Educated Consumer

Larry from Homewood, IL– Verified Buyer

This well known manufacturer C.O. is quality it does the job as the larger high end ones without over spending. I tested the air it passed with flying colors read the instructions it should be mounted in the center of the hallway if your house is slightly larger or two levels you might want to purchase two.
