The first frost is a good sign for seasonal allergy suffers, but for those who have indoor allergies, it is a sign that the suffering is about to get worse. Wintertime allergies are usually triggered by allergens trapped in the home, where they pose a risk to respiratory health. These irritants are always present, but during the winter months they tend to multiply because people keep their windows closed and there is little circulation of fresh air. It is estimated that up to 72 trillion allergens make their way into the home every day. Allergies affect millions of people in the United States. In fact, more than 50 percent of the U.S. population tested positive for one or more allergens, according to the National Health and Nutrition Examination Survey. Allergy symptoms -stuffy or runny nose, itchy eyes, sneezing and wheezing - are similar to those of a cold. So how can you tell if you are suffering from allergies or a cold? According to the American Academy of Allergy, Asthma & Immunology, here are the major differences:

Colds

• Results from a virus infection.
• Symptoms may also include a fever and aches and pains.
• Usually takes a few days to hit full force.
• Symptoms should clear up within several days to a week.

Allergies

• Symptoms begin almost immediately after exposure to an allergen.
• Symptoms last as long as they are exposed to the allergen.
• If the allergen is present year-round, symptoms may be chronic.

A whole-home air cleaner, such as the Aprilaire Model 5000, is an efficient and effective way to reduce all airborne contaminates in a home, including dust, pollen and bacteria.
Installed by a heating and cooling contractor, the system requires little maintenance - the filter in a whole-home air cleaner only needs to be changed once a year. When using a whole-home air cleaner, be sure to run the fan continuously on the heating and cooling system.
