It has parts to vent it. I purchased the indoor venting kit to go with the dryer. It doesn’t push allot of lint threw I see very little getting threw. I have cats so cat fur is always on everything and the lint filter inside the dryer works well to catch allot of the lint and cat fur. Also I do not over load the dryer I only do small loads and use a water extractor spin dryer to remove allot of the water since my washer don’t have a spin cycle so dry time is under 20 minutes with the extractor. I enjoy using this dryer and its compact size fits well in the small amount of space I have
