Seasoned travelers know how to conduct the standard hotel room check. Are there clean towels and sheets? Is the coffee pot prepped and ready to go? Those who travel a lot are also familiar with the most common hotel horror stories and the accompanying pictures often found on well-known hotel review sites, some of which are enough to make you shudder.

Best Travel-Size Air Purifiers

One issue that’s frequently overlooked due to its lack of in-your-face visibility is the air quality in a hotel room. For the average traveler, air quality doesn’t even cross the mind. However, for those who suffer from asthma or allergies, air quality is just as important away from home as it is in the home.

Top 5 Travel-Size Air Purifiers

5. Mooka Air Purifier Review

This compact air purifier from Mooka is sized just right for crowded suitcases. The 3.2-pound purifier is only 7.5 inches tall and 6.9 inches in diameter. Once you get to your destination, you can put it on your bedside table or desk for close-range air purification. It’s even equipped with an automatic nightlight that puts out a soft, blue glow.

Mooka Air Purifier Review

Inside of the white, cylindrical purifier, there are three filters that protect you from airborne contaminants. It contains a true-HEPA filter that traps allergens and germs, a pre-filter that keeps large particles from clogging the purifier and an activated carbon filter to destroy stale, unpleasant odors in your hotel room.

Mooka’s choice to wrap the intake completely around the bottom of the purifier maximizes the device’s airflow rate, which tops out at 20 cubic feet per minute. Despite the surprising amount of power the fan produces, the air purifier never climbs above 60 decibels. If you want to change the fan speed, the power button on top of the purifier makes it easy to select from among two strengths.

4. DHS Desktop Air Purifier Review

Like the Mooka purifier at our number five spot, this air purifier by DHS is meant for placement on nightstands or tabletops. Weighing 1.14 pounds and measuring 7.68 inches tall, the purifier’s diameter of 4.92 inches means it doesn’t take up much space. Made to look like wood, this mini-cylinder has a stunning Gabon ebony finish.

To keep the 108 square feet of air around it clean and fresh, the purifier has a true-HEPA filter with an activated carbon layer, allowing the air purifier to trap irritants and eliminate their accompanying smells. The device even has a built-in ionizer that releases five million particle-grabbing negative ions in the air.

As soon as you press the power button, the 32-decibel fan starts circulating air and the ionizer begins releasing anions. Simultaneously, the blue ring on the purifier’s top casts a relaxing light toward the ceiling, helping you rest easier at night. If you press the button twice, the air purifier goes into sleep mode and turns itself off after 8 hours of continuous operation.

3. AirTamer A302 – World’s Best Portable Travel Air Purifier Review

Versatility is always a plus in our book, and that’s just what you get with Filter Stream’s AirTamer A302. Weighing a mere 1.76 ounces, this 1.3-inch by 3.1-inch tall wearable air purifier can be used in three different ways. You can put it around your neck by using the adjustable lanyard, hook it to your shirt with the built-in clip or stand it upright on a table.

AirTamer A302

Even though the air purifier is small, it’s quite powerful. It relies solely on ionization, releasing negative ions within a 3-foot radius to prevent harmful pollutants from reaching your airways. Thanks to its efficiency, the purifier reduces 98.9 percent of smoke particles in as little as 10 minutes.

Since there are no filters, the cost to maintain this purifier is almost non-existent – It only requires two inexpensive lithium-ion batteries, which last 7 days if the purifier runs continuously. To turn it on, simply slide the power switch, and the power indicator light will illuminate. As a bonus, you get a silver-toned metal carrying case, which is great to have for traveling or storage.

2. AirTamer A310 Personal Rechargeable and Portable Air Purifier Review

If you don’t want to buy disposable batteries, the AirTamer A310 operates off two rechargeable lithium-ion batteries. On a full charge, the device provides you with 150 hours’ worth of protection from airborne particles before it needs to recharge for 2 to 3 hours. For your convenience, Filter Stream includes a USB cable with the A310W.

