Which is fine for filtering particulates, but does nothing to resolve the issues of CO2 buildup, natural gas appliance fumes, formaldehyde from composite wood products or other off-gassing, etc. For proper indoor air quality you need both filtration and fresh air intake.
- gniv 3y agoAlways-on air purifier + opening windows a couple of times a day is cheap and effective.
- jefftk 3y agoSure, but that is less the remit of the CDC.
- Abekkus 3y agoYou want about 15CFM fresh air per person to address CO2, which is 14x less outdoor ventilation than 5eACH recommended interior filtering & ventilation. For my small, crowded house, at least.
