If the water you expect to filter is anything but cleaning "looking"
(i.e. murky, muddy, green, etc) use a prefilter like the Sweetwater
Siltstopper (with replaceable, light, cheap elements. I find that I
brush the acutal filter element infrequently, and years go by beI
acutally need to replace it.

I'm a fan of the MSR Sweetwater filter. It saved our butts one day when
we exercised poor water conservation strategy. I dropped this thing into
a pit of green algae-stained water and it came out.. well... a little
green, but still potable. I didn't get sick from the experience.
 
Copied straight from the MSR website (and apart from the science-stuff,
I can attest to the validity of everything here). My only complaint is
the filters are expensive - nearly half the cost of a new device.
 

Fast
Pumps water on both up and down strokes for a fast flow rate of 1.25
liters per minute. 
Easy to Use
Unique lever-action pump handle has a 4-to-1 mechanical advantage, so
you don't have to work as hard. 
Lightweight
Weighing just 11 oz., it's one of the lightest filters on the market. 
Compact
Handle folds flat when not in use for easy packing and storage. 
Dependable
Eliminates over 99.9999% of all waterborne bacteria and 99.9% of common
protozoan parasites, such as giardia and cryptosporidia. 
Simple to Maintain
Simple brushing will restore a clogged filter, and the pump lets you
know when the filter needs replacing (each cartridge filters up to 200
gallons of water).
