When seasons change so does the quality of the air we breathe when winter comes, the air gets dried and it can cause cold-weather related ailments. Humidifiers work by putting the moisture back into the air. This could be helpful in easing breathing difficulties and make breathing comfortably in dry, cold air. A humidifier does more than just make the air comfortable for breathing, but it increases the humidity levels in a room. This is important because over time, dry air can affect the infrastructure, especially wooden floors and furniture. Paint and wallpaper also tend to peel off when the humidity levels in a house are too low.
Humidifies are defined as devices that emit water steam or water vapor to increase the moisture levels in the air. There are (on ChooseHumidifier.com) five different types of humidifiers with different attributes:
1. Central Humidifiers
These are often built-in with the home air-conditioning system and are designed to humidify larger areas.
2. Ultrasonic humidifiers
These produce a cool mist and an ultrasonic vibration through a diaphragm. The vibrations create micro-fine water particles that are blown into the air.
3. Impeller humidifiers
These have a rotating disk which produces a cool mist that is at room temperature. The mist can make the temperature of the room fall. There are warm mist distributors that do the opposite by distributing heated steam.
An evaporative humidifier has an internal fan that pulls the air in the unit, passes it through a water saturated wick and then lets the fan propel the moisture saturated air out to circulate in your room.
5. Steam vaporizer humidifiers
These humidifiers use electricity to heat water and turn it into steam. The steam is allowed to cool down before it is dispersed out of the unit into the surrounding air.
When do you need a humidifier: what are the ideal humidity levels for any home
The amount of humidity varies from place to place and from one season to another. When we consider changing seasons, summer has higher humidity levels. The ideal level for a residential home is 30-50%. Low humidity causes dry skin, throat irritations, itchy eyes and breathing ailments. Higher humidity levels make a room feel stuffy, causes condensation on floors, walls and furniture that can lead to damage. A high humidity also triggers the growth of mold, bacteria and allergens that can cause respiratory ailments. There are ideal humidity levels that ensures the right amount of moisture and air temperature, but before you rush out to buy a humidifier, invest in an instrument that can measure humidity levels called a Hygrometer. Some humidifiers have a built in meter and automatically adjusts themselves to maintain steady and healthy humidity levels.
