Household Modules

Aqua Clara International (ACI) has designed a simple, cost effective, household water filter which can provide up to 300 liters of 99.999% (Log6) bacteria-free water to families living in rural and urban settings who have access to municipal or well water. This ACI Household Filter is constructed using hollow membrane technology and local materials where available.  It can be combined with sand if necessary, and is the 3rd and smallest model ACI now offers, the others designed for use in larger applications.

Technical Information

  • 2 0.1micron Hollow Membrane units installed into a 1/14 inch pvc housing
  • 1 pvc ¾ inch tap with rubber seal
  • 1 75 micron pre-filter screen
  • 1 bucket, 5 gallons or more.
  • 1 large back flushing syringe

This filter can produce up to 99.999% bacteria free water at 1 liter per minute when full, thus producing 300+ liters of water in a day.  The filter will last up to 10 years if properly maintained and back flushed regularly.

For the past 12 years, various members of the Fifth Reformed Church of Grand Rapids, Michigan have volunteered with for an organization called International Medical Assistance (IMA). IMA coordinates volunteers from all over the United States and Mexico to provide medical care to the impoverished Mayans in the areas surrounding Valladolid, Mexico. They have built a surgical center and offer free consults and surgeries, among other initiatives.

Four years ago the church started a water project with the support of ACI. The most recent trip was a team from Northern Nevada that was introduced to Aqua Clara by Fifth Reformed Church. Altogether they brought 60 filters to four villages in late June of 2014. The villages that received the filters were Tixcacalcupul (25 units), Tamuy (10 units),San Francisco Tinum (6 units), and Dzitnup (18 units).
