My filter is slow. How long should it take for water to pass through?

A properly working filter can take anywhere from 5 to 35 minutes to pass a full top reservoir of water.

The filter has a firm outer layer of filtration media that is densely packed. If you are using a new filter and find that it is taking longer than 35 minutes, it may require additional priming to allow water to pass through that outer layer of filtration media.

We have recently released a new priming tool that makes this step easy and consistent. This adapter, our flushing bag, gives a consistent amount of water pressure every time to pass through the densely packed filtration media.

To use the Flushing Bag, you can view the instructions and additional helpful information here.

If your filter was previously filtering within 5 to 35 minutes and has recently slowed down, please contact our team at
