Water Filtration Bottle
A sealed, stainless steel container which can filter 570 ml (20 oz) of water to make it potable. The container’s filter can purify around 5000 L (1100 gal) before it stops working and needs to be replaced. It filters out objects bigger than 15 nm—including viruses, bacteria, and cysts. Once a filter has reached its limit, it will not allow contaminated water to be drunk.[1]
