A Silicon Valley startup called Liquidity today announced that its “Naked Filter” water bottle is now available for pre-order. The bottle is a simple and cheap way to remove microorganisms from water and thus making clean water available to everybody. Liquidity says that the Naked Filter is the result of more than 15 years of material science research and development which created “a new solution for water filtration.”

The startup claims that Naked Filter will remove 99.9999% of disease-causing bacteria and protozoan cysts as long as the filter lasts. When the filter’s life is up no more water passes through it. This tells the user that it’s time to swap it with a new one.

There’s no sophisticated technology in the bottle itself. Just pour water into the bottle and screw on the cap. When you drink water out of the bottle it will pass through the filter and automatically be purified.

Liquidity is running the pre-order campaign on Kickstarter and it’s looking to raise $40,000. Already it has raised some $12,000 with 29 days still to go. Pledging $10 now will give backers one bottle and one filter.

Once this tier runs out the basic model will be available for a $14 pledge. Backers can pledge up to $10,000 and every tier has different perks. Shipment is expected to begin in August 2015.
