7 Best air purifier for dorm room 2023

Good health is the key to success, especially during the college years. You need to be in good mental and physical health to perform well in your studies. In this regard, a fresh and healthy atmosphere in your dorm is the key ingredient. Scientifically, a fresh dorm room can help you focus on your studies and absorb more knowledge. Therefore, in this article, I will discuss the best air purifier options for dorms in 2021.

Why do you need an air purifier in your dorm?

Dorm rooms are considered one of the best breeding grounds for mold and debris. Most dormitories have little to no ventilation and a shared bathroom. Moreover, you constantly have visitors like friends, mutual friends, and friends of friends. These visitors bring some microscopic friends as well which can cause severe health issues.

Similarly, dorms provide the perfect environment for germs, bacteria, and allergens due to the lack of proper ventilation. The enclosed space usually contains a higher moisture content than outdoor, especially in rooms with an attached washroom. You don’t have the time and energy to clean your dorm regularly. As a result, resident students require a machine that can clean the air in their room without disturbing their schedule. Therefore, an air purifier is the best investment that you can make to improve your living space and keep it clean.

Air quality in dorm rooms:

According to EPA, the air quality in college dorms and other enclosed spaces is as polluted as Petri bacterial dishes. Most dorms don’t have a regular cleanliness system, and the scheduled weekly cleaning is not thorough as well. Therefore, students are required to ensure cleanliness in their rooms themselves.

Most dorms are renovated every session, so students are exposed to paint fumes, VOCs, and CO. As time passes, the rooms become breeding grounds for molds, mycotoxins, dust mites, and other pollutants. The busy schedule, lack of sleep, and proper nutrition weaken the immune system of college students. In short, college students are more susceptible to airborne diseases than other people.

Which air purifier is best for small dorm rooms?

The market is full of different air purifier models. Every type of air purifier is suitable for a different environments. For instance, high-end large air purifiers are suitable for offices and commercial spaces. Similarly, the medium-ranged air purifier is suitable for home users with 3-5 people in the house. Usually, dorm rooms have a small area, and each room accommodates 2-3 students in one room. As students don’t have a hefty budget for such luxurious appliances, only standard or battery air purifiers are suitable for them.

The first thing you need to consider in an air purifier is why you need them. For example, dorms are full of dirt, dust mites, mold, and viruses. Therefore, you just need an air purifier that comes with a standard H-13 HEPA filter and an optional air sanitization ultraviolet bulb. Secondly, the coverage area plays an important role in your selection as well. College dorms are between 180 sq. ft to 300 sq. ft. So, any air purifier that provides such coverage is more than enough, i.e., you don’t need a high-end device with an expensive price tag.

Last but not least, the build quality of your air purifier determines whether it will last the whole four years or not. College dorms are busy places with constant visitors and indoor sports. Therefore, you need either a sturdy air purifier or a small air purifier that hides from plain sight. As a result, the device will resist the impact damage or won’t be visible for a direct hit.
