How to get the best air purifier for dorm room? Here are the Insights!

Soon it will be time again when parents and soon-to-be college students are out buying all the supplies they will need for the school year.

One often overlooked thing is getting a air cleaner. A dorm room can be extremely dusty and polluted, so it’s essential to have a quality purifier to breathe clean air. If you can’t get much fresh air, it is only prudent to invest in a good air purifier.

In this article, we will discuss the best air purifier for dorm room and provide you with a buyer’s guide to help you choose the right one!

Why is it necessary to have an air purifier in your dorm room?

If you’re like most college students, you don’t have a lot of time to tidy up your place. There’s not always enough time to finish everything between classes, studying, and socializing.

Dorm rooms are notorious for mold spores, debris, and allergens like dust, pet dander, and pet hair. An air purifier can help care for airborne pollutants, so you don’t have to be concerned about your well-being. It’s a small investment that can significantly impact your quality of life.

So if you’re looking for something to freshen up your room and keep it that way, you might consider getting a purifier.

Quality of breathing air in dorms:

As a college student, it’s essential to be aware of the poor dorm room air quality. According to the EPA, enclosed spaces like dorms have air quality as polluted as Petri dishes. Unfortunately, most don’t have a regular cleaning system, and the weekly cleanings are often not thorough. This leaves students responsible for ensuring their own room’s cleanliness.

Generally, dorms are renovated every session, exposing residents to new pollutants like paint fumes, VOCs (volatile organic compounds), etc. Over time, as the rooms age, they become breeding grounds for molds, mycotoxins, dust mites, and other harmful particles.

Suppose you have frequent allergy symptoms; this is a poor air quality indicator and requires your immediate attention. The immune system is weakened by a busy schedule, lack of sleep, and improper nutrition. This makes them more susceptible to airborne diseases. These can spread through more than just touch; they can also be transmitted from items that have been used or touched.

Smokes and odor:

If you are a college student, I am sure you know how bad the indoor air quality is in some hostels and dorm rooms. There can be smoke from cigarettes, marijuana, and the kitchen. Moreover, other bacteria and viruses can come from unwashed clothes, leftover food, etc.

A dorm room air purifier can help remove these smells and microscopic particles from indoor air.

VOCs and Disease-causing organisms:

If you’re living in a college dorm, there’s a good chance that indoor air quality is affecting your well-being. New paint jobs, walls, and the dry-cleaned clothes of other students can emit VOCs that lead to respiratory issues.

Having a purifier to improve the quality of indoor air is essential. It will purify the air by eliminating VOCs, airborne particles, and pathogens so you can breathe more easily when studying or hanging out with friends.

What would be the best air purifier for a college dorm room, if you’re wondering? Worry no more because we have compiled an air purifier review of the top 5 picks that are budget-friendly.

What is the best air purifier for dorm room?

Are you looking for an appliance to help improve air quality in your college dorm room?

If so, there are a few things you need to consider before making your purchase.

You first need to consider why you need a dorm air purifier in the first place. College dorms can be full of dirt and dust mites. So, choosing one with a standard H-13 HEPA filter and an optional air sanitization ultraviolet bulb is vital.

Next, you need to consider the size of your dorm room. Most college dorm rooms range from 180 sq. ft to 300 sq. ft. , so you don’t need a high-end, expensive device—instead, one with a good air filter for your room size.

Finally, you need to think about the build quality. Student living spaces are busy places with lots of traffic and indoor sports. So, it is crucial to choose one that is either sturdy or small and hidden from view.

After considering these factors, the five best air purifiers for dorm rooms are as follows.

What Do You Look For In The Best Air Purifiers For Dorm Rooms?

A good air purifier should be capable of efficiently taking in and expelling air. It should be effective at removing contaminants and pollutants from the environment. You should consider the type of filter it has installed. Most air cleaners come with HEPA filters or activated carbon filters.

The following are some considerations when searching for the best air purifier for your dorm room:

Noise Level

We all know the importance of breathing clean air. Unfortunately, most dorm rooms are shared spaces. If you want to stay friends with your roomie, we must look for a quiet purifier or one with sleep mode so as not to be too loud when running.

Some mildly loud air purifiers come with white noise function that can aid in improving concentration.

Particle Removal Percentage

A decent and healthier way to get a good night’s sleep in your dorm is with an air purifier that removes the most airborne pollutants and pathogens. Filter types like carbon filters or a HEPA will remove harmful particles, which are great for eliminating allergies.

Built Quality

You can find affordable dorm room air purifiers that suit your needs without compromising quality. Air quality in dorm rooms is critical, but tuition costs make it difficult to invest too much money into one purchase!

It would help if you looked for quiet appliances and ones that don’t squeak when picked up or turn on their fans while running. These are just some examples of things you might want during this search because there are no specific “normal” noise levels regarding air cleaners.

Maintenance Requirement & Budget

Investing in a college dorm room air purifier means more than just purchasing one. You must consider how often filters need changing and ensure it’s easy for students with low cleaning skills.

I’ve found the best way is by looking out for models that offer readily available replacement filters, like those sold at your local hardware store or drugstore (though these might not always work). If there’s even an option between high-quality Pre-filter paired up nicely alongside some Post Cleaner solution, go ahead!

Clean Air Delivery Rate (CADR)

The Clean Air Delivery Rate, or CADR for short, is a score that indicates how effective an air cleaner is at filtering out different types of pollution. The higher the number – meaning more particles are caught in its filters- means better filtration and healthier living space!

AHAM’s standard requires minimum Smoke CADRs to be 100+, with separate scores against pollen & dust particles. This ensures faster cleaning times than just having one all-inclusive rating.

Air filters

Air purifiers work by trapping and removing particles from the air. Air filters are critical to an air purifier. The most common type of filters includes HEPA filters and carbon filters. A HEPA filter can remove majority of the fine dust particles and allergens. Most air purifiers usually have HEPA filters as these are preferred over others by consumers and can be used in homes as well as in hospitals, schools, offices, and other places where people spend much of their time.

HEPA filters are made from high-grade materials and are durable. They are also durable and last long. They are effective in removing dust from the air along other harmful particles. This filter is very efficient and can remove a wide range of airborne pollutants. Activated carbon filter is a material that absorbs harmful substances present in the air. When the air enters into the filter, the carbon helps it absorb the odors, fumes, gases, particles, and other contaminants.

Then the air passes through the filter again without releasing the harmful substances and is released back to the room. If you are looking for the best air purifier for your room, then make sure that it has good filtration system that includes pre-filter. A pre-filter is a layer of material that is placed between the filter and the intake of the air purifier. Pre-filters are helpful because it prevents large particles and dust from entering the main filter.

These large particles may clog the filter, which may result in an inefficient and ineffective air purification. Hence, it is important to make sure that you have a good pre-filter in your air purifier. Consider the size of the air purifier to make sure that has room size coverage. Moreover, also keep in mind that an air quality indicator can help you to know the quality of air in the room. It can tell you about the quality of air inside your house, office, and even inside the car.
