It could also be that the interior humidity in your house is too high.

Interior humidity levels during winter should remain between 30 and 50 percent, experts said.

A large collection of house plants also adds to interior humidity.

The car's interior humidity is raised and lowered to increase comfort and prevent window fogging based on readings from other sensors.

(In some cases, drier outside air can be mixed with the wetter inside air to reduced interior humidity levels while maintaining system performance.)

The life-support readouts claimed the rebreather was fully functional, the interior humidity and temperature were exactly on-spec, but the system appeared to be supporting no load.

If so, it directs warm air through the defroster vents, increases the fresh air intake and, if necessary, uses the air-conditioning system to lower the car's interior humidity.

During the first months immediately after construction, minor problems with interior humidity and polystyrene ICFs may be evident as the concrete cures and can damage the drywall.

However, interior humidity can also be lowered by making certain there are exhaust fans in both the kitchen and bathrooms, by venting the dryer outside and by lowering the setting on the humidifier (if you have one).

New versions of phase-change indirect evaporative coolers use nothing but a fan and a supply of water to cool buildings without adding extra interior humidity (such as at McCarran Airport Las Vegas Nevada).

Although dehumidifiers might be used, heat pump hot water heaters also will act to cool and condense interior humidity (where it can be dumped into drains ) and dump the heat into the hot water tank.

As the interior air dewpoint temperature is an important basis for such rules, buildings with high interior humidities during cold weather (e.g., museums, swimming pools, humdified or poorly ventilated airtight homes) may require different rules, as can buildings with drier interior environments (such as highly ventilated buildings, warehouses).
