No need to buy and replace expensive filters! You only need this Washable Dust Filter.
You should wash the dust filter approximately once per month. The dust filter slides off the air purifier like a sleeve. Wash the filter on either a gentle cycle or by hand using a mild detergent and cool water. Air-dry the filter.
DO NOT put the filter in the dryer. After the filter is dry simply slide it back on the air purifier.
