We here at Lakota Scientific sell very good water filters. 

We know this because we have customers that have continued to refer our product to their friends for over twenty years.

The cost to own one of our water filters is $5.42 per month or $1.25 per week. This is the total cost over a ten year period including all filter changes.  There are no other costs because the filter is unconditionally guaranteed for your lifetime...if it fails, breaks or wears out, we replace it at no cost to you.
