What Are Air Purifiers For Dorm Rooms?

Air purifiers are household devices that are designed to Clean and sanitize the ambient Air within the room that they operate in.

To do so, they employ a number of different technologies, the most common being physical filter media, but increasingly so, more Hi-Tech varieties are appearing on the market such as electrostatic precipitators and purifiers using UV-C light.

Some purifiers take advantage of activated carbon, sometimes known as activated charcoal, in conjunction with other purifying technology to reduce odors caused by cooking, smoking, pets, chemicals, VOCs, and other pollutants.

While there are no purpose-built purifiers for dorm rooms, the most appropriate types are going to be budget-friendly units capable of dealing with allergens, dust, and odors.

What Are The Different Types Of Purifiers For Dorm Rooms?

The most commonly found types of purifiers suitable for college dorm rooms are: 

HEPA Filtration

HEPA is widely regarded as one of the highest standards of physical media filtration available.

A true HEPA filter is capable of removing 99.97% of all particles greater than 0.3 microns in diameter from the air that passes through it.

UV Lights

Much like negative ion generators, UV lights are also usually fitted to other types of air purifiers as an additional feature.

Not all spectrums of UV light can be used for sanitizing purposes – the type of light you will find in a dorm room air purifier will be UV-C.

Because of its short wavelength, UV-C Delivers enormous amounts of energy to pathogens at a cellular level.

This burst of energy destroys certain elements of those microorganisms, which prevents them from reproducing, and eventually causing illnesses.

The UV-C light is typically directed a physical filter media and will sanitize air as it passes through.

Activated Carbon Filtration

Activated carbon is often referred to as activated charcoal because charcoal is used in the production process. the charcoal undergoes superheating and a chemical treatment which gives the carbon molecules an extremely porous structure.

This porous structure results in an enormous surface area, perfect for use in an air purifier.

As odor-causing contaminants such as VOCs pass through the activated carbon media, they are bound to its surface by the process of adsorption.

These particles are chemically bound to the charcoal filter, and because of the change to their molecular structure, odors are neutralized.

Ionizing Purifiers

Ionizing purifiers use a device called a negative ion generator to release large streams of negatively charged ions into the room.

These ions remain Airborne until they bump into a contaminant such as dust dander or pollen, and then bind to it.

The end result is that the Airborne contaminants then drop down to the floor, or some other surface, effectively removing the pollutant from the air that you’re breathing.

Negative ion generators are typically add-on features on other types of air purifiers. they can usually be turned on or off depending on whether you want to use them.

How do Air Purifiers For Dorm Rooms Work?

Air purifiers for dorm rooms are usually built with a variable speed fan.

This fan is used to draw in air from the room, pass it through, or over the purifying media, whether that’s a HEPA filter, UV light, activated carbon, or a combination of all of these technologies.

Once the air has been cleaned by the purifying section of the unit, it is returned to circulation within the room, again, by the use of a fan.

The longer the air purifier is allowed to run, the more cleaning cycles it will complete, resulting in a cleaner environment, free from dust, pollen, and odors.

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

While many dorm room air purifiers take advantage of the same technologies, some are inherently better than others owing to these functions and features.

To find the best air purifier for your dorm room, be on the lookout for the below:

High Particle Removal Percentage

If you’re going to the trouble of investing in an air purifier for your dorm room, you will definitely want to look for one that filters out the maximum amount of Airborne pollutants and contaminants.

Those with HEPA filters are a great choice due to the fact that they will remove 99.97% of particles greater than 0.3 microns in diameter.

Quiet Operation

As most dorm rooms are shared spaces, it’s a good idea to look for an air purifier with quiet operation. Especially if it’s not a joint purchase between you and your roommate, a noisy air purifier will be a fairly quick way of getting on each other’s nerves!

Construction Quality

Here we are looking for a blend between good build quality and affordable prices. Yes, there are air purifiers that cost several hundred dollars that would be perfect for a dorm room-sized application, but tuition is expensive enough without worrying about spending so much on a purifier.

You should look for an air purifier that doesn’t squeak, knock, or rattle when it’s picked up, and especially when the fans are running.

Ongoing Maintenance

Investing in an air purifier for a college dorm room goes beyond purchasing it, turning it on, and forgetting about it. 

The vast majority of air purifiers require frequent filter changes and often require that you physically clean pre-filters and other cloth elements.

You should be looking for air purifiers with readily available, low priced replacement filters, and if the purifier has a filter change reminder, even better!
