Like older children and adults, babies can also suffer from allergies depending on the foods they eat, harmful airborne pollutants they inhale, and things they touch. Unfortunately, it can hard to figure out what’s wrong with your baby because they can’t express the symptoms they experience when they have an allergic reaction.

According to the American Academy of Allergy, Asthma, & Immunology, allergic reactions happen when your body’s immune system overreacts to a harmless substance known as an allergen. Symptoms can include a runny nose, sneezing, itching, hives, rashes, and more. It would also be helpful if you knew that allergies could also pass on.

According to the American Academy of Pediatrics (AAP), if one parent has allergies, their child is 25 percent more likely to have allergies, according to the American Academy of Pediatrics (AAP). If both parents have allergies, the child’s risk of allergies increases 60 to 70 percent, the AAP also notes.

So how do you stop allergies? An air purifier is a wise choice to eliminate harmful airborne pollutants, such as allergens, in your baby’s room. These specially designed units filter out dangerous airborne allergens, including dust, odors, smoke, pet dander, dust mites, mold spores, and more.

Using an air purifier in your baby’s room can help ensure that you have a healthy baby, but also your child is breathing healthy, clean air at all times. An air purifier can also improve the quality of sleep your child gets and help reduce asthma symptoms.
