How to stay healthy when you live in a dorm – Dorm Air Purifiers

Air Purifier For Dorm Rooms

Imagine you're in a small dorm room with three other people. The first one who gets sick is probably going to spread it to the others. But what if you could practically immunize yourself against germs? An air purifier for dorm rooms is a good place to start.

Dorm rooms are notorious for spreading germs and causing sickness. A simple cold or flu can wreak havoc on a college student's life because of the lack of privacy, let alone a place to sleep when you're sick. An air purifier for dorm rooms helps eliminate those germs in the air that cause sickness and keep them away.


How Can Air Purifiers Help Me?

An air purifier for dorm rooms helps improve your environment so you're less likely to get sick when you live in close quarters with others. They help remove particles from the air that can cause respiratory illnesses like asthma, common colds, sinus infections, and more. They help achieve this feat by blocking UV rays, distributing heated air, and filtering particles from the air.

Naturally, an air purifier for dorm rooms helps you feel healthier. But they can actually help you feel better if your air is contaminated with bacteria and viruses caused by sickness. When you're exposed to those things repeatedly, your immune system becomes weakened and you become susceptible to more serious diseases.

An air purifier for dorm rooms acts as a shield against these diseases by cleaning the air in your dorm room of harmful germs. It gives your immune system a break between bouts of sickness so it can bounce back stronger than before.

Why You Need An Air Purifier For Dorm Rooms

The reason you need one is obvious. Your room mates are going to get sick, and you can't very well be sick all the time. The only way to keep yourself healthy in this scenario is to keep your dorm room clean and germ-free. It's going to be hard enough dealing with three cases of the common cold, but four?

Keep in mind that two of those people might not even have any colds, they could just be spreading germs around. This means you have that many less excuses for being sick through no fault of your own!

Some air purifiers for dorm rooms can even help prevent sickness by removing particulates in the air that airborne organisms breathe in and use for food.

Are college dorms clean?

Air purifiers for dorm rooms are also great stress relievers. Most people hate being sick, and every time you think about that awful cough or the runny nose, you're going to have a bad day. Having an air purifier for dorm rooms can make you feel better when you can't sleep or when your roommates keep getting sick.

It filters and distributes the purified air throughout the room so it's cleaner than in the rest of the house.

The purifiers are so quiet and unobtrusive you can keep them on 24/7 without worrying about them distracting you or your roommates.

Are air purifiers allowed in dorms?

Yes. Air purifiers for dorm rooms are allowed in most public housing areas. The only things that get in the way are mold and mildew, and they're not very common.

Should you bring a air purifiers to college?

If you plan on living in a dorm while you're at college, then I would definitely recommend that you bring along an air purifier for dorm rooms. College is a time when everyone needs to be on top of their health, and it's practically impossible to stay healthy while working double or triple shifts in the dining hall.

The air in a dorm room is especially prone to infection because of the lack of ventilation. You shouldn't have to worry about your immune system being destroyed every time you're exposed to something as simple as a cold.

Are Air Purifiers For Dorm Rooms Worth It?

Yes, they definitely are worth it. Most colleges try to save money in the dorms by cutting corners and keeping the temperature of the hallways and bathrooms lower than they should be. There's a reason students in dorms are always sick, so getting an air purifier for dorm rooms is essential to staying healthy.

Protect yourself from germs and get some rest by getting one of these nifty devices! You'll have more time to study, or focus on your schoolwork because you won't be sick as often.

How can I improve air quality in my dorm room?

There are a few things you can do in addition to using an air purifier. One, keep your windows closed to keep the air circulating and fresh. Two, wash your bedding often enough that the dust that has settled during the night isn't present when you tumble into bed. Three, invest in some good sheets and pillows, and remove those dirty ones and wash them or replace them often.

Do air purifiers help with stuffy rooms?

Yes, they can help with stuffy rooms. They help circulate the air and they can help you sleep better at night. Some people have allergies and their air is affected, so an air purifier for dorm rooms can help them sleep better.

Inhale the fresh air and absorb the oxygen in your room. It's very very important to have enough oxygen in your body. When you're exposed to bacteria and viruses every day (which can happen in college), the immune system becomes weak. That means it's next to impossible to fight off some of those diseases.

However, when you breathe in clean air that doesn't have germs floating around it, your system will be better able to fight off these germs as well as a cold or flu.

Which Features To Look For In An Air Purifier

There are a few features you might want to put some thought into when choosing your air purifier.

Coverage And Cost per Square Foot

This is where you need to be careful. There are certain air purifiers that cover only a few feet, so it's important to know what else is around them. You obviously don't want some sort of smell coming from your air purifier when other people can smell it too.

Distance and size vary between models and brands, but the most common are from 1 square foot to about 15 square feet per unit. If you want a machine that covers your entire sleeping quarters, then consider paying top dollar for something more effective than models that only cover a few feet at a time.

How To Set Up An Air Purifier For Dorm Rooms

Setting one of these up is simple, but you need to know the basics of setting it up before you buy it. There are three basic types of air purifiers for dorm rooms: UV-C, HEPA, and ionic. Some air purifiers for dorm rooms use more than one type together to provide the best results. They all work differently and have different strengths, so understanding what each can do will help you make an informed decision on what works best in your situation..

Air Purification Method

The first thing to look at is the air purification method. Most models use some sort of filtration process, which can be activated or controlled by the operator. This filter needs to be changed out when it becomes dirty, so keep this in mind when you're on a budget.

