PUR Water Filter Lights Meanings

PUR water filter lights come in green, yellow, and red. When the light is green, you are ensured that your water supply is contaminant-free and safe for drinking, as it indicates that the filter is working as expected.

After the filter has been in use for a long period of time, you may notice the light turn to yellow, which is a notification that the filter’s life is nearing its end.

The life span of PUR filters varies among the different types of filters, with faucet filters usually filtering up to 100 gallons for up to 3 months and pitcher and dispenser filters usually filtering up to 40 gallons for up to 1 to 2 months.

But we don’t always get to keep track of the time from when we first used our filter. So filter lights are really helpful because they allow you to determine when to change your filter more accurately.

When the light turns red, it means the filter has reached its limit. By then, the filter has already been filled with contaminants and can no longer filter your water. This would require immediate filter replacement.
