Air washers are clever little air quality appliances that have been popular in Europe for years, but have only recently jumped across the pond to the U.S. market. An air washer is a hybrid appliance, a combination of an air purifier and a humidifier. Like conventional humidifiers, air washers add therapeutic moisture to the air. And, like a conventional air purifier, an air washer removes symptom-triggering allergens from the air. Therefore, they are capable of soothing your uncomfortable dry air symptoms and easing your allergies. They're ideal for you if you suffer from light to moderate allergies or you just want to improve your indoor air quality in the wintertime. You might also consider using one year-round if you live in a dry climate.
