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!
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
