This may occur if bubbles or air pockets have become trapped in your filter. To help remedy this, we recommend removing the filter from your pitcher, then holding the filter upside down at a slight angle and shaking it for 5-6 seconds before returning it to the upright position. You should hear the carbon particles inside moving. This should compact the contents of the filter and eliminate any air pockets trapped within, which can prohibit water flow. This should restore full performance to your filter.
Depending on the hardness of your water, pitcher filters should be changed every 40 gallons of water or about every 2 months, whichever comes first. If your unit features an LED indicator light, it will turn from green to yellow or red when the filter needs to be replaced. The light will flash only when in use. Green indicates the filter is working. Yellow indicates the filter will need to be replaced soon, while a red light means the filter needs to be replaced immediately.
