Sawyer PointONE water filters are just 4 inches long and less than 8 ounces and can attach to any common plastic bucket or container.  They retail for $58 each.

The Sawer PointONE filter is a point of use system.  Since there is such a high flow rate, it eliminates the need to store water which reduces the chances of water being contaminated after it's filtered.  The only external force required for the system to function is gravity.  The Sawyer PointONE can deliver 1 liter of clean water in 60 seconds.  One filter can serve as many as 7 families or 40+ people for at least 10 years, if it is back flushed at least once per week.

All Sawyer filters deliver 0.1 absolute microns biological filtration, removing 7 log (99.99999%) of all bacteria like Salmonella, E. Coli, Vibrio cholera and Salmonella typhi (which cause Cholera and Typhoid,) and 6 log (99.9999%) of all protozoa such as Giardia and Cryptosporidium.
