A micron (1000th of a millimetre) rating tells you the distance between the pieces of filter media. This determines the size of the particles that will be able to pass through the filter e.g: a 50-micron filter will let through larger particles than a 5-micron filter. Traps sediment, dirt, silt and rust.
If using a water filter, ensure the pump is strong enough to overcome the friction from the filter.
