I currently have a “30 micron” Keystone sediment filter installed on my main water line. Would a “20 micron” offer better filtration?

No, not necessarily. A “micron” is a unit of measure equal to 25,000th of an inch. A human hair is about 50 to 75 microns thick. A filter cartridge with a 30 micron rating may be the best choice for a given application such as sand removal or heavy sediment removal. Switching to a “tighter” filter like a 20 micron cartridge in this instance, might actually cause the filter to plug up much sooner than the original 30 micron filter.
