Important Safety Instructions
The Hydraid® BioSand Water Filter is designed for daily use with water
that is contaminated with bacteria, parasites, and viruses. The filter
does not remove heavy metals. The Hydraid® BioSand Water Filter is
not approved by the U.S. Environmental Protection Agency for drinking
water in the United States. The filter is intended for intermittent usage
with periods of pause (1 to 4 hours) and if used continuously, should be
followed with chlorination. Post filtration chlorination is always recommended since cross contamination of stored water is a reality. Chlorine
should always be added to post-filtered water and never be added to
the water entering the Hydraid® as this would negatively impact the
biolayer. The biolayer is a living system and should not be left for longer
than two days without having water run through it.
It can take up to 14 days for the biolayer to form after the filter is installed, and during this period, post filtration chlorination is absolutely
necessary to address bacteria and viruses. The filter media (sand)
accounts for essentially all parasite removal immediately. Within 14 days
of installation, the filter will achieve optimal efficiency and effectiveness.

Assembly (see visuals)
1. Remove the transparent hose from the flat
end of the plumbing tube.
2. Screw the fitting of the transparent hose into
the side of the PVC standpipe Tee.
3. Insert the flat end of the standpipe into the
opening at the top of the filter below the rim.
4. Turn the filter upside down. Firmly push the
standpipe down until it is in line with the PVC
union at the bottom of the filter.
5. Firmly push the elbow end of the standpipe
into the PVC union at the bottom of the filter.
No PVC glue is needed.
6. Turn the filter upright and continue with the
installation.
Installation
Filter Location Selection
1. Involve household members in selecting
the filter location for acceptance,
convenience, and permanence.
2. Choose a safe, clean, permanent area
indoors to place the filter. Once installed,
the filter should not be moved.
3. Make sure the location is a protected
area, preferably in a corner or against a stable wall in the kitchen
where the filter is convenient, yet not likely to be bumped or damaged.
4. Place the filter upright, and level with shims if necessary. Keep
away from direct sunlight, wind, rain, freezing temperatures, heat
sources, clutter, and animals.
Filter Placement
1. Position the filter carefully on a level and stable surface.
• On a hard dirt floor, you may need a hammer to break up the
surface to make it level.
• On a concrete floor, you may need to use wooden shims to
make it level.
4
• Consider constructing a concrete or wooden platform.
• Avoid placing on elevated surfaces to prevent tipping and to
make filling easy.
2. Level the filter with a contractor’s level. Check both front to back
and side to side.
3. Where possible, position standpipe assembly facing a wall with
the flexible Outlet Tube turned in a convenient direction.
Filter Installation
Note: You must ALWAYS add Gravel or Sand into standing water.
If necessary, replace the Diffuser Plate and add additional water to
the filter so that you are always pouring Gravel or Sand into standing
water.
1. Fill with about 4 gallons of water. Confirm there are no leaks.
2. Add Underdrain Gravel to a depth of about
7 cm (3125 ml or about 9.6 lbs). This is the
bag with a green label if purchased through
Triple Quest. Make sure this layer is level.
3. Add 5.7 cm of the smaller Filtration Gravel
(3350 ml or 9.9 to 10.6 lbs). This is the bag
with a yellow label if purchased through Triple
Quest. Make sure this layer is level. Both layers of gravel should
add up to a depth of about 12.7 cm together.
4. Rapidly in a sweeping motion, fill the Filter Body with 34 liters (49.9
kilos or 110 lbs) of Sand (sand from Triple
Quest is marked with a red label). Make sure
the sand comes all the way up to the raised
textured line that is on the inside of the filter
body. It is important to do this as fast as possible to prevent sand stratification and the filter
plugging. It is helpful if two people are available to pour the sand simultaneously. Make sure this layer is level.
Save any extra sand for maintenance later.
5. Place the Diffuser Plate and the Filter Lid
on the Filter Body. Identify the filter with
location, date, serial number, and name of
installer on an Installation Survey form.

6. Pour one or more buckets of water through
the Diffuser Plate until the water flowing from
the transparent hose runs clear
(usually less than 20 liters or 5 gallons).
Checking Flow Rate
1. Flow Rate: To ensure the flow rate does not
exceed .8 liters per minute, replace the Diffuser Plate and fill the
filter to the rim with water. Put a 1-liter container at the end of the
transparent hose to collect the water. Use a watch with a second
hand to count out 60 seconds and collect the water for that
entire time. At the end of 60 seconds, you should have collected
between .4 and .8 liters (400-800 ml). If you collect between .4
and .8 liters, your filter is working properly. If you collect more
than .9 liters, contact Triple Quest at 616.254.4114.
2. Depth Measure: When the filter is at rest (i.e. no water is being
filtered), remove the Diffuser Plate and measure the depth of the
standing water. There should be almost 5 cm (2 inches) of water
above the Filtration Sand.
Clean Water Storage Container
A container of approximately 20 liters (5 gal.) size is ideal. Avoid larger
containers that cause weight-related handling issues and safe storage
considerations. Note: Water weighs about 1 kg per liter (8 pounds per
gallon). A suitable storage container should meet the following criteria:
1. Be easy to clean
2. Be used exclusively for filtered water
3. Have a secure cover with a small opening to fill with post-filtered,
clean water (optional)
4. Have a handle for carrying convenience (optional)
5. Have a spigot or faucet for sanitation and convenience (optional)
Refrigerate or chlorinate post-filtered water if possible. Both help
protect post-filtered water from recontamination.
Note: A clean storage container is part of an overall sanitation
and hygiene program. For more information, see www.hydraid.org.
Using The Hydraid® Biosand Water Filter
Your filter is a living system. The biological layer must be fed with at
least 15 liters (3 gal.) of water every other day to insure it remains alive
6
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 properly. 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 reduction. 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.
