Warm weather brings people outdoors where they are greeted with sunshine and breezes, as well as allergens like tree, grass and weed pollen. This is a big problem if you have allergies or asthma, and to make matters worse, research shows allergy season is starting earlier and lasting longer than usual.
Good indoor air quality is an important part of a healthy living space, and it is a particular concern for the 25 million Americans living with asthma and the more than 50 million Americans experiencing various types of allergies each year. About 24 million Americans have seasonal allergic rhinitis, more commonly referred to as “hay fever.”
