Voting rules: Choose the water filtration system you think is the most advanced!
This is a community-based ranking of the most advanced water filtration system. We do our best to provide fair voting, but it is not intended to be exhaustive. So if you notice something or system is missing, feel free to help improve the ranking!
A participant may cast an up or down vote for each system once every 24 hours. The rank of each system is then calculated from the weighted sum of all up and down votes.
