You can humidify the air two ways: warm mist and cool mist. Warm mist humidifiers heat water to the boiling point and release the mist into the air. Cool mist humidifiers create a fog when the submerged disc in the water tank spins rapidly. Typically, cool mist humidifiers are less expensive than warm mist humidifiers because they don't require a heating element. You can find humidifiers that offer both warm and cool mist. These can be beneficial depending on how much you use your humidifier.
Dry air costs more to heat than warm air. Using a humidifier will moisten the air, making it warmer, meaning you can turn the thermostat down a few degrees. This will lessen the work of the furnace, lowering heating costs.
Dry air irritates sinuses and causes skin to become itchy and flaky. Adding a humidifier creates moister air, which helps alleviate dry sinuses and skin. Moist air cuts down on particles in the air, such as dust and pet dander, which can offer relief for those with allergies and breathing problems.
When furniture, paintings and other decor become dry, they can fall into disrepair. Furniture begins to creak, paintings start to flake and clay items can begin to crumble. Adding a humidifier will moisten the air, which will help keep decor and furniture in usable and presentable condition.
Warm air cannot create static. Therefore, adding a humidifier to a home with dry air will eliminate the need to pause and steel oneself before touching the light switch or another family member after walking across a carpeted area.
