There's a product out there that you can put inline on your dryer exhaust vent. It's a simple device that let's you divert air flow into your home through a vent instead of it going outside the house. I thought this would be a good way to cut down on heating costs this winter but I've heard it sometimes creates too much dust and moisture inside the home. In winter, I don't have humidity problems, but I don't want a lot of dust.
Is this kind of product good and safe to use? What are the pros and cons?
Thanks for you advice.
