Re: Cold air coming in from dryer vent Really? Cleaning? Makes sense.
Though I'm curious to see if this lasts.
Hot air vented is very very humid.
I'd be surprised if the thing didn't freeze open with the cold temps we're getting these days: -5F before wind chill factor.
I don't know what you meant by steel grill. How would it help aside from being heavier thus close more? maybe?
As for the grills, ya I saw those. If I have to replace mine, I'll get one of those. Not much more than a normal grill.
