Product review (5 stars): Very easy to install
My Dryer had gotten to the point that it would take 3 cycles to dry clothes due to the 20' long tube to the outside of the house being clogged up with lint. I sealed it off inside and outside and installed this box in my laundry room. Very easy to install, and works great. My dryer will now dry large loads of clothes in one cycle, which saves me allot of money in electricity costs. Plus I get the added benefit of free heat for the house. Highly recommend. Also, this probably goes without saying, but this is ONLY for use with electric dryers. If you have a gas dryer it MUST be vented to the outside of the home, as carbonmonoxide can and will KILL YOU.
