As its name suggests, this type of diffuser works by heating the essential oils which will then release their aromas.
There are two main ways to propagate aromas through heat.
The first is the perfume burner with a candle. However, this is not a “gentle” heat diffusion because the temperature obtained by this process is much too high, which tends to destroy the properties of essential oils, which lose their benefits above 40°C.
That is why electric soft heat diffusers have been developed. Some models plug directly into a wall outlet, while others have a power cord. Mostly made of porcelain, they are equipped with a resistor that regulates the temperature so that the diffusion is optimal. The most basic models are in fact cups into which the oils are poured, while other more sophisticated models play on shapes and options.
This way, you can find diffusers that operate on a cycle basis or for which you can adjust the broadcasting time. Some even have LEDs, which can be used as night lights or to create a soothing atmosphere.
Soft heat diffusers are among the simplest to use: a few drops of oil in the dedicated cup, press the switch and diffusion can begin. They are also quick and easy to maintain, as they can be wiped clean with a damp cloth and a little alcohol.
You may choose these models of diffusers if
You are looking to make a small, light and non-intrusive diffusion to create an atmosphere
You don’t want any noise
You would like a small and inexpensive essential oil diffuser to start with.
Advantages of a Soft Heat Diffuser:
The gentle heat does not degrade the properties of the essential oils (thermoregulated resistance),
No maintenance (a little wipe and alcohol is enough),
Aesthetic models, which make them real decorative objects,
Suitable for small rooms such as a bedroom or office.
Disadvantages of a Soft Heat Diffuser:
Not very powerful, this type of diffuser will only be able to cover small areas (maximum 20 m²).
The diffusion is slower. Be patient, it may take 10 to 15 minutes before the particles smell.
Some essential oils that are “a little heavy” such as citrus fruits have difficulty being diffused, on the other hand, light essential oils such as eucalyptus are very well diffused.
