filter
The WB-601J filter is a component of the Wisher filter system. It is an advanced whole house particulate removal filter that is designed to remove allergens and various airborne contaminants in both residential and commercial settings. The filter is designed with a three-tiered system for maximum filtration efficiency. The first tier is made up of a 5-micron coarse particle pre-filter, which captures coarse particles such as dirt, dust, and hair. The second Tier is a 1-micron fine particle pre-filter, which captures finer particles such as bacteria, virus, mold, and pollen. The third and final tier is a 0.3-micron pleated filter, which is capable of removing ultra-fine particles such as smoke and cigarette smoke. The filter is also designed to provide an efficient airflow, so energy costs are minimized while air quality benefits are maximized.
