What criteria are required to determine the best air purifier for a dorm room? First, you’ll want to consider the size of the unit. Depending on the size of your room, and if you have a roommate, you might prefer a desktop air purifier rather than a floor model. Or, you may consider a fine plug-in air purifier that goes directly into the wall outlet. Traditionally, dorm rooms tend to be small. A large floor unit might be impractical because it can take up a lot of space.

Additionally, you’ll want to consider which air pollutants are an issue and find an air purifier with a filtration system that’s rated to effectively and efficiently remove those contaminants. Other features, like quiet mode or even an app-based control panel, can make your air purifier more intuitive and easier to use. There are lots of top-rated air purifiers to choose from. Keep reading our buying guide on the best air purifier for dorm rooms to learn more.

Beginner’s Guide to Dorm Room Air Purifiers

What are Dorm Room Air Purifiers

Even though you might use the search phrase “dorm air purifiers”, know that these are essentially just regular air purifiers. Just like any other interior space, dorm rooms can have poor air quality. Everything from offensive odors like old gym clothes and burnt food, and of course cigarette smoke can all make indoor air stale and unpleasant to breathe.

Add in the potential that you might have a roommate and there are plenty of contributing factors that can lead to poor air quality. For instance, lots of dust can make your dorm room unpleasant, but the good news is that there are lots of air purifiers that are perfect for dust. A good air purifier for odor can remove pollutants as well as trap odors depending on the filtration technology it uses.

Additionally, considering that you’re potentially living in a shared space, you might also want to consider investing in an air purifier with germicidal functionality to help remove harmful pathogens from the air. Typically, you can opt for an air purifier with a UV light function or an antimicrobial coating on the primary filter to aid in removing pathogens.

Dorm Room Air Purifiers vs. Air Purifiers

There is no significant difference between air purifiers designed for smaller spaces like dorm rooms and those intended for use in the home. In both scenarios, these units work similarly to help remove various pollutants to improve indoor air quality.

Just like with standard air purifiers, you can find dorm air purifiers with varying filtration methods. This includes HEPA, activated carbon, UV light, and even ionizers. The right filtration method is going to depend on the contaminants that are present in your dorm room.

And just as with air purifiers for the home, you’re going to need to focus on the CADR or clean air delivery rate score to ensure that you’re picking a unit that’s compatible with the total square footage of your dorm room.

The general recommendation is that you should pick a unit that’s rated for a room that’s slightly larger than where you plan to place your air purifier. But considering the communal nature of dorm rooms, you also need to consider the human element.

If you have a roommate, they may or may not be on board with incorporating an air purifier into the room. A floor model — while efficient — may be too big for the room. And considering that dorm rooms aren’t always spacious, a large air purifier can take away from essential floor space for other furniture.

So, one minor way that dorm room air purifiers can vary from home air purifiers is the size. If you have a roommate who refuses to give up precious floor space for a unit, you might need to settle for a less obtrusive desktop model. Size is not the only thing that matters when it comes to choosing air purifiers. How do you know what brand to choose or what the best dyson air purifier is? It can be hard to narrow down your choice.

How Dorm Room Air Purifiers Work

Dorm room air purifiers work just like traditional air purifiers. They usually feature a pre-filter and a primary filter. The pre-filter is located near the intake and helps to remove larger particles from the air, helping to extend the primary filter’s lifespan.

The air purifier relies on a fan to help draw air into the primary chamber where it is passed over the filter and additional particles are removed from the air. The cleaned air is then released back into the room through the outtake.

More importantly, you need to determine which filtration method is best for the impurities you’re trying to remove. If dust particles, smoke, and pollen are your biggest concerns, a HEPA air purifier filter is best as it can remove particles as small as 0.03 microns.

For students that want to remove stale odors and volatile organic compounds (VOCs), an activated carbon filter is the best option. However, you’ll want to ensure that the filter contains several pounds of carbon for the best results. While air purifiers with ionizers can also control odors, they don’t completely remove them from the room. This means that once the ionizer mode is deactivated, the odors may return.

To remove pathogens, you should opt for an air purifier that contains a UV light feature or has a primary filter with an antimicrobial coating. But with UV light, you’ll want to ensure that the light stays on for several minutes to ensure that pathogens are effectively destroyed.

Why Should You Buy a Dorm Room Air Purifier?

Dorms can have all kinds of odd smells. And even normal irritants like pollen and dust can accumulate and create poor indoor air quality. Considering that your dorm will be your temporary home for several months every year, creating a more comfortable environment is important.

Are Dorm Room Air Purifiers Worth Buying?

