| > There’s no way around the production of combustion byproducts, but as the article states this is managed with proper ventilation - something that most builders skimp on. In theory. In 2014, a group of researchers in Baltimore ran a study with 78 homes with gas stoves to understand the most effective ways to reduce indoor air pollution. In one group of homes, they replaced gas stoves with electric stoves: in this group, NO2 pollution levels fell by 50%. (Apparently the remaining NO2 probably came from cars and other sources of pollution outside). In another group of homes, they gave homeowners an air purifier with a carbon filter and NO2 levels fell by 22%. In the last group, they installed range hoods: in this final group they found no significant difference in NO2 pollution. * https://pubmed.ncbi.nlm.nih.gov/24329966/ LBNL found that range hoods sometimes captured only 55% of pollutants like NO2: * https://pubmed.ncbi.nlm.nih.gov/22044446/ Another study found it 30%: * https://pubs.acs.org/doi/10.1021/es3001079 Even with range hoods, results can vary even for the same range, see (e.g.): > These studies found that for many range hoods, [capture efficiency] is much higher for the back than for the front cooktop burners. * https://www.sciencedirect.com/science/article/abs/pii/S03601... * https://phys.org/news/2012-05-kitchen-exhaust-fans-vary-effe... Some gas stoves leak pollution even when they are turned off (are you planning to run a vent 24/7?): * https://sustainability.stanford.edu/news/climate-and-health-... Of course blaming ventilation is a standard go-to response from industry: > “Ventilation is really where this discussion should be, rather than banning one particular type of technology,” said Jill Notini, a vice president with the Washington-based [Association of Home Appliance Manufacturers] trade group. “Banning one type of a cooking appliance is not going to address the concerns about overall indoor air quality. We may need some behavior change, we may need [people] to turn on their hoods when cooking.” * https://www.bnnbloomberg.ca/us-safety-agency-to-consider-ban... It's probably a lot easier to prevent pollution in the first place as compared to dealing with it after the fact. |
It certainly is but if someone’s informed they’re the consenting adult to make the decision they want.
Interesting venting didn’t make a difference but an air purifier did - this definitely doesn’t sound intuitive to me. Maybe venting shouldn’t be implemented as a hood, but something closer to the burners themselves?
