Unfortunately, in a home where there is not an air purifier, these contaminants most probably lurk in the air and they spread fast, thus predisposing those who are sensitive to the dangerous attacks.

    • Allergy Triggers

Allergy sufferers have specific reactions when they encounter certain allergens their immune systems are affected by. Generally, they are not sensitive to a single substance but rather to a variety of different allergens. When it comes to this health problem, the common triggers include pollen, mold spores, dust mites, pet dander, and medicines. While you have to stay away from the type of medicine that affects your allergies on your own, the rest of the common triggers can be eliminated with ease if you simply rely on an air purifier for allergies and asthma.
