Venting clothes dryers indoors is possible, but consider this option only when outdoor venting is not possible. The working mechanism of indoor venting is less effective compared to that of outdoor venting.
Clothes dryers involve the circulation of a lot of water vapor that causes problems in the house, especially mold and mildew growth and discomfort. Moreover, most houses are not equipped to withstand such a large amount of moisture.
There are many specially designed dryer vent products that minimize the downfalls of indoor clothes dryer venting. While such products do not offer the same experience as outdoor venting systems, they are a viable alternative when it is not possible to vent clothes dryers outdoors.
