The product works however the quality of the motor is suspect. This is the second Austin Air Bedroom air purifier I ordered. the first on required a replacement because the motor vibrated so much it was impossible to use. The replacement has worked well for the past few years. This one has a slight fut noticeable vibration and we cannot use it in the bedroom as it affects our ability to sleep. I am contemplating returning it.


tengo condiciones pulmonares q aunque no me complican mucho , pueden ser fatales sin su debida atencion. Este equipo esta haciendo la diferencia.


This is the 4th Austin Air we have purchased over the past 20 years. Previous 3 were given to our children when they moved out. We have always been pleased with the build quality and reliability. This time we purchased the Bedroom machine for the 5 stage filter capabilities.
