Has Anyone Built an Outside Air Ventilator?
I noticed yesterday evening that my inside temperature was 80, which is where my thermostat is set, but it was 76 outside. It made me wonder if I could build something to trade for outside air. Maybe with a second thermostat?
I know that the simplest thing is to open a window, but I actually have a lot of outside allergies at this time of year and would rather be able to HEPA filter the air.
