The AQUA Logic Tab - C-Ultra has been developed to provide safe drinking water for household use, in situations where the regular drinking water supply cannot be trusted. It is a drinking water filter that can be connected to an existing tap. With the switch tap adapter you can choose between water directly from the tap or filtered water from the water filter.
Emergency drinking water filter
Our water filters are being 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 in need.
The AQUA Logic Gravity filter is a drinking water filter designed for situations where the regular water supply is unreliable due to water pollution or contamination. The filter is capable of producing high-quality, safe, and clean drinking water. It is particularly effective in environments heavily contaminated with microorganisms, providing an excellent solution for combating waterborne diseases such as Cholera. Additionally, the filter operates without the use of chemicals and is composed of maintenance-free and corrosion-resistant components.

1. Activated Carbon cylinder with a pore size of 1 micron
The activated carbon is made from 100% organic material (coconut shell) and has a very high adsorption capacity for odours, colour, taste, metals such as lead, as well as yeasts, chlorine, pharmaceutical residues, and other chemicals.
2. Ultrafiltration membranes with a pore size of 0.01–0.03 microns
Ultrafiltration membrames providing effective filtration against:
- Pathogenic organisms: Bacterial reduction of >99.9999% (including Cholera, Shigella, Typhus, Klebsiella terrigena, Legionella, and E. coli)
- Cysts/Protozoa: (including Giardia and Cryptosporidium)
- Micro- and Nano-plastics: Removes particles as small as 0.03 microns (30 nanometers)
All parts are BPA-Free. The filter works without the addition of chemicals and is made up of maintenance-free and corrosion-free parts.
How to use
1. Marking the Filter First Use Date
Use the supplied date sticker to note the date of first use. Stick it visibly on the filter housing. 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.
2. Installing the Filter
Unscrew the aerator (flow restrictor) from your tap. Then, firmly screw the water filter's tap adapter onto your tap. If necessary, use the provided adapter ring. If you have a tap with an internal thread, you can use the supplied adapter ring in combination with the rubber seal. For taps without threading, the separately available rubber tap adapter can be used.
3. Ready for Use
Once the tap is open, pull out the lever on the tap adapter to allow water to flow through the filter. When you turn off the tap, the lever will automatically spring back (Note: Due to built-up water pressure, it is normal for the water to continue flowing for a short while). It is recommended to not use the first batch of filtered water (ca. 5 liter) for consumption. After that, the filter is ready to provide clean and safe drinking water.
4. Deflate the Filter
Hold the filter upside down while it fills with water (with the lever pulled out). This allows any trapped air to escape from the filter.
Tip: Hold a cloth at the filter outlet to catch any water that may escape.
Maintenance
When the flow rate decreases, the filter element can be easily cleaned:
Disassemble the Filter
Place a bowl or towel under the filter. Hold the filter upside down, above the sink or a bowl, while turning the filter housing counterclockwise to open (you can use the supplied tensioner for this). Pull the filter element out of the housing using a twisting motion.
Cleaning the Filter Element
If the water flow slows down, the filter can be cleaned easily:
- Using the integrated Cleaning Pad, the filter surface can be firmly sanded clean (see image beside).

- Rinse the actived carbon surface. Make sure only clean water touches the water outlet. As a precaution, do not use the first liter of filtered water for consumption.
Reassemble the Filter
Make sure that the rubber sealing ring is correctly positioned and clean when closing the filter housing. Then close the filter housing by tightening it firmly.
Storage During Extended Absence
Wet Storage: Store the filter element in a sealed container or bag in the refrigerator.
Dry Storage: Let the filter air dry and store it in a clean place. 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.
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.
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.
