University of Utah Health Department offers some tips for understanding the air in your house and the air-quality appliances that can alter it.
Air filters – The purpose of an air-filtration system is to pull mold, pollen, dust mites, and other particulates out of household air. Health benefits include relief for people with severe allergies or asthma, but it’s not a necessity for the average person. Air-filtration systems need to be meticulously maintained. Changing the filters according to the manufacturers’ instructions is a must for the long-term success of the system.
Dehumidifiers – The purpose of a dehumidifier is to remove moisture from the air. This curbs the growth of mold and dust mites. They are most needed in parts of the house where humidity collects, such as damp basements. Dehumidifiers are most critical in households in humid climates with old people or very young children, or for families with a history of allergies or asthma.
Humidifiers – The purpose of humidifiers are to add moisture to the air which tends to become dry during winter in cold climates where home heating systems are in constant use. This dry air can dry out and irritate your eyes, throat, and lungs and dry out a person’s skin. Humidifiers may help those suffering from sore throats, headaches, nose bleeds, and coughs related to dry air.
