Why
Water?
Nearly 700 million people lack even basic drinking water services. Clean water at home can change daily life for a family.
Global Water Crisis
Unsafe drinking water puts families’ health at risk. Children are especially vulnerable to illnesses that cause diarrhea and dehydration.
Nearly700 millionPeople lacked even basic drinking water services in 2024.1
1.4 millionDeaths each year could be prevented with safe water, sanitation, and hygiene.2
395,000Of those preventable deaths are among children under five.2

A practical solution for the home
We use Sawyer household filters that work with gravity. Local leaders teach families how to use, clean, and care for them.
- No electricity neededWater flows from the bucket through the filter using gravity.
- Easy to maintainFamilies learn to backwash the filter with clean water to help maintain its flow.
- Built for long-term useWith proper use and care, filters can remain in service for years.

| Filter | Sawyer PointOne, hollow fiber membrane, 0.1 micron absolute |
|---|---|
| Removes | 99.9999% of bacteria, protozoa, cysts and microplastics (manufacturer rating) |
| Does not remove | Viruses (not rated; it’s a filter, not a purifier), chemicals or heavy metals |
| Rated life | Up to 100,000 gallons (manufacturer rating) |
| Maintenance | Backwash with clean water using the included device; Sawyer says this restores up to 98% of the original flow rate |
| Quality control | Sawyer tests every filter three times during manufacturing |
| In the kit | Filter, hose, adapters, backwashing device and hanger; attaches to a food-grade bucket (never one that held chemicals) |
| Power | None; gravity-fed |

Why this filter works
Why household filters?
In many communities we partner with, families have a water source, but the water needs treatment before drinking. Household filters offer a practical way to address that challenge at home, alongside training and follow-up.
What clean water changes
Health
Safer drinking water helps protect families from waterborne illness.
School
Fewer days sick can mean more days in class.
Household expenses
Clean water at home can reduce spending on purchased water and treatment for water-related illness.
FIBER STRENGTH - KNOWN AS HOOP STRENGTH
What it means and why it matters
WHAT IT MEANS:
Thicker fiber walls and smaller inner diameter of the fibers make fibers ~75% stronger than fibers of other typical hollow fiber membranes.
WHY IT’S IMPORTANT:
Stronger fibers allow for aggressive backwashing and shock resistance. Meaning each filter can be continually backwashed forcefully restoring up to 98% of the original flow rate.

ABSOLUTE MICRONS
What it means and why it matters
WHAT IT MEANS:
- No pore is larger than 0.1 micron in the filters.
- Sawyer WILL not use average or nominal pore size ratings.
WHY IT’S IMPORTANT:
- Without absolute pore size, larger holes are present which could allow bacteria, protozoa, cysts, or viruses to pass.
- No harmful bacteria, protozoa, or cysts can pass through Sawyer filters.
- All Sawyer filters will remove 100% of microplastics from the water.
100% INDIVIDUALLY TESTED 3 TIMES
What it means and why it matters
WHAT IT MEANS:
Every filter is performance tested three different times during the manufacturing process for your protection.
WHY IT’S IMPORTANT:
To ensure every Sawyer filter is 0.1 absolute micron and that no harmful pathogens can pass through the filter.
Every filter is 3X tested. Sawyer does NOT batch test or statistically test for failure. Testing occurs after the fiber element construction and twice after casing assembly to ensure no harmful pathogens leak through the sealed case or internal o-rings.
PROTECTED FIBERS
What it means and why it matters
WHAT IT MEANS:
Our hollow fiber membranes are fully encased and sealed to keep them protected.
WHY IT’S IMPORTANT:
When fibers are not enclosed, physical damage of exposed fibers could allow harmful pathogens to pass through.

How clean water reaches each family
Local leaders know their communities best. ATTA provides filters, training, and support so they can lead distribution and follow-up.
They identify families.Local leaders identify families who need clean water and distribute filters in their communities.
They train families.Leaders teach families how to use, clean, and maintain their filters.
They follow up.Leaders check in with families, answer questions, and report back on filter use and changes families describe.
