Why can't I use my Shower Filter with a "low-flow" or "stop-flow" shower head?

Graeme Updated by Graeme

In order to get the correct pressure for proper filtration, the Shower Filter needs to flow at 1.6 gallons per minute (6 liters per minute). This means that shower heads that purposely restrict water flow will most likely result in sub-par water pressure, and as a result are not compatible with the Shower Filter.

How did we do?

How long does the Shower Filter last?

Can I install the Santevia Shower Filter backwards?
