K and N filters are good. It's down to proper cleaning and re-oiling the cotton filter. It's the oil that traps the dust, not the cotton. I race off road in Land Rover based vehicles, petrol V8 engines, and never had an issue with poor filtering. Also run K and N in my truck. And besides that, there is very little issue with dust here in Scotland! Rains every day! 🤣
