The bombas as pictured come in two sizes, to fit different sized garrafon necks, we have lately noted. They are very inexpensive, and perfect for getting that purified water from your garrafons (5 gallon containers). Filters? we have gone through several years without using any, always relied on water trucks to provide full garrafons we used for everything, a small cost to keep things healthy.
Now that we're desert camping north of the border, we carry a 15 gallon container and a spare 12 volt water pump to transfer into the fresh water tank, but also have one bomba and garrafon for drinking water. While we were in the south of Mexico we always had another garrafon outside, where we cooked. One never sees a water truck carrying the 5 gallon containers of water here in the SW desert. That did make life easy in Mexico. For us, water quality is always in question here, making the garrafon, filled from a water vending machine, a necessity.
