Most recirculating humidifiers are cool mist models that use evaporative humidification. This means a fan inside the unit pushes the water from the tank out into the air, but at the same time sucks in the water from the air and filters it back out. Much like a freezer, the machine has a special chemical that keeps the water moving. This simply means that you have to fill the tank less frequently. Although you do not need to change the water as often it is important to remember to clean the tank every so often.
Depending on the brand and make of the recirculating humidifier you may have to change or clean the filter as well. The cheapest and more Eco-friendly option is to rinse the filter out and reuse it a few times before replacing it with clean thing.
Most recirculating humidifier models are small and weight less than 25 pounds, the large tanks and fans allow up to 2400 feet coverage. Some cover enough feet to cover an entire house, but units are available to cover single rooms.
Generally people purchase humidifiers to protect their bodies and homes. Dry air can cause discomfort such as cracked lips and dry skin. The moisture in the air adds moisture to your body. Breathing in dry air can also cause nosebleeds.
Warm mist humidifiers relieve symptoms of flues and colds as well as sinus infections. Medicine can be added to these to relieve the tightness in chests during cold, making coughing less frequent and less painful.
Not only does moisture in the air add moisture to your skin, but it also adds moisture to the walls and ceilings in your home. This prevents the paint and wood from becoming dry and cracking. However, too much moisture can be trouble. It is important to purchase a hygrometer to oversee the moisture in your home.
Most recirculating humidifiers include digital controls that tell you the moisture in the air. If it does not tell you how much moisture is existent, use a hygrometer and then set the digital control at the necessary percentage.
Recirculating humidifiers are available at most hardware stores, but be aware the convenience will cost more.
