WASHABLE & REUSABLE ! AIRAID's direct replacement air filters feature a ''FIVE LAYER'' filtration. Most washable filters use only three or four layers of oiled cotton gauze.
AIRAID utilizes five layers to assure the cleanest air possible. The fifth and ''last layer of defense'' is a synthetic media that produces the cleanest air of any washable filter.
AIRAID provides the optimum balance between maximum airflow and maximum filtration.
