We want to make sure you know how to determine how often you should change your filter. We get the question all the time, "How do I know when to change my filter?"

Here are 2 tips to help you calculate how often to change your filter.

Remember, these are all based on our Independent Lab Test Results, personal experiences using our own products, and recommendations based on average water quality. Because water quality varies significantly place to place we always recommend changing your filter before your notice any specific change to your water passing through your filter.

As mama always said, "Better safe than sorry!"

We never recommend a pitcher filter is used longer than 6 months as once a filter has been exposed to water it can begin to oxidize and over time will no longer remove the contaminants at a level it once did.

Tip #1: How many people are using the pitcher and what are they using it for?

One of the easy ways of calculating how often you change your filter is just by the amount of people using the filter. We try to remind you that though you might only have one or two people using the water that you should probably calculate in what else you use your water for as well (pets, plants, cooking, coffee, tea, etc.)

For a family (or high water consumption) we recommend changing your filter every 2-3 months

For a couple (or average water consumption) we recommend changing your filter every 3-4 months

For a single user (or low water consumption) we recommend changing your filter every 4-6 months


Tip #2: Do a simple math calculation to find out

Another way to determine the frequency that your should be changing your filters is to determine how often, on average, you fill your pitcher daily. Since our pitchers can filter 100 gallons of water, and the pitcher reservoir holds roughly 1/2 gallon, you should get about 200 fills of filtered water out of each pitcher. Here is the simple math equation to determine the amount of days between each filter change:

200 / # of Pitcher Fills per Day = Days Between Filter Changes

For example, I use my pitcher for 2 people, to cook, and to give to my dog every morning and night. I end up filling my pitcher about 2 times per day. So using the calculation above:

200 / 2 (times filled per day) = 100 Days

I should be changing my filter every 3 - 3.5 months or so.
