The Best Portable Vaporizers

A vaporizer, also called a humidifier, is a device that adds moisture and humidity to a room. (Are you looking for an appliance that removes excess humidity from the room? That’s a dehumidifier–and we have a list of the best dehumidifiers, too.) If you have dry skin, irritated eyes, or a sore throat in the absence of any other signs of illness, you might simply be having trouble with the lack of humidity in a room. This is particularly true if you live in a dry climate or if you run your heat or air conditioning instead of having the windows open. More humidity in the air can also help keep you comfortable if you have a cold, the flu, or another respiratory illness.

You can set up a humidifier in your home (and here’s a list of the best ones we’ve found), but what about if you want to use it in the car, at your office, or while traveling? In this case, a portable vaporizer might be the device you need. We have looked at dozens of portable vaporizers so we could give you a list of the best ones. We looked at various types and considered their features as well as product reviews.

Best Portable Vaporizer Overall: TaoTronics Cool Mist Ultrasonic Humidifier

The TaoTronics Cool Mist Ultrasonic Humidifier earned a spot at the very top of our list of the best portable vaporizers. This is a small, compact vaporizer that won’t disrupt your sleep, thanks to its quiet operation. It runs at just over 30 decibels, which is quieter than fans and white noise machines. Because it is a BPA-free cool mist machine, it is safe to use in the nursery and a child’s room as long as you clean it properly (and it’s easy to clean, because it’s small and lightweight).

There is a dial knob that allows you to adjust how much mist is coming out at one time. It will shut off automatically if the water level is low, if you pick it up, or if it gets knocked over. This is a nice, safe portable humidifier that you might consider using on a daily basis or if someone in your family gets a cold or suffers from allergies, as it will ease congestion and keep the nose and throat well-hydrated.

Who Should Buy a Portable Vaporizer

Most people should probably have a humidifier of some sort in their homes. These can help you get a better night’s sleep when you’re sick with a cold or another respiratory illness because they keep your mucus membranes moist and can reduce nasal congestion and coughing. They’re also great to have on hand when you have a baby or small child. Dry skin, dry lips, and irritated eyes are signs that you might not be tolerating climate-controlled air well, so a vaporizer can help.

Getting a portable unit allows you to take it with you wherever you go. If you live or will be visiting a dry climate, you might even want one in the car for long road trips. You can take it to a hotel or when visiting friends overnight, or set it up in your office at work if the building tends to be arid. There’s no reason to suffer from air that is uncomfortably dry when you have a portable humidifier that you can simply put in your bag.

Important Features to Consider

When looking at portable vaporizers, there are a few features you will want to consider looking for. Here are some things to keep in mind as you make your purchase.

  • Cool vs. warm mist. Some vaporizers use warm mist, while others use cool mist. In general, cool mist is safer if you will be moving it around or if you have children who will be in the room with you. Warm mist humidifiers, though, allow for more humidity in the air.
  • Water tank vs. water bottle. Some portable vaporizers have a built-in water tank, which you fill with distilled water. Others fit into a water bottle, which you also fill with distilled water. The type that you use with a water bottle is usually smaller and easier to fit into your luggage or purse.
  • Power supply. Some plug into the wall outlet, some have batteries, and some will plug into a USB outlet. And, of course, some have various combinations of these options. Think about where you will be using your vaporizer and decide which type of power supply you’ll need.

Frequently Asked Questions

Are portable vaporizers safe?

In general, yes. There are a few things to watch out for, though. The first is the risk of burns from warm mist humidifiers. This is mainly a problem if you have young children or pets in the room who might knock it over. Cool mist humidifiers also have potential safety issues, though: You need to be sure you’re cleaning it properly, otherwise, it could grow mold or bacteria. Using chemicals and cleaners in your vaporizer can also put those chemicals right into the air, too. Be sure to clean your humidifier with white vinegar at least weekly, as this is not dangerous if it gets in the air and it will do a good job inhibiting mold growth.

Is it good to sleep with a humidifier?

Yes, you can sleep with a humidifier. It can help ease nasal congestion and dry coughs if you have a cold or allergies. It can also make you more comfortable if you tend to develop a dry mouth or dry skin. A portable humidifier might be able to hold enough water to last through the night; otherwise, it should have an automatic shutoff. Also, be sure to clean your machine regularly so it does not grow mold.

Can you use tap water in a humidifier?

No, you should use distilled water or demineralized water in a vaporizer or humidifier. That is because impurities in the tap or even regular bottled water can become aerosolized and cause breathing difficulties in some people. Read the manual of the vaporizer you are using to find out exactly what type of water is recommended, and talk to your doctor if you are not sure which is right for you.

Do portable vaporizers cause mold?

If you are not cleaning your vaporizer regularly, then yes, it can develop mold and deliver those mold spores into the air. It is very important to maintain your humidifier by washing the water receptacle without chemicals. White vinegar soaks are safe and effective. Follow the manufacturer’s instructions to ensure proper cleaning without damaging the unit.
