I own a salon and day spa in West Plains, MO. We are a full service salon and also have spa treatment and chiropractic rooms. The smell from the perms was filtering into my treatment rooms and was not pleasant for anyone in the salon. After receiving the Aerovex system, we put the unit to the test. We had two customers receiving perms at the same time our chiropractor had appointments. Very quickly after turning on the unit, our stylists, chiropractor, and customers were not able to smell the perm solution at all. I am very happy with my purchase and my stylists and customers appreciate how well your system works. I am also excited to be able to market that my salon and spa offers the clean air Aerovex system. The system really does work!
