Why air purifiers are must-buys for college students

College dorms aren’t exactly the most hygienic places, and because of their enclosed structure, the air can get stuffy. If you’re off to college this fall, packing an air purifier is a great way to keep your dorm’s air quality fresh and clean.

Dorm hygiene can be an afterthought in college, but an air purifier is an excellent option to maintain clean air quality even when you’re not around. The best part is it does all the work for you.

Top reasons college students should get an air purifier

Reduce pollutants

An air purifier’s primary function is to reduce pollutants. Although you might not be able to tell, your college dorm is primed for a buildup of concentrated contaminants that can originate from smoke, cooking, dust, pet dander, residue from cleaning products and mold. An air purifier can absorb up to 50% of airborne particles and ventilates a room with clean air.

Help prevent health conditions

If the air quality in your dorm is poor, you may get sick with a cough or cold more often than you’d like. Polluted air can also aggravate existing health conditions, such as asthma, and cause bronchitis and other lung conditions if left unchecked. Breathing in harmful dust particles and other contaminants is often unnoticeable since they’re too small to see, but doing so for even a few hours can take a toll on your health.

Cold climate and ventilation

Naturally, the best way to improve the ventilation in your dorm is to open a window. However, if you’re going away to college in a place where the winters are cold and snowy, it can be impractical. Instead of freezing up your room and potentially letting rain or snow get in, you can use an air purifier to maintain good air quality and ventilation.


Q. Are air purifiers safe?

A. Most air purifiers are safe as long as they’re functioning correctly. But steer clear of ozone-generating air purifiers, as it’s a purifying gas that can be harmful to yourself and other living organisms, including pets and plants.

Q. Are air purifiers effective at reducing the spread of colds and other viruses, such as COVID-19?

A. Having well-ventilated areas with proper air circulation can help reduce the spread of germs and viruses. However, since most dorms have poor air circulation, air purifiers can help because most absorb airborne droplets and contaminants.

Q. Can I leave my air purifier on 24 hours a day?

A. Generally, it’s safe to keep your air purifier running at all times, as most are designed to do so since it’s the best way to ensure the highest air quality possible. Additionally, most have a sleep mode function for quiet nighttime operation.
