The SEAIRA GLOBAL N200 is a replacement pre-filter pack designed for use with NXT and Watchdog series dehumidifiers. The pre-filter mounts at the inlet end of the dehumidifier, positioned directly in front of the main filter media. Its role is to capture airborne particles before they reach the primary filter, extending main filter service life and maintaining airflow efficiency. Each filter measures 12 inches x 9 inches x 0.375 inches. The N200 is washable and can be vacuumed for reuse, making it suitable for routine maintenance schedules in high-humidity environments. This pack contains three replacement filters.
This pre-filter is intended for residential and light commercial dehumidification systems where inlet air quality and filter protection are part of a regular service routine. It is commonly installed in crawl space, basement, and mechanical room applications where dehumidifiers run continuously or in extended cycles. Service technicians and facility maintenance staff typically handle filter replacement as part of scheduled preventive maintenance visits.
Compatible with SEAIRA GLOBAL NXT60, Watchdog600C, NXT85, and NXT85C dehumidifiers. Note: the NXT120 and NXT120C Series require the N1200 Pre-Filter and are not compatible with the N200.
Filter replacement and cleaning should be performed by a qualified HVAC technician or trained maintenance professional. Power down and unplug the dehumidifier before removing or installing any filter components. The pre-filter slides into the inlet end of the unit and should be seated securely before returning the dehumidifier to service. If washing the filter, allow it to dry completely before reinstalling to prevent moisture carryover into the unit.
