While they probably won’t prevent you getting sick, they can make your house smell like a spa and some scents could even help relieve stress (which, hello, we could all use some extra stress relief this year). So when we got ahold of Amazon’s Prime Day deals list and saw that a top-rated essential oil diffuser was on sale, we were jazzed. The Aromacare diffuser can hold up to 20 ounces (600 mL) of water and can run continuously for up to 18 hours. We love that it has an auto shut-off feature when it runs out of water, so you don’t have to worry about the bottom of your tank burning or overheating. It also has a warm yellow night-light feature that can be turned on and off to make your space cozy. Bonus: It also acts as a cool mist humidifier, so your room can be less arid during cold winter months. Aromacare 600ml Essential Oil Diffuser for Large Room Amazon Over 1,200 reviewers have rated this essential oil diffuser an average of 4.3 stars. They love its “attractive wood grain look” and say it’s “whisper quiet when running.” Another reviewer says, “I have been diffusing oils in our home every day for two years, and this is my new FAVORITE diffuser! This large-capacity diffuser is great for open spaces or large areas. I can smell my oils all throughout my first floor when I have it on the ‘high’ output setting, and it lasts for hours on end!” If the glowing reviews aren’t enough to get you to pull the trigger, maybe Amazon’s Prime Day Lightning Deal will sweeten the pot. Today only, Aromacare's essential oil diffuser will be 27% off (originally $32.99, it will be lowered to $23.99). But hurry, once this deal is over, you won't be able to claim it. If you missed this Lightning Deal and to snag another great find? This essential oil diffuser is similar in size, lasts for 12 hours and diffuses your favorite essential oils with ease. Bonus? It's usually $33.99, but Amazon is currently offering a $5 off coupon. Score! Was this page helpful? Thanks for your feedback! Tell us why! Other Submit