AirTamer A310 Personal Rechargeable and Portable Air Purifier Review

Once you turn it on, the purifier emits two million anions in the air around you up to a 3-foot radius. There are no filters with which to contend, cutting down on maintenance expenses. Since this air purifier doesn’t require a fan to work, it won’t produce any sounds that will disturb you or your fellow passengers.

You don’t have to worry about this powerful air purifier taking up much room in your bag. It’s only 3.5 inches tall and 1.65 inches wide. You can wear it around your neck or place it on a table. When not in use, the 0.11-pound purifier fits snugly in its accompanying metal storage case.

1. GermGuardian GG1000 Pluggable UV-C Sanitizer and Deodorizer Review

Like the two AirTamer purifiers on our list, there are no filters in the GermGuardian GG1000. However, this air purifier contains a 3.5-watt ultraviolet-C light bulb that lasts for 5,000 hours. Thanks to the use of UV-C technology, this purifier breaks down bacteria and viruses at the cellular level by drawing air into the inlet via an internal fan.

All you have to do to reap the benefits that this air purifier offers is to plug the device into an electrical outlet. To make sure you can use it anywhere, Guardian Technologies designed the purifier to fit into a socket vertically, horizontally and upside down.

Despite its ability to destroy 99.9 percent of bacteria, mold spores, and viruses, this concave cylinder of a purifier is only 7.5 inches tall and 3.2 inches in diameter at its widest point. Its tiny size and low weight of 1 pound make it ideal for use in hotel rooms while on vacation and home in small spaces like guest bathrooms.

Travel-Size Air Purifier Buying Guide

Whether you’re headed to Hawaii for the vacation of a lifetime or Denver for a business trip, you don’t want a nasty cold putting a damper on your plans. This is why countless people rely on travel-size air purifiers to reduce their chances of catching an airborne-germ related illness. Before you start buying travel necessities and packing your bag, here are some key features you need to know about these personal purifiers.

Best Travel Air Purifiers

Travel Air Purifier Size

You have to make the most of the space in your suitcase, so you don’t want any item you pack to take up a ton of room or weigh down your luggage. It’s best to stick with a travel-size air purifier that’s less than 1 foot tall and wide. One that weighs a few pounds is fine unless it’s designed to hang around your neck. In that case, stick with a purifier that is 1 pound or less.

Travel Air Purifier Airflow

Travel-size air purifiers are limited to cleaning the air within a small radius of usually several feet. To get the maximum benefit of their purification power, look for a model with a decent airflow rate – 15 or 20 cubic feet per minute is a safe bet.

If the manufacturer doesn’t list the rate or the purifier doesn’t have a fan, you can get an idea of how well it circulates the air by examining the air purifier’s intake and outlet. Simply put, the larger the intake and outlet, the better.

Travel Air Purifier Noise

You don’t want a noisy air purifier that will disturb your sleep, especially if you’re suffering from jet lag. During travel, you don’t want to bother anyone else. Don’t make the mistake of thinking an effective air purifier will be loud.

Travel-Size Air Purifiers

Most travel-size air purifiers make little to no noise depending on their internal components. A sound output of 60 decibels is equivalent to the sound made during a normal conversation, so make sure the purifier you choose doesn’t get louder than that.

Travel Air Purifier Purification System

Typically, travel-size air purifiers are equipped with one of three purification technologies – a filter, an ionizer or an ultraviolet-C light bulb. All three of these technologies are well-adept at purifying the air.

Those with a filter or UV-C bulb offer dependable performance as long as the filter is changed on a regular basis and the bulb is replaced when necessary. Air purifiers that release negative ions have no parts that must be changed as part of their routine maintenance; however, you may need to wipe down the brush occasionally.

Compact Air Purifiers

Travel Air Purifier Power Supply

Like the purification technologies, the way travel-size air purifiers are powered also varies. Some models plug directly into the wall. The benefit to pluggable purifiers is that you don’t have to pack or purchase batteries, but you won’t be able to use them on a plan or in a car.

