You won't find anything that filters much better than the factory filters. They filter really fine particles and therefore need regular attention, and they aren't cheap.
I put an airdog 4g low pressure pump on my truck and it feeds the factory pump, now I don't have to change the factory filters as much and the airdog filters have a much longer interval because of the size of the filters.
The H&S kit filters probably about the same as stock but uses cheaper filters and you can mount them where you like so they are easier to change.
