Is water from a dehumidifier clean?

The water the dehumidifier collects is actually very clean water; comparable to distilled water. The condensed water is pure because when the water originally evaporated into the air, it left its impurities and minerals behind. So providing your coils are clean, you could collect the dripping water and drink it.

At what temperature does a dehumidifier stop working?

Most dehumidifiers should not be operated in temperatures below 60° F, since the moisture removed from the indoor air can freeze when it condenses on the cooling coils, which can damage the unit.

What makes a dehumidifier freeze up?

If your dehumidifier coils are freezing up and the room temperature is above 65 degrees Fahrenheit, there may be an issue with the humidity control. If the humidistat is not reading the humidity correctly, the compressor will stay on which can cause the coils to freeze up.
