Specific Components Maintenance
Actual maintenance plan may vary from installation to installation, yet there are several key components from
maintenance prospective.
If needed, contact respective component manufacturer for additional maintenance information.
Filters

Ensure air filters are clean. Dirty air filters will negatively affect dehumidifier performance and lifetime

Frequency of filters replacement will vary based on air quality, dehumidifier usage, facility type, etc. Make
sure to replace filters regularly

Replace with filters of equivalent size and rating – refer to dehumidifier details (compartment stickers, etc.)
