How much water does it remove per day?

Costway rates it at about 22 pints per day under warm, humid conditions. Real output drops in cooler rooms, which is normal for compressor dehumidifiers.

Do I have to empty the tank often?

The tank holds about half a gallon, so in steady damp air you may empty it once or twice a day. You can attach a hose for continuous drainage instead.

What size room is it good for?

Treat it as a small-room unit for closets, bathrooms, laundry rooms and modest basements. The 1,200–1,500 sq. ft. figure is far beyond what a 9-pint unit handles in practice.

Does it have a humidistat or auto shutoff?

It shuts off automatically when the tank is full. It does not have a digital humidistat display, so you set it by its six modes rather than a target humidity percentage.

Is it loud enough to bother you at night?

The compressor is audible, and several owners say it is too loud for a bedroom. It is better suited to a room you are not sleeping in.

Does it need a filter?

No filter is required, so there is nothing to wash or replace. Wipe the grille and tank to keep it working well.

Our take on the Costway 9-Pint Portable Dehumidifier

The Costway 9-Pint Portable Dehumidifier is a compact compressor dehumidifier that pulls about 22 pints of moisture a day and holds it in a half-gallon tank. It offers six settings, auto shutoff when the tank fills, and ETL listing, and it is small and light enough to move between rooms. It suits closets, bathrooms, basements and small rooms better than large open spaces; the 1,200–1,500 sq. ft. claim is optimistic for a unit this size. Against larger-name dehumidifiers it is simpler and cheaper in features, with no humidistat readout or pump, and owners rate it well overall while noting the tank fills fast in damp air.