Here are some of the different types of air purifiers for dorm rooms:


These air purifiers use a high-efficiency particulate air (HEPA) filter. When I first learned of these, I was surprised how big they are! HEPA filters are the best because they don't let any particles go through the filter, and they only let the good stuff through. You can tell when this filter has become dirty and needs to be changed out by what happens when you change it out.

In some models, the HEPA filter comes with a replaceable pre-filter. This pre-filter sits out of the way in a separate package and only goes into the air purifier when you are using it. When you turn this pre-filter on and off, you can see the particles coming out of that part of the machine get smaller and smaller.

These can be quite pricey if you need one that covers a large area, but if you just want something decent to help with some of those allergies like a pollen allergy or sick room syndrome, then you may want to consider this type.

Electrostatic Filter

This type is by far the best when it comes to getting rid of particulates. They are very cheap and long lasting, and they clean better than any other type of filter for dorm rooms. If you want something that covers a large area, then you might want to look at this kind even if it's not HEPA because in terms of getting rid of particles, these are the best.

The only downside is that these filters can be difficult to clean. You should see some sort of indicator light when it needs more cleaning, but in some models it might take longer for this to come on than others.

Activated Carbon Filter

This is probably the most common type of filter to use in your air purifier. When they are new, these filters do a great job of removing odors and other particles. Unfortunately, once it has become dirty, these filters can become ineffective and you'll need to replace the filter.

The good news is that this type of filter is cheap to buy and lasts longer than some of the others.

Air Flow And Velocity Settings

This is important for helping with your allergies. You should try and look at what you can do to increase the air flow because it makes a big difference in how much clean air you can get into the space. Do you need something that is totally silent? Not always!

You might want to get one that works quietly and still works effectively. If you're able to get a model with three different settings, then this would be great too because it gives you more options based on your needs instead of being forced to choose between "on" or "off".

Are They Effective For Dorm Rooms?

The best air purifiers for dorm rooms are those that provide the most effective cleaning and airflow. If you want to get rid of particles, then you need something that can kill germs so that you don't get sick.


Allergens are very common in dorm rooms, particularly those that are close or right next to a cafeteria or other eating area, so you need to do something about this if you're someone who is sensitive. Many of these allergies come from pet dander and dust mites, both of which are in your bed covers and pillows.

Pet dander is found on bed covers and can be transferred by sitting on your bed. It might not be visible, but it's still there. In addition to that, dust mites shed dead skin cells all the time and they prefer the comfort of your warm bedding.


Pollen is also a very common allergy that occurs during the spring and summertime. Certain people are highly susceptible to pollen, so you definitely want to get something in your dorm room that can help with this.

Dust Mites

These are very common in dorm rooms because many students use their bedding and pillows from home. This is one of the reasons why you need to use an air purifier in your dorm room, and you'll want something that can help with these.

There are different types of filters, but the best ones to go for are air purifiers for dorm rooms that can kill germs and other particles.


Bacteria is one of the most common types of allergens that cause allergies in dorm rooms. It's also found on roommate's clothing and bedding, so you need to take care of it. Having an air purifier in your dorm room is your best option for getting rid of this type of allergen, particularly if you do not want to move rooms.


Mold is another source of allergen that occurs in the air. If you remove it, you can greatly reduce your chances of getting sick. You need to be careful though, because some mold spores are more dangerous than others. It's best to get a filter that is able to kill bacteria and mold spores at the same time and has an indicator light when it needs more cleaning.


If you smoke or have someone in your room who smokes, then you need to find an air purifier that will help with this. In some cases, you may not be able to get rid of the smoke completely, but you can reduce it significantly with the right filtering system.

Better Health Overall

Many of the best air purifiers for dorm rooms will do more than just filter out a few particles of dust or smoke. They will also be able to kill germs and mold spores, which makes them very effective at helping you fight off infections.

This means that if you can find one that covers other needs that aren't just bacteria or air quality, then it could be a great investment for your dorm room.


Air purifiers are not that expensive, and if you're someone who likes to stay in your dorm room and just study, then it's a great idea to install one of these. If you have a roommate who smokes, then having one is absolutely essential because it will help reduce the amount of smoke that enters your breathing zone.

They can also be great for helping with some allergies like pollen or pet dander. Finding the right dorm room air purifier for you can help to make your dorm life a lot easier and more comfortable.

Other Questions

Why is my dorm room so dusty?

Some people have allergies and other sensitivities to dust. If you do, that's something you need to consider before you choose what type of air filter you're going to get. But for the average college student, removing excess dust is a good idea because it reduces respiratory issues.

I'm not sure why, but it's probably because the air purification system can't handle the amount of pollution that comes from a bunch of people living in such a small area for so long. This is why we suggest that you buy an air purifier for dorm rooms so that you don't have to worry about all the extra dust and pollen in your room getting into your lungs.

How often should I vacuum my dorm?

How often you vacuum your dorm depends on what's in there. Every student has different things that you need to clean out of the dorm that gets a lot of dust. For example, if your carpet has some hair in it, it needs to be vacuumed every week.

Also, if there are some large amounts of trash that get thrown out every week, we'd recommend vacuuming every week to make sure your room is clean. It's also good to keep your air purifier for dorm rooms plugged into an outlet so it can do its job and put back any dusty particles back in circulation.

My dorm doesn't have a lot of dust in it. Should I buy an air purifier for dorm rooms?

Even if your room isn't dusty, you should still buy one because there's something called dampness or "bad" air that is produced when you inhale. That can cause all kinds of bacterial infections and lung damage over time when the particles get lodged into the alveoli sacs in your lungs.
