FREQUENTLY ASKED QUESTIONS - WATER FILTERS
Q: How do the filters work?
By simply elevating the bucket with the attached filter, let gravity do all the work. The water will pass down through the filter, clean the water and pour directly into a clean glass or clean container.
Q: What do the filters remove?
The filters are certified for ABSOLUTE microns making it impossible for harmful bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through.
Q: Are the filters and purifiers tested and approved?
The filters and purifiers have been tested by independent and qualified research laboratories according to EPA standards for water filter and purifiers.
Q:How long does the filter/purifier last?
Since the filters and purifiers can continuously be backwashed and re-used they have an extremely long life. The filter/purifier membrane may never need to be replaced, however when the flow rate slows or the filter clogs, simply backwash the unit with the provided backwashing device to clear out the pores.
Q: How much water can be filtered/purified per day?
The flow rates of the filters and purifiers are determined by a combination of four variables:
- Head pressure (The distance from the top of the water to the filter)
- Altitude (The higher the altitude, the slower the flow rate)
- How clean the filter is
- The filter itself (there are slight variations between filters)
Q: How often do you have to clean or backwash the filter?
The frequency of cleaning depends on how dirty the water is. With relatively clear water, backwashing may only be necessary every 1,000 gallons whereas with extremely turbid or muddy water, backwashing may be required every 10 gallons. Nevertheless, backwashing is an extremely simple process and takes only a minute.
Q: Will the filter/purifier remove chemicals, pesticides, heavy metals like arsenic or salts?
Q: Where can I learn more about the filter?
We pride ourselves on taking the most solid and trusted water filter created, deep within the poorest of areas in rural Guatemala.
