Seaira Global W915 Pre-filter Watchdog 900 Dehumidifier 3 Pack

Product Description

The SEAIRA GLOBAL W915 is a replacement pre-filter designed for use with the Seaira Watchdog 900 first-generation dehumidifier. It mounts at the inlet end of the unit, positioned directly in front of the main filter, where it captures airborne particles before they reach the primary filtration media. This extends the life of the main filter and helps maintain consistent airflow through the system. The W915 is both washable and vacuumable, making it a reusable maintenance item. Each package contains 3 pre-filters. Installation and periodic filter maintenance are typically handled by pool service professionals or HVAC technicians servicing dehumidification equipment.

The W915 pre-filter is designed for residential and commercial applications where a Watchdog 900 first-generation dehumidifier is installed. These units are commonly found in indoor pool rooms, natatoriums, and other high-humidity environments. The pre-filter slots into the inlet end of the dehumidifier, providing a first stage of particle removal that protects the main filter from premature loading. A pre-filter ships standard with new Watchdog 900 units; the W915 3-pack is intended as a replacement supply for ongoing maintenance intervals.

Compatibility

Installation Notes

Pre-filter servicing on dehumidification equipment is typically performed by pool service technicians or HVAC professionals familiar with indoor-air-quality systems. Before removing or installing the filter, power down the dehumidifier at the disconnect or control panel. The pre-filter slides into the inlet end of the unit and should be seated flush before returning the unit to service. Inspect the pre-filter at regular maintenance intervals and wash or vacuum as needed before full replacement.
