Air out a mattress and pillows to reduce allergies and microorganisms. Even in the winter, airing indoors or outside reduces dust and bed bugs.

Every adult perspires and exfoliates while sleeping, which sheets and mattresses absorb. Moisture and skin cells in your bed make dust mites, and allergies thrive.

Allergens can irritate the skin, causing a runny nose, sore throat, or watery eyes. Because of this, your mattress may smell bad and need to be cleaned and deodorized often.

Why air mattresses?

Warmth and moisture will go into the sheets and mattress if you immediately make the bed. The trapped moisture will smell stale.
