Installation FAQs

Can Weddell Duo be used with any type of shower head?

Yes, as long as it can fit into your shower water outlet pipe.

Will installing Weddell Duo affect water pressure?

Since our maximum Gallons Per Minute (GPM), 2.8 GPM, 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, by the time Weddell Duo’s full capacity is reached, it is natural for the filtered impurities in our filter to slow your water pressure, which would be an indication for you to replace the filter cartridges.

Do I need any special tools for installation?

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.

Replacement FAQs

How often do I need to replace Weddell Duo filters?

Our filter cartridges can last from 3 to 6 months.

However, replacement depends on three factors: (1) how long you shower, (2) how often you (and the people you live with) shower with Weddell Duo, and (3) how clean your running water is.

How do I know if I need to replace my Weddell Duo filters?

You will need to replace your filters if any of the following apply,

  • You’ve used Weddell Duo for over 5-6 months
  • Your shower water pressure has significantly decreased
  • Or filter #1, on the right of Duo, shows signs of discoloration
