Why is my MINA Pitcher filtering slowly or not filtering?

Your MINA Filter may be filtering slowly or may not be allowing water through to the lower tank for two reasons:

Reason 1

The MINA Pitcher holds 9 cups of water. Once this amount is reached, any more water that is added to the upper tank will not be able to filter through to the lower tank. As a consequence, it will remain unfiltered in the upper tank until you pour some water out of the pitcher.

Reason 2

If your MINA Pitcher is taking a long time to filter, you may have air bubbles in your filter which prevent water from passing through.

Many faucets introduce air into the stream of water as the water leaves the tap. Occasionally this allows air bubbles to become trapped within the filter, slowing down or blocking the flow of water from the upper to the lower tank. A gentle tap of the pitcher on the counter will "burp" the filter, release the air bubble, and allow water to filter through.
