorine, PFAS, microplastics, heavy metals, and other sediments. This helps to improve the quality of your shower water for healthier skin and hair.
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:
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.
You can find documentation on NSF's website here.
Weddell Duo was verified to reduce PFAS and microplastics at IAMPO Lab in 2023. Backed by more than 80 years of IAPMO experience, IAPMO R&T Lab is a trusted name for independent testing, research, and technical services in the plumbing and mechanical industries. However, at this time, IAMPO does not offer certifications specifically for PFAS and microplastics reduction in shower filters. Instead, please take a look at our lab test reports here.
No. Weddell Duo is not designed to be used as a drinking water filter.
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.
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.

Nope, installing Weddell Duo is tool-free!
However, depending on how old your shower arm is, you may need a wrench to remove your existing shower head.
Yes, Weddell Duo is designed to be compatible with most standard shower heads—as long as it can fit into your shower arm or water outlet pipe. Whether you have a fixed, handheld, or rainfall shower head, the Weddell Duo can be easily installed to provide clean, filtered water for your 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.
Maintaining your Weddell Duo Shower Filter is simple. Regularly check the filter cartridge for any buildup of sediments and replace it every 3 to 6 months. For the housing, a gentle wipe with a damp cloth is sufficient to keep it clean. Avoid using harsh chemicals or abrasive cleaners to ensure the longevity of the filter.
