I bought this unit to replace my previous non-brand unit for my 200 sq. ft. wood shop. The old one was ok but seemed to only blow to one side. On high speed, it made my shop just tolerable. My new unit works great. It really cools my shop (on low speed) and allows me to work for as long as I want and be very comfortable. I live in south Texas along the Gulf where we have high humidity and heat indexes in the 110-115 degree range pretty much every day. My LG works great.
