With the fall college semester right around the corner, it’s time to start making a list of dorm room essentials. If you’re a parent of incoming freshmen, they’ll need items like bedding, including twin extra-long sheets — school supplies, laptops, refrigerators, and cleaning supplies. In the age of the coronavirus, your child will also need hand sanitizer, disinfectant spray, and protective masks.

Although dorm rooms are an excellent choice because of their proximity to students’ classes, they can also raise concerns about health and cleanliness. Dorm rooms are typically small, enclosed spaces and often shared with multiple people. This means that your college-aged child will spend most of their time in a room where personal hygiene may not be a priority for all students. In fact, in a recent study of 50 used pillows and nine used mattress pads of college students, SleepBetter.org found hundreds of thousands of bacteria, yeast, fungi, and mold

During these challenging times, indoor air quality is more important than ever. Recent studies by the Environmental Protection Agency (EPA) have found that indoor levels of harmful airborne pollutants are two to five times — and frequently more than 100 times — higher than outdoor levels. This is why an air purifier should be on every student’s list of back-to-school essentials.

Luckily, here at airpurifiers.com, we’ve researched for you. We understand that cleaning products and washing laundry only go so far, especially if your incoming freshmen have a roommate. An air purifier will not only help your college-aged freshman breathe healthier, cleaner air but also help improve their quality of sleep and eliminate other allergens, mold, dust, and more.