  • You Live in a New Dorm Building: New buildings mean you’ll regularly be near off-gassing items. Everything from carpeting, freshly painted walls, and even furniture can release VOCs which can reduce air quality.
  • Someone on Your Floor Smokes: Maybe your roommate isn’t a smoker. But if anyone on your floor smokes (both cigarettes or weed), that smell is inevitably going to make its way to your room.
  • You Have Allergies: Common irritants like dust, mold, and pollen all contribute to allergies. Having an air purifier can help keep those irritants to a minimum.
  • You Want to Banish Lingering Odors: Everything from gym shoes to late-night pizza runs can contribute to old odors that can make your room smell less than inviting. An air purifier with an activated carbon filter can help remove old odors.

Why Dorm Room Air Purifiers May Not Be for You

  • You Don’t Have Space for an Air Purifier: Air purifiers are great additions to improve air quality. But they can also take up quite a bit of space — especially if you want to bring a floor model into the room.
  • You and Your Roommate Can’t Agree on a Unit: Dorms can be shared living experiences. This means that you need to get your roommate to agree when you’re considering adding an air purifier to your room.
  • You Won’t Run It Consistently: Air purifiers work best when you run them continuously. If you constantly turn it on and off, it’s not going to be as effective.

How Long Will Dorm Room Air Purifiers Last?

The actual air purifier devices can last for years before you need to replace them. But the more important factor is that the filters must be replaced consistently throughout the year. This represents additional work for you, as well as a fixed cost to purchase replacement filters.

Depending on the filtration system, the cost and replacement timelines can vary. HEPA filters tend to be the most expensive to replace, costing as much as $200 for each filter. Yet, they only need to be replaced every six to 12 months.

Activated carbon filters should be replaced more frequently — every three to six months. But these filters are significantly cheaper to buy, costing no more than $50 per filter. And for best results, you should periodically wash the prefilter if your air purifier has one.

As we’ve mentioned previously, a prefilter can help to reduce the total workload your primary filter must support by removing larger airborne particles from the air before entering the main filtration chamber.

How to Choose a Dorm Room Air Purifier

There are a few factors that are of particular importance if you’re shopping for a dorm room air purifier. In particular, you’re going to want to pay attention to the size of your unit, and the filtration method that it employs. However, other factors which are important for any air purifier should also be considered.

Dorm Room Air Purifiers Key Factors to Consider1. How big is the unit?

Air purifiers come in a variety of sizes. But you’ll want to pay attention to the size considering that many dorm rooms are quite small. If you have limited floor space, the last thing you want is to create a cluttered environment where you and your roommate have to hop around an air purifier.

Alternatively, if your roommate refuses to have a floor model, you can opt for a desktop air purifier. While these aren’t useful for fully cycling through all of the air in your dorm room, they can be useful for purifying the air immediately around you. This might be a solution for someone who spends limited time in their dorm room.

2. What pollutants do you want to remove from the air?

For the best fit, you need to match your air purifier’s filtration method to the pollutants in the air. HEPA filters are best for dust, pollen, smoke particles, and mold, with the ability to remove airborne particles as small as 0.03 microns in size.

Activated carbon filters are best for removing odors and VOCs. UV light is best if you’re concerned about pathogens — as long as the light lasts for several minutes. Ionizers can help with neutralizing odors, but are not as effective as activated carbons and can also potentially create ozone as a byproduct.

3. What is the CADR rating?

You want to ensure that you pick an air purifier that’s designed to effectively move air. You should ideally look for a unit with a CADR score that’s slightly higher than what’s necessary based on the total square footage of your dorm room.

4. Is there a quiet setting?

By default, dorm rooms usually aren’t large. This means that if you pick an air purifier that’s too noisy — even in the lowest speed settings — you might find it too loud to run consistently. Ideally, look for models that feature quiet or sleep modes which means that the fan won’t emit more than around 50 decibels while in operation.

5. How frequently do the air filters need to be replaced?

Remember that the actual air purifier unit can last for long periods without needing to be replaced. But the air filters must be replaced regularly. HEPA air purifier filters must be replaced every six to 12 months while activated carbon filters must be replaced more frequently at three to six-month intervals.

6. Is the air purifier easy to use?

Even if you’re incredibly tech-savvy, you still want an appliance that doesn’t require an advanced degree in engineering to operate it. Look for easy-to-use control panels. In some cases, you can even find air purifiers that rely on smartphone apps to operate them.

Dorm Room Air Purifiers FAQs

Are air purifiers allowed in dorm rooms?

Yes, they usually are. Although, it’s always a good idea to confirm that your college or university allows them. Many schools encourage students to bring air purifiers to improve indoor air quality.

Do air purifiers help with stuffy rooms?

Yes, they can if you pick the right filtration method. Activated carbon air purifiers can help to remove not just odor-causing particles, but gases and chemicals that can contribute to stale dorm room odors. Likewise, if mold is the source of a stuffy smell, then a HEPA filter-based air purifier is a great option.

Why is it good to have a dorm room air purifier?

Considering that dorms are communal living spaces, there are more sources for odors and unhealthy air quality. A good air purifier can keep pollutants to a minimum and help reduce the risk of suffering from allergies or having respiratory conditions exacerbated.
