How affordable is it to own a Berkey filter?

You can easily calculate how often you have to change the Black Berkey filters.

Here is the Preferred Method

- Take the number of Black Berkey filtering elements in your system and multiply it by 3,000. This number will be the (Total Life) in gallons.
- Estimate the average amount of water you filter through your Berkey per day. This number will be the (Total Use) in gallons.
- Then simply divide the (Total Life) by the (Total Use). This number represents how many days your filter will effectively treat your water before needing to replace them.
- As a reminder, with a permanent marker write the date that you calculated the need for Berkey replacement filters on the bottom of your unit..

Example: If you have a** 2 filter** Big Berkey and your used 4 gallons of water per day. You would multiply 2 (#of filters) by 3000 = 6000 (Total Life), then divide 6000 by 4 (total use) = 1500 days the filters will last, That’s a little over **4 years!**

**Lets calculate!**

**4 Gallon bottled water** = $4 (if you get the cheapest kind)

**4 Gallon **bottled water per day for **4 years, **you’ll spend** $5840 **

**The Berkey Travel Filter filters 6000 Gallon of water for 0.038 cents per Gallon.**

4 Gallon Berkey filtered water per day = $0.153

4 Gallon Berkey filtered water for 365 days = $56** X 4 years = $224**

**Savings $5616** in 4 years by a 4 Gallon water consumption per day
