4. Tosot 4,500 Sq. Ft. Dehumidifier – The Compact Option

TOSOT 50 Pint with Internal Pump 4,500 Sq Ft...
  • 4,500 SQ FT: Our dehumidifier can remove up to 50 pints of water every 24 hours (same as 70 Pint units under 2012 DOE standard.) A lower humidity level allows your AC system to work more efficiently because it's easier to change the temperature of dry air compared to moist, super-humid air.
  • INTERNAL PUMP: The internal pump automatically removes collected water from the dehumidifier so you never experience downtime due to a full water bucket. Water can be pumped sideways or vertically up to 16 feet away. Water will collect in the bucket until it's almost full, then the internal pump will automatically start up to remove the collected water.
  • REAL-TIME MONITORING: After choosing a target humidity level the control panel will display the current humidity level. The dehumidifier will power off after reaching the target you set. If you want the dehumidifier to run nonstop regardless of the current humidity level, press the minus button until the control panel displays "NS." The dehumidifier will run until the drain bucket is full, which will never happen if you have the continuous drain set up.
  • SOLID MATERIAL: All plastic components are made from solid ABS for increased durability. We use solid-copper tubing in our internal lines for better heat transfer and received a UL94 flame-retardant classification of V-0, which means even if the unit were to catch on fire, the flame would stop within 10 seconds.
  • 30 YEARS' EXPERIENCE: As the largest residential AC producer in the world, we have a pretty good idea about how to make quality products. If you have any problems or concerns, our customer service team is happy to assist you.
