Description of Coway Air & Sound Air Purifiers

The Air & Sound air purifier offers affordable HEPA filtration for bedrooms up to 155 sq. ft.

A carbon-charcoal pre-filter helps reduces common household odors. Three airflow speeds and a change-filter indicator take the guess work out of ownership. 3-year warranty.
