• Collections | Ventilation

How to get smoke from fireplaces and stoves outside, along with damp from clothes, for example, was a problem for pioneers. There was no ducting, no fans, no air filters, or other ventilation and indoor air quality products back in the 19th Century, or even early in the 20th Century. Today you take these appliances for granted, hidden away in walls and ceilings. These 63 items show evolving ventilation that helped solved those problems.
