Doulton SS-4 Gravity Fed Water Filter

Best Use:

A Gravity water filter is the preferred choice for filtering your drinking water when a pressurized water system is unavailable. The portability and the fact that they don't require electricity to operate make them ideal for campers, travel, missionaries, emergency and disaster situations.

• The Doulton SS-4 comes with 4- 7" Super Sterasyl water filter Cartridges
• This gravity-fed water purification system can produce up to 24 gallons of water per day with all 4 super sterasyl ceramic cartridges installed. (If you don't require 24 gallons of water per day check out the Doulton SS-2, or remove 2 of the super sterasyl ceramic cartridges and fill empty holes with rubber plugs provided.)
• The housing of the water filter is constructed of high quality stainless steel
• This gravity fed unit is the best for portability. The upper chamber nests in the lower chamber for transport.
• Manually pour unfiltered water in upper chamber, and gravity will feed the water through the filters, then draw filtered water from lower chamber.
• 4 installed cartridges produce up to 1 gallon per hour.
• Lower chamber stores 2 1/2 gallons of filtered water
• 19.5"tall and 8.5" diameter - 5 1/2 pounds empty weight.
