Make sure to change your PUR Water Filter if the filter indicator turns out red.

The earlier you replace the old filter, the better it is.

What Causes Early PUR Water Filters Replacement?

  • An extreme water hardness level causes early water filter replacement.
  • If your tap water contains excessive pollutants and contaminants, you need to change the water filter more often.
  • Sediment buildup from continuous and heavy regular use will result in faster water filter replacement.
  • Too much iron in the water causes the filter to work harder, leading to early change.
