Drawing inspiration from the comb jelly’s porous skin and deep water habitat, we have decided to create a filter for large bodies of water that will afford its users drinkable


We intend for it to be used in two different kinds of environments. Firstly, as a convenient tool for nature explorers such as campers to throw into a lake or river to collect and filter water for them. Secondly, in places where fresh, drinkable water is not easily accessible


To construct our filter keeping in mind both sustainability and disassembly, we’ve decided to use primarily PLA. PLA is polylactic Acid. It is a thermoplastic polymer, making it. strong and durable. It is made from renewable sources, most often corn starch. It is considered a bioplastic as it is derived from biomass. It is most similar to polypropylene

or polyethylene. It is 100% biodegradable and can also be recycled into new products. We intend to build the body of our filter out of PLA, as well as the skeleton that holds it.

Water Filtration

After researching different ways to naturally and sustainably filter water, we’ve decided to use gravel, sand and activated carbon for our filter. The H2Orb floats, and is meant to be left in a body of water to fill itself up and store the water it has filtered for easy access.


The ingredients for our filter constitute a bio-filter. These are a great alternative to non-natural, commercial filters. Though they will not filter out every pathogen in the water, they will make it safe enough to drink, letting your body fight off the few that may not be eliminated by the filter. This kind of filter is a three layer filter, and each component plays its own role in purifying the water. Gravel removes large pieces of debris from the water. Next, the sand eliminates smaller particles that had slipped through the gravel. Lastly, the activated carbon filters through the rest of unwanted bacteria and chemicals through its many porous surfaces.
