Take the tour ×  I live in a bungalow with a bathroom on both
levels. The bathrooms both have exhaust vents. Outside of each
bathroom is a ceiling vent. The previous owner stuck towels in
these to block them off. When I removed the towels I felt cold
air (it's winter right now) falling down, so I put them back.
When I had them out, I could see the vent hoses go back towards
the bathrooms. With the towels out I turned on a fan in the
bathroom and I can feel air being blown by it to the vent
outside of the bathroom. It seems like they are connected.  My
question is this. What purpose do these vents serve? Is it okay
to have them blocked? Should I be concerned?  I have electric
heat, so I'm guessing that it might be a way to help bring in
fresh air?  Any thoughts?  Bungalow was built in 1978 in
Ontario, Canada.  The vent in my bathroom seems to be connected
to a ceiling vent just outside of the bathroom. Why?
