Performance You Can Verify
The Weddell Duo is unique in several key ways:
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.
Weddell Duo is designed to significantly reduce a wide range of contaminants including chlorine, PFAS, particulates, 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:
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.
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.
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.
