Re: What are your thoughts on the Gravidyne

I sure like the idea of drinking water from stainless rather than plastic. The Gravidyne touts each filter can handle 13,000 gallons of water to purify (that's 39,000 gallons for the 3 filters) and/or change every 6 months. Big Berkey claims 3,000 gallons for each (that's 12,000 gallons for 4 filters). Both seem to equivalent on what they filter. The price of filters are about the same. What is your take on the Gravidyne?

"Gravidyne filter" - Review of Katadyn TRK Drip Filter with Gravidyn Element

We have a cistern for our house which meant we cold not drink draw water from the faucet to drink. We were buying between 8-11 gallons of drinking water per week at a cost of .70-.80 cents per gallon. We searched for alternatives and choose to filter the water from the cistern with the Gravidyne. With a filter life of 39,000 gallons and the initial cost of the filter, we figure the cost per gallon is less than 1 cent and the water taste great.How can you beat that. We are very happy, just fill and walk away. I highly recommend. I can't imagine its value in a emergency.
