and able to consume and reduce bacteria. However, the biological
layer cannot effectively consume and reduce the maximum amount of
bacteria if operated continuously. If the filter is to be used continuously
without pause periods, the filtered water must be properly chlorinated to
address bacteria and viruses. Never add chlorine/bleach to water that
is inside the filter. Nor should you put chlorinated water into the filter.
Only add chlorine to water after it has gone through the filter.
Usage Of The Filter
1. Pour at least 15 liters (3 gal.) of water through the filter at least
every other day. After pouring water into the filter, wait a minimum
of 1-4 hours (but no more than 48 hours) before adding more.
This pause period is necessary to allow the filter to work prop-
erly. The filter will reduce parasites and helminths immediately,
however, to dramatically improve water quality and positively
impact health you must wait 14 days for the biological layer to
fully develop.
* The biological layer accounts for most of the filter’s bacteria
reduction capabilities and takes up to 14 days to fully develop.
This thin, invisible film of living organisms naturally grows on
and within the top surface of the sand within the paused water
reservoir, where it consumes bacteria and viruses. During the
14-day period, the filter’s ability to remove bacteria in the water
steadily increases proportional to the biological layer development.
The Filter Media (sand) accounts for essentially all parasite reduc-
tion. Within 14 days of installation, the filter will achieve optimal
efficiency and effectiveness. Scientific health impact studies
have shown that the Hydraid
®
BioSand Water Filter dramatically
improves water quality and reduces the incidence of diarrhea by
47% without additional interventions such as chlorination, hand
washing, or other hygiene and sanitation measures.
2. Chlorination of post-filtered water to reduce bacteria and viruses
is strongly recommended during the first 14 days. A dropper
bottle can be used, and a reasonable effort should be made
to continue routine chlorination after the startup period. This
protects stored water from naturally occurring recontamination
associated with water storage. To chlorinate post-filtered water:
• Fill dropper bottle with 5.25% chlorine (household bleach).
Note: Bleach is not available in all countries, and solution
strengths vary.
WARNING: Keep chlorine away from children.
