Built for Commercial-Grade Reliability

This 90 pint dehumidifier is engineered for continuous duty in crawl spaces, basements, and commercial areas where downtime isn't an option.

90 PPD AHAM / 198 PPD Saturation — moves serious volumes of moisture in large or severely damp spaces up to 2,600 sq. ft.
Automatic Defrost — built-in sensors trigger a defrost cycle before frost can build up on the coils, keeping performance steady in cold spaces.
Memory Restart — picks up right where it left off after a power outage, so you're never stuck resetting it after a storm.
Built-In Condensate Pump — pumps water up to 14.7 ft high or 19.6 ft away, so you're not limited to gravity-drain-only locations.
C-ETL Certified & MERV-1 Filtered — meets strict electrical safety standards while the washable filter keeps air quality in check.

100% Hands-Free Drainage

Run a gravity drain hose to a nearby floor drain, or let the built-in pump push water up to 14.7 ft up or 19.6 ft (6 m) away — ideal for hanging installs or crawl spaces without a low drain point nearby.
