Motor And Airflow Noise Factor—One of the most important things to look for when purchasing a HEPA air cleaners is to get a unit that is quiet so you can watch TV and sleep while it is operating. All air cleaners are loud when they are operating on high speed. This is because high speed is for quickly clearing the room. Most people operate their HEPA air cleaners around medium speed for everyday use.
Most of the inexpensive department store and chain store HEPA air cleaners are often very loud due to the fact that they use low quality motors that are poorly balanced with bearings that wear out to make more noise.
