The AQUA Logic Siphon Drinking Water Filter functioThe Siphon filter is a so-called Point of Use filter. This means that the water is treated where it is used. This minimizes the risk of contamination during the journey from source to user.
Emergency drinking water filter
This water filter is used worldwide in emergency and disaster situations where there is a lack of clean and safe drinking water. Disease caused by contaminated water is unfortunately the number 2 cause of death worldwide and even the number 1 cause of death among children up to 5 years old. Often more people die from the disaster after the disaster than from the disaster itself. With your purchase you support the work of the IBOTA Foundation and making this water filter available to those i
Aid and Relief
The Siphon filter is a simple and very compact drinking water filter that has been specially developed to give people who live in poor conditions access to clean and safe drinking water. For example, this filter is distributed by various aid agencies to families in disaster situations or underdeveloped areas.
Drinking water for the whole family
This little powerhouse can clean 10 liters per hour. It is super small and cheap to buy. This filter (if used correctly) can provide a family with clean and safe drinking water for a period of at least 1 year. Practice has shown that this can take up to several years, depending on the degree of contamination of the water source.
Backpackers
Are you on the road, through nature or abroad and do you doubt whether the tap water is drinkable? Even then this compact water filter is the solution.
Suitable Water Sources for Use with Our AQUA Logic Emergency Water Filters
- Rainwater: Easy to collect and directly filter.
- Surface Water: For example, from ditches, lakes, rivers, and streams.
Tip: For optimal results, we recommend pre-filtering surface water with a cloth, such as a tea towel, to remove large contaminants.
- Spring Water: Water from natural springs, if accessible.
- Snow and Ice: Melted snow or ice can be filtered.
Note: Do not use snow or ice that is contaminated with salt or has lost its clear white color.
- Groundwater: Water from shallow wells or boreholes.
Note: If the groundwater contains iron, it can be easily de-ironed by adding oxygen to the water. This can be done by pouring the water back and forth between two buckets. Allow the water to settle so that the iron particles accumulate at the bottom. The clear water on top can then be filtered with the AQUA Logic emergency water filter.
- Rain Puddles: Water collected in depressions after rainfall. Pre-filter large contaminants before filtering.
- Condensed Water: Water collected through condensation, such as with plastic sheets or collection systems.
Note: This filter is not suitable for purifying saltwater or heavily chemically contaminated water.
Filter Characteristics 4-in-1 CS-Ultra Filter Element with Sediment Filter Sleeve
1. Activated carbon cylinder with a pore size of 1 micron.
Activated carbon is an organic material that reduces substances affecting odour, colour and taste, as well heavy as metals, chlorine, pharmaceutical residues and other chemicals.
2. Nano Silver Impregnation
The activated carbon contains a small amount of nanosilver to support the hygiene of the filter element during use. The microbiological purification of the water is achieved by the ultrafiltration membrane.
3. Ultrafiltration membranes with a pore size of 0.01–0.03 micron
Ultrafiltration membrames providing effective filtration against:
- Pathogenic organisms: Bacterial reduction of >99.9999% (including Cholera, Shigella, Typhus, Klebsiella terrigena, Enterococci, Legionella, and E. coli)
- Cysts/Protozoa: (including Giardia and Cryptosporidium)
- Micro- and Nano-plastics: Removes particles as small as 0.03 microns (30 nanometers)
4. Sediment Filter Sleeve
The Sediment Filter Sleeve is very effective in filtering coarser contaminants in the water such as sand, mud and clay. The Filter Sleeve extends the life of the activated carbon and the ultrafiltration membranes, which will be less likely to clog.
All parts are BPA-Free. The filter works without the addition of chemicals and is made up of maintenance-free and corrosion-free parts.
Usage Options
A. Use with Siphon

1. Connect the hose on filter.
2. Place the supplied filter cover over the filter and pull the cord tight.
3. Completely submerge the filter in a bucket of water.
Tip: If necessary, place a weight in the cover.

4. Place the supplied syringe on the outlet hose.
5. Draw air in with the syringe (5.1) and push it out (5.2). Repeat until water starts to flow.
6. The filter is ready. The outlet hose can be closed by pressing the clip.
Note: Do not use the first approx. 5 liters of filtered water for consumption.
B. Use with Gravity

1. Insert the outlet with one sealing ring through the hole of a reservoir, place the second ring on the underside, and tighten the nut.
2. Place a second reservoir and fill the upper reservoir with the water you want to filter. The water will start to pass through the filter element after a few minutes.
Maintenance
A. Cleaning the Filter
Lightly scrub the surface of the filter using the integrated cleaning pad. Rinse the filter and ensure the outlet does not come into contact with contaminated water. Using the supplied syringe, gently push clean water back through the filter (backwash). Do not consume the first liter of filtered water.
B. Cleaning the Hose
Connect the outlet hose to the supplied syringe. Draw hot water through the hose by placing it in a container with boiling water. Let the hot water sit in the hose for 3 minutes. Then
gently pull and push the water back and forth several times.
Storage after Use
Wet Storage (1–4 weeks): Disassemble the filter element. Store it in a sealed container or bag, preferably in the refrigerator.
Dry Storage: Let the filter air-dry in a clean area. Drying near a heat source, such as a radiator or in sunlight, is recommended — but avoid direct contact between the heat source and the plastic parts, as this may cause damage.
Note: When the filter is put back into use, it may take some time before the water flows through properly. As a precaution, do not use the first liter of filtered water for consumption.
Shelf life and Life Span
Unused, the filter has an almost unlimited shelf life (store in a cool, dry and dark place). The adviced service life is 1 year; the actual lifespan of the filter element may vary depending on the degree of contamination in the source water. As long as water continues to flow through the filter, it is safe to drink, even if the flow rate decreases.
Groundwater and De-Ironing
Groundwater may contain iron, which can cause a metallic taste and discoloration. You can easily remove iron from the water before filtering it with the AQUA Logic emergency water filter. Follow these steps:
- Add Oxygen: Pour the groundwater back and forth between two buckets several times. This allows the water to absorb oxygen, oxidizing the iron.
- Let it Settle: Allow the water to sit for several hours so the oxidized iron particles settle at the bottom.
- Separate the Water: Carefully scoop or pour the clear water from the top into another bucket, leaving the iron particles at the bottom.
- Filter: The clear water is now ready to be filtered with the AQUA Logic emergency water filter.
This simple method works well for water with low to moderate iron content. For water with high iron levels, additional techniques or tools may be necessary.
Disclaimer
This water filter is designed to reduce a wide range of contaminants to levels generally considered safe for daily use. However, it may not be effective against water heavily contaminated with industrial chemicals or hazardous substances. Although water quality is significantly improved, the filter is not intended for specialized or medical use. Individuals with weakened immune systems or specific health concerns are advised to take extra precautions and consult a professional if necessary.
