> Most of the problems with indoor pollution can almost certainly be more cheaply mediated by adding building codes requiring venting range hoods. As houses become increasingly more energy efficient, the cost of providing conditioned air only increases. Venting that air willy nilly to the outside has a real financial and climate cost. All rangehoods in new construction should be mandated come with sensors that auto adjust the power based on detected particulate levels. With the old school dumb rangehoods, most people never bother constantly touching a bunch of oil smeared buttons to adjust the speed and just have it on full blast the entire time. You save a couple of hundred dollars going with the non-sensor version but its a false economy as it silently increases your HVAC bill and ERV filter replacement costs over time.
