You can buy a box called an indoor dryer vent kit at home improvement stores and it manages to control most of the lint but not the water dumped into the air.
Venting electric dryer into attic.
Sometimes such as in town homes or condos it s not possible to vent a dryer through a wall outside.
The problem with attics.
The air is usually loaded with lint and if you don t vent it outside it can cause all kinds.
Dryer lint is also highly flammable.
That is the old material type tubing simply ended by a overhang side of the house where it exhaused into the attic and not outside.
The attic is usually colder than the rest of the house during the winter and that can create a problem for a dryer vent.
Some homeowners use a much simpler system of venting down into a bucket of water like in the photo at the top of this page.

For dryers that are located in a place where venting to the outside is difficult it s ok to simply vent the dryer into a container of water.

But we don t recommend it for two reasons.
A dryer vent should be vented outside.
Not all dryers will allow for this so be sure to check the owners manual to ensure it can be vented in this manner.
