Our take on the Coffee and Black Forest Design Iron Essential Oil Diffuser - 7 Color LED Ultrasonic Cool Mist Humidifier 100ml

The During Days Forest Iron Art Aroma Diffuser is a 100ml ultrasonic diffuser with a coffee-and-black-forest iron finish and seven LED colors. It runs under 35 dB(A) and covers roughly 20-40 square meters, so it suits a bedroom or small living room. The best new price is $17.99 at Amazon as of November 8, 2026, and only one store lists it new, so there is no cheaper alternative to compare against.

Questions and answers

How long does the 100ml tank last?
At a typical mist rate a 100ml tank runs a few hours per fill, so expect to refill most nights. Run it on the intermittent setting to stretch a fill further.
Does it come with essential oil?
No. Essential oils are not included, so budget for a bottle separately. Add a few drops of water-soluble oil to the tank.
Is it quiet enough for a bedroom?
Yes. It is rated under 35 dB(A), which is about the level of a soft whisper. Most people will not notice it at night.
What room size does it cover?
The rated coverage is 20-40 square meters. That fits a bedroom or small living room; larger open spaces will need more than one unit.
Is $17.99 a good price?
Only one store lists it new at $17.99 as of November 8, 2026, so there is no lower price to compare against. At that price it is a low-cost entry diffuser.
Does it need distilled water?
Distilled or filtered water is recommended. Tap water minerals can clog the ultrasonic plate and leave white dust on nearby surfaces.
Where is the Coffee and Black Forest Design Iron Essential Oil Diffuser - 7 Color LED Ultrasonic Cool Mist Humidifier 100ml cheapest?
At Amazon, for $17.99, as of our latest check.
