This HEPA filter is for use with the NXT60, NXT85, and NXT85c dehumidifiers*. It sits behind the pre-filter on your Watchdog Crawl Space Dehumidifier. It is used as a replacement filter for the standard MERV-10 filter that is included with your dehumidifier. A HEPA filter is extremely effective at removing the smallest dirt and dust particles from the air. It is recommended that the filter be changed about once a year. It is not washable.
The N-202 comes in a 3 pack. The filter mesh may be blue or white. These filters measure 12" x 10" x .75".
