The SEAIRA GLOBAL W518 HEPA filter is for use with Seaira Watchdog 550 dehumidifiers. It sits behind the pre-filter on your Watchdog Crawl Space Dehumidifier and serves as a replacement for the standard MERV-8 filter. HEPA filters are effective at removing dirt and dust particles from the air. It is recommended that the filter be changed about once a year.
The W-518 HEPA filter improves air cleanliness in crawl spaces and basements. Built as a direct replacement for the factory filter, installation is simple and maintenance is easy.
