Attaching USB Cables

The USB cable will attach to your computer or laptop ports and other devices using ports. Put in your vehicle using the lighter plug-in running off the vehicle’s direct current (D/C) battery. You can put your diffuser on your desk top, bedroom night stand, living room table, mantel, or anywhere you want the pure essence of essential oils. Simply add your 100% pure essential oils to the water in an ultrasonic diffuser and only essential oils with no water in a nebulizer diffuser. Plug it in, and turn the switch on and set the timer and LED lights to the way you like your experience best.

Many times, driving around the city locally, we don’t want to breathe the outdoor air because it’s so polluted. Put a diffuser in your car for your road trips and adventures, crank up the radio, and enjoy the ride with a wonderful aroma.

The essential oils will rid your vehicle of doggy odors and tobacco smoke if someone still smokes these days. If you have old food wrappers in the car, the diffuser will remove those odors as well. The units will remove the same odors from your home or other environment.

What to Consider Buying a Diffuser

Do not waste your money buying an inferior essential oil diffuser. Think about features you want and like most to benefit you and your surroundings. I’ve listed some things for you to be concerned about for the price you pay and the functions of the unit.

• Water Capacity

Water Capacity is important for an ultrasonic diffuser since they use water with oils added. If you want your diffuser to hold more water, buy a larger milliliter (mL) unit also showing ounces below. For instance, a 100 mL diffuser will hold 3.38-ounces of water. The more water it holds, the more hours it will run.

• Water Type

If you want the best water to use with no clogging of the diffuser or its parts, do not use city tap water that is dissolved rock in ground water that leaves spots on dishes, scale on glass shower doors, with blue/green lime and iron gunk around faucets. Buy yourself a jug of distilled or purified water at about $1 per gallon for the best results. City tap water will put fine white mineral dust on your furniture as well.

• Square-Footage

Square-Footage is for knowing the amount of space the mist will cover. If you have a 10- x 12-foot room that is 120-square feet. Take the width and length of your space and multiply to get square feet. This will tell you if it will mist for your room size.

• Timer

Timer is good to have as a feature to run for the hours you want it to. Each diffuser tells the hours it can be set for. There are many options: 1-, 3-, 6-hours, continuously, or different configurations for the hours by the diffuser manufacturer.

• Intermittent/Continuous

Intermittent means it turns off after about 30-seconds of running and then turns back on.  This saves essential hours and will operate for a longer time.  Continuous means it will run forever until it shuts off automatically when the water is low for ultrasonic diffusers and when the oil is gone for nebulizer diffusers.

• Automatic Shut Off

Automatic Shut Off is a benefit so that when the diffuser is out of water or oils it will shut down automatically for safety. Most units today have this feature to shut off when the water or oils are low. This gives you peace of mind if you use it when sleeping.

• Whisper-Quiet

Units are now available where the fan is so quiet you will not know the diffuser is running.

• LED Lights

Almost all diffusers, especially the ultrasonic ones, have lights that cascade over the entire unit. The lights can be dim or bright, cascade through all the colors, usually 7, set to a favorite color, and can be completely turned off. Some diffusers illuminate only around the middle or at the switch buttons. Check out what you want and select the best here.

• Portable Essential Oil Diffusers for Vehicles

Use the same features as listed above. Some have both A/C cords and USB cables to run of the vehicle’s battery. The USB can also be plugged into any device with a USB port.

• Nebulizing Diffusers or Ultrasonic Diffusers

Remember that ultrasonic diffusers use water with essential oils added to the water and nebulizers do not use water using only essential oils.

All ultrasonic units are 5-in-1 diffusers because they do use water.

• Diffuser
• Small humidifier
• Air purifier using essential oils
• Night light
• Ionizer using water that is a law of nature

Nebulizers are a diffuser, a night light if they have lights, and an air purifier.
