Review on 🌬️ Vornado TRANSOM Window Fan - 4 Speeds, Remote Control, Reversible Exhaust Mode, Weather Resistant Case - White by Katrina Harrison

I used to always use two-fan units. In fact, it's a wide squirrel fan. You can leave it on your window and rest assured that it will let air through and remain weatherproof. This fan also makes your window soundproof, unlike traditional fans. The inserts provided were great and high quality for easy installation. It is an ideal window protection fan. After installation, attach blocks or screws to the upper window pane to prevent it from being lifted from the outside.
