HOW OFTEN SHOULD I CLEAN MY WATER FILTER?

The basic rule of thumb for cleaning or changing a water filter is every 40 gallons or two months.

However, how often you change your filter also depends on other factors like:

Water consumption of household

Brand/unit of filtration system

Amount of elements that need filtering

Hardness of water 

You should change your filter every 2-6 weeks if you have a large number of people in your house, you use the filtered water frequently, you have hard water, or you have medium to heavy sediments.

Most residential water filters will have a cling calendar or electronic indicator to help determine when it’s time to change or clean your filter.

You use the cling calendar to see when you last changed your filter, and it will show you when you should next change. You have to remember to look at the calendar, though.

The electronic indicator is able to measure the effectiveness of the filter. The indicator will blink or illuminate when the filter needs to be changed. This takes the guesswork out of changing your filter.

It’s easy to mindlessly pour water and ignore any indicators to change your filter, though. Thus, you might also want to set a reminder on your phone or calendar. After you change your filter, schedule another change in one or two months.
