Humidifiers can use hot steam or cool vapor. Most people do not realize the effects and consequences of using either. Cool mist seems better for a hot environment, however they collect bacteria because of the cool temperatures and hidden compartments that are out of reach for cleaning.
The spray moistens the environment by hot steam. No particles can be irritating and works like the medicine Vicks, in order to facilitate breathing. Its use is recommended in people with colds or respiratory infections.
Cold vapor produce. The cold steam humidifier contains a container which is filled with water. Using a system consisting of a rotating disc, the water is transformed into a cold mist, so that the air is moistened.
Humidifiers need distilled water and must be kept very clean, because, if the water is not hot, it can easily grow bacteria or fungi. But they have the advantage to be safer because they produce hot steam and therefore no risk of burns.
Cold mist vaporizers can encourage biological allergens, including mold, mildew and cockroaches, that can trigger asthma and encourage viruses and bacteria. Remedy: Use and clean them according to manufacturers' directions. Refill daily with fresh water.
The last ultrasonic humidifiers are like Chicco Globe, which are quieter and produce super micro mist particles that remain suspended in the air longer. This can regulate the flow of steam and when cold, can also be used in summer. The disadvantage of cool mist vaporizer is that they are more expensive.
When making your selection, first determine the moisture output capacity (gallons per day) of the humidifier that you need. Although this is somewhat dependent on your climate, a newer airtight, 2,000 square feet. house typically needs about 5 gallons per day and a loose one needs about 10 gallons per day to maintain an adequate humidity level.
When the indoor air is too dry, moisture from your skin evaporates at a very rapid rate even though you are not aware of the moisture loss.
This evaporation lowers your skin temperature.
A home with forced-air heating may have an automated humidifier integrated into the
duct work, but keeping relative humidity at an optimum 50-60 percent, needed for
healthy houseplants, is very difficult. Low humidity in most of our homes during the
winter months is a given. The already low humidity of the dry winter air is pushed lower
by the heated air in a home.
Research has shown that the quality of indoor air can be worse than that of outdoor air. Many homes are built or remodeled more tightly, without regard to the factors that assure fresh and healthy indoor air. Our homes today contain many furnishings, appliances and products that can affect indoor air quality.
If you opt to invest in a humidifier, keep in mind that you may be purchasing a device that is not subject to FDA regulation. Many "department store" humidifiers that consumers purchase directly off the shelf are not regulated by FDA because they make no medical claims. Some of these machines do no more than promise to increase the comfort level in your home.
