When you are looking for an essential oil diffuser for your car or other vehicle, check for battery operated units reviewed right here! Some will have an adapter for the cigarette lighter or charging port, and some will include an adapter to plug into the wall—that’s a great combination diffuser! Simply add your 100% pure essential oils to the water, plug in, and turn the switch on.
1. CarZen Ultrasonic Essential Oil Diffuser for the Car
The CarZen ultrasonic cool-mist diffuser/humidifier combination is the perfect companion for your car or any vehicle. The colors available are blue, pink, green, and purple. Plug in the small unit that uses 100% pure essential oils (not included) to make your car smell and feel good providing you with therapeutic benefits as well. It will also purify the air removing lint, dust, pollen, and other allergens.
The unit rotates 180-degrees to put the mist where you want it and not in your face. The water tank holds 50mL (1.70 ounces) of water—use your water bottle to add distilled water and be off on your trip to work or wherever you need to go. The unit will operate for 2 hours continually on the water supply and shuts off automatically when the water is almost gone.
Add a bit of moisture and fragrance when the heater is running in the winter making the car dry, or in dry climates with the air conditioner on. As you are aware, humidity relieves dry chapped lips and hands, dry cough, as well as nasal and sinus congestion and elimination of viruses and bacteria. With the essential oils, you will improve your mood, and concentration, removing tension and anxiety. Be sure to use only water-soluble 100% pure essential oils. Do not use resin types or greasy, heavy oils that will clog the unit. Do not add carrier oils that are fatty.
When you notice the mist becoming thinner and lighter, replace the sponge included in your box. When you do need to clean the unit, use a cotton swab and rubbing alcohol or clear distilled vinegar to remove lime scale and mineral deposits especially on the top of the atomizing plate gently. You do not want to damage this plate.
Before putting into your car, unscrew the cap, and pour the preferred distilled or purified water in. Tap water causes mineral built up that has to be cleaned. Screw the cap back on, plug into the charging or cigarette lighter port, and enjoy your trip. Select whether you want it to diffuse with oils or moisture with only water. When you turn off the car, unplug the unit to not drain the battery. When storing the unit, take it in the house, empty the water tank, and put in a dry cool place. Never let water and/or oils sit in the unit—it will grow mold.
The dimensions are 6.46-inches tall x 2.5-inches wide at the top. It plugs into the 12-Volt D/C charger port. There is no 110/120-Volt adapter for plugging into a house outlet. The touch switch is above the logo CarZen.
You will receive in the box the diffuser/humidifier unit, an extra sponge, a User’s Manual and a 100% satisfaction guaranteed Warranty.
2. Arospa Electric Car/Indoor Diffuser/Humidifier
The Arospa is shaped like a bottle or tall cup and fits right into your truck, SUV, or car’s cup holder securely. Being an ultrasonic vibrating cool-mist unit, it uses no filters or wicks. Select from a white base with purple, black, or green to match your car or your favorite idea of color coordination. It is also used for a humidifier and air purifier. Use it without 100% pure essential oils (not included) for a bit of moisture for cold days or dry climates. The purifier will remove dust mites, spores, allergens, and dust.
Add your favorite essential oils to the water, and turn it on. Do not use ‘hot’ essential oils such as cinnamon, cloves, and others. Distilled or purified water is the best to use to eliminate lime scale and mineral deposits from tap water. Use it when traveling in your hotel room for a nice aroma. Alternatively, put it in your massage or physical therapy studio. Anywhere you want a diffuser, this unit will go.
The unit has 2 UL listed Ultrasnmit® power cords: You will have 1 for the 12-Volt D/C car adapter and a standard plug-in adapter for 110/120-Volts in the USA for your home, office, Yoga studio, spa, or hair salon.
The car cord is 2.25-feet long and the 110/120-Volt cord is 6-feet long. The unit is 6-inches tall and 2.5-inches around weighing less than 1 pound.
Use your favorite oils in the car, but not too much, because it is a small area. The mist comes out of the center top to provide you with aroma and therapeutic benefits. You have several features from which to choose. Set it for a low or high mist with 20-seconds on then off, or set it for interval misting, as you prefer. The unit will shut off when it’s out of water automatically. It is made of a durable plastic and has no materials that will rust. There are no toxins. The mist will last 3.5 hours on the low mist setting with intervals, 2 hours on the high-mist setting when you set the interval pauses for misting. It will also last 1.7-hours in low mist and 2 hours in the high-mist mode without the interval pausing. So, that means if you run it non-stop without pausing, it will use oils faster.
In the box, you will get the diffuser/humidifier combo and a User’s Manual. The return policy is 30 days from date of purchase in the original packaging, so keep all the boxes and packing material and all receipts for your purchase. After 30-days, there is no refund or exchange.