Many operate off disposable or rechargeable batteries. Disposable batteries only cost a few bucks, so they won’t make a dent in your wallet. Rechargeable batteries have no associated cost, but you need to remember to bring a charger cord. Luckily, most rechargeable air purifiers come with a USB cable. Make sure to adhere to the Transportation Security Administration and the airline’s rules on batteries if your travel plans involve a flight.

What Factors Contribute to a Hotel Room’s Air Quality?

Hotel rooms are a smorgasbord of allergens and irritants. From the HVAC system to the carpet, there may be mold and dust mites ready and waiting to rear their ugly heads. Before you book a stay at your hotel of choice, you should be aware of the major air quality offenders you may come across.

One common air irritant found in hotel rooms is cigarette smoke. Although no-smoking rooms are offered at almost every hotel in the United States, this is not always the case in other countries. Even rooms that are marked non-smoking may not be free of cigarette odor and toxins. Guests all too often light up in what are supposed to be cigarette-free hotel rooms, and hotels typically don’t take the proper steps to eliminate the chemicals left behind.

While on the subject of chemicals, you may be subject to off-gassing by dangerous VOCs, or volatile organic compounds from the carpet in your hotel room. Although most off-gassing occurs within the first few months of carpet installation, this process can last for 5 years or longer. Plus, carpets harbor untold amounts of dust mites, which are stirred up when housekeeping vacuums. Since hotels prefer to use dark carpet to hide unsightly stains, it’s difficult to determine the carpet’s level of cleanliness.
Although you can’t see them, the cleaning products used by hotel staff are also VOC offenders. Hotels usually purchase and use harsh cleaning products in an effort to give rooms that just-clean scent. Since housekeeping is usually in a hurry to get through the rooms on their to-do list, these chemicals may not be mixed correctly, or they may not be fully rinsed off the surface on which they are used.
We’ve all read the news stories about the shortcuts taken by housekeeping when it comes to cleaning guest rooms. Although any decent hotel will change the bed sheets per requests and before any guest checks in, the same pillowcases and comforters are often reused from one guest to the next without being laundered. Therefore, people often sleep on beds teeming with dust mites, hair, and dead skin flakes, all of which find their way in the air when the hotel maid gives the duvet cover a good shake.
The HVAC system is perhaps the most overlooked area of a hotel room, but it plays a crucial role in the room’s air quality. Hotels are notorious for neglecting to change the filter in their guest rooms’ heating and air units. Signs that the room’s HVAC unit is filthy may be detectable by sight or smell. If you see black growth within the unit’s vents or smell stale, unpleasant odors when it’s running, request that the hotel cleans the unit and changes its filter right away.


One viable solution to combating the dirty air in a hotel room is using a travel-size air purifier. Unlike those meant for home or office use, travel-size air purifiers are small and fit easily inside of a suitcase. They offer close-range protection from germs, allergens, and other airborne contaminants.

Even though they are significantly smaller, travel-size air purifiers work the same as full-size ones. The fan pulls in dirty air, pushes it through the purifier’s filters and releases clean air back into the room.

You have several choices when it comes to the type of travel-size purifier you can buy. Some look like a standard air purifier, and they are sized to fit on a nightstand or desk. Others are designed to be worn around your neck, which comes in handy during long trips.

There are even some that plug directly into the wall. If you choose to use a plug-in purifier, make sure you bring the appropriate plug adapter for your destination if traveling outside of the United States.

Best Travel Air Purifiers
Every country and airline has its own rules about what is permissible to have in carry-on luggage. In the United States, the TSA, or Transportation Security Administration, has no rules against bringing an air purifier in a checked or carry-on bag. However, most major airlines prohibit the use of a personal air purifier on the plane.

While you should always check with the TSA and the airline before you depart, this means you’ll have to wait to use your air purifier when you land. Of course, if you’re traveling by bus, train or car, feel free to put your air purifier to use and stave off the germs that swarm around the close quarters of multi-person transportation.
