Dom Franks suggests that opening a window is the simplest way to improve ventilation, followed by using fans to accelerate air transfer. For situations where opening windows is difficult due to weather, he mentions energy recovery ventilators (ERVs) as a more advanced solution, with some new products resembling window AC units offering this functionality.
“Simplest is to open a window.”
“You can also use fans to accelerate air transfer into or out of the room.”
“If it's really cold or really hot outside, that becomes more difficult. So you can use a system called an energy recovery ventilator or ERV.”
