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.

If you are using a new filter and find that your filter is taking longer than 35 minutes, an extra long soak and additional flush will help to speed it up. To do so, remove the filter from the reservoir and fill the pitcher to about 3/4 full with tap water. Place the filter upright in the water and the reservoir back on top of the pitcher to keep the filter submerged. Soak it overnight, about 8-10 hours. Then flush the filter, increasing the pressure slowly over the course of 2-3 minutes. That will limit the amount of water passing over the filter and increase the amount passing through it. Once you’re finished, reinstall the filter in the reservoir and you’re good to go.

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