I smoke. I have hepa filters and a ttw kitchen vent, non adjustable speed. It is winter, ave 20 f. If i cover half half the vent with something like a plastic bag does that cut down the air exchange? Or does it just suck faster through the non covered part? Without quitting smoking (guests too) im looking at the heating bill.

A restriction will cut air flow. I'm not sure how much, but 50% cover
may not be a 50% reduction. You are also putting some load on the motor
so it may reduced motor life.

Thanks Ed. I never figured i would be asking how to cut down on Suck. That vent is like having 2 doors open in winter. I just needed less suck.

why should a smoker be concerned with costs? tobacco costs so much and makes a large percentage of smokers very ill, or kills them........

my dad has reoccuring bladder cancer from smoking. his future is terrible.

my one time fiances dad was a lifetime smoker.

i got invited to see him just a couple days before he died of COPD.

smoking is just plain insane

The best solution here is a fresh air heat exchanger, which will
save most of the heat that would have been lost when swapping
air. That way you can have the same air exchange with much less
heat loss.
