Drawing inspiration from the comb jelly’s porous skin

and deep water habitat, we have decided to create a filtre

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

filtre 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-filtre. 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 filtre.

This kind of filtre 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
