Tractor and sprayer cabs have long since used seals, filters and fan(s) to lift cabin pressure over that of outside air. The notion is that dust can’t easily get in, so the operator breathes clearer air. It works; at least until seals age and/or maintenance standards drop. Yet even most factory-fresh conventional systems have limits. Their relatively simple intake filters can’t handle very fine dust. Neither can they extract gases; vapours (that is, molecules from a liquid or solid diffused in air); aerosols (solid or liquid particles suspended in air), or stinks in general.
