Low-cost off-the shelf water filtration product?

Can anyone suggest a low-cost off-the shelf water filtration product? The communities which the water supply is to be installed are very small so it may make sense to install purification/filtration within households rather than for the community as a whole. The supply is relatively clean but may contain some particulates and bacteria.

Past experience here has been with larger-scale concrete installations which use sand-filtration. The budget for these sites is particularly low and time-scale is also short. Any suggestions for good easy-to-install devices would be appreciated!
