When do I Change the Water Filter?

Question: When do I Change the Water Filter?

When do I Change the Water Filter? And what affects filter life? Is filter life the same for any water filter?

Answer: When to replace your water filter will depend on a several factors. Water filters generally have an estimated life cycle usually measured in gallons of water, but this is only a guideline based on average water use, which is not always a good indicator, since water use varies per household.

What Can Affect the Life of Your Filter:

  • The overall condition of your water in terms of contaminants and how much must be filtered.
  • If you have hard water (heavy with minerals) which causes scale to build up and clog the filter.
  • If you use more water than the average household.
  • How well your water was previously treated or filtered.
When an active carbon filter becomes clogged or for some reason can no longer attract particles and contaminants, it becomes ineffective and useless. It's time to replace it.

Signals that the Filter Needs Changing:
  • You may detect an odor in the water.
  • Water takes on an unpleasant taste.
  • There's a gradual decrease in water pressure.
  • Filters with clear containers give a visual indication that the filter is dirty.
  • You have exceeded the manufacturer's water usage guidelines.
Replacing your water filter as needed ensures that your water filtration system is working effectively. You should always keep a back-up filter on hand, for convenient change-outs. Water filters are sold by brand and you can find the part or model number of your filter by referring to your water filtration system's manual or the manufacturer's web site.
