Frequently Asked Questions
Why do the filters have to be primed?

Priming the BOROUX Filters is necessary for proper function. This procedure is what activates the carbon and breaks the surface tension, so that the contaminants get trapped, and the water gets through. The filter is made of very dense material and priming forces water through the material so that it’s entirely saturated. This is a crucial initial step for using the filters. 

The media that the BOROUX Filter is made of has a micropore structure. These micropores are miniscule which can create tiny pockets of air. Along with the high surface tension of the filter material, without being primed first, water cannot pass through those air bubbles. Priming uses water pressure to force water through those micropores so that when water is passing through only using gravity, it can. If the filters are not primed, the flow can be extremely slow, if not completely nonexistent.
What if I don’t see beads of water on my filter when priming?

Each filter is unique, some filters shows lots of water beads, others do not. As long as the filter is fully saturated, they are primed. Running water through the filter for 1-2 minutes fully saturates the filter.

How do I know if the filters are primed?

The buoyancy test can determine if the filters are fully primed.

  1. Fill the lower chamber or another large container with water
  2. Place the filters in this container with the stems up.
  3. If it sinks (or slightly floats), the filter is primed and ready to install in your system!
  4. If the filter bobs back up quickly, prime again.
How many filters can I prime per battery charge?

On a full charge, you can prime a minimum of 10 filters before needing to recharge the primer.
It takes approximately 90 seconds to fully prime one filter.
Is the Automatic Filter Primer compatible with my Berkey filters?

Yes. The Automatic Filter Primer is compatible with Black Berkey Filters as well as BOROUX Foundation and Proactive Fluoride Filters (adapter included with fluoride filters).
What do the different light indicators on the Automatic Filter Primer mean?

The light on your Automatic Filter Primer helps you quickly understand the current battery status. Here's what each light color and behavior means:

  • Solid Green: Fully charged and ready to use
  • Blinking Green: Currently charging
  • Blinking Red: Battery level is below 25% — charge soon
  • Solid Red / No Light / Blank: Battery is critically low or depleted — needs to be charged immediately

If you're unsure whether the pump is working correctly, we recommend fully charging it and checking the light again.
