We think that the ‘best’ filtration system is
-microfiltration grid or paper to trap the bacteria from entering our mouths.
- large capacity to hold all the bacteria from the water after cleaning it
- portable so that we can carry it anywhere

A portable filter that can fully remove all the dirt or parasite in the water. The filter needs to be able to have different layers to remove them.

The tiny water molecules slip through the small pores, while biological and physical contaminants are held back by the membrane. As water passes through the pores, clean water is then released from the tap.it is also movable

# data[].attributes.body
There is a micro filtration inside the pump to clean the water passing through getting clean water.

WaterRoam is a portable pump, that filtrates dirty water and when the pump is used, dirty water will go through the hose and the micro filtration will filtrate it and come out the tap as clean water. They then install the pump onto villages or places without enough amount of clean water

# data[].attributes.body
Inside the pump, there is a micro filtration to trap the bacteria. When the bacteria is trapped, clean water will exit.

Some criterias of the “best” water filtration system:
- ability to remove suspended solids, bacterias and small particles  from water
- amount of time taken to filtrate water should not be long
- durability should be high (can withstand a lot of dirty water before being needed to change)
- portable

wateroam makes use of micro filtration by using the pump to create strong force to push the clean water through and trap the bacteria

# data[].attributes.body
Wateroam uses a micro filtration to remove the bacteria and makes only purewater come out

# data[].attributes.body
They use a portable technology to take the dirty water and use filtration to separate the clean water from bacteria by using a pump to create pressure that pushes the water through the microfilter

WaterRoam is a portable pump, that filtrates dirty water and when the pump is used, dirty water will go through the hose and come out the tap as clean water. I think that the filter is inside the hose, where the filtration of the water takes place before the water exits out the tap.
