What an 800 sq.ft unit is

An 800 sq.ft dehumidifier is a portable unit sized for a bedroom, bathroom, basement, or similarly sized room. It pulls moisture from the air and collects it in a tank you empty by hand. Most have a tank in the 50 to 98 ounce range, so you are dumping water every day or two in a damp space.

Tank, drain, and daily use

These units run on a small tank or a drain hose. A hose lets you skip the emptying routine, which matters in a basement or a room you do not visit daily. Without a hose, the tank fills and the unit shuts off until you dump it.

Auto shut off kicks in when the tank is full, so the unit does not overflow. Sleep mode drops the fan noise for use in a bedroom at night. A five-color LED light is a common extra, and it is mostly cosmetic.

Colors and placement

The selection includes black, gray, white, and yellow finishes. Size and shape matter more than color if the unit sits in a corner or behind furniture. Check the footprint against the spot you have in mind before buying.

Before you buy

800 sq.ft dehumidifier questions

How often do I empty the tank?

In a damp room, a 70 to 98 ounce tank usually needs emptying once a day.

Can I run it without emptying the tank?

Yes, if you attach a drain hose so water runs out continuously.

Will it shut off on its own?

Yes, auto shut off stops the unit when the tank is full.

Is sleep mode quiet enough for a bedroom?

Sleep mode lowers fan noise, so it is the setting to use overnight.
