Conventional Aroma Diffuser Systems

❌ Avoid Conventional diffusers or conventional essential oils: they can contain dozens of undisclosed and often untested chemicals. I collected the most organic essential oils and aroma diffusers on the market; they are all listed on this page. They will refresh your home without exposing you to unknown and highly toxic chemicals hidden inside conventional fragranced air spray products.

​

❌ Because both the odor-eliminating formulations and the fragrances are considered to be trade secrets by the U.S. Food and Drug Administration (FDA), brands are exempt from having to list the ingredients included in their air freshener.  

Greenwashing Aroma Diffusers

❌ Avoid greenwashing aroma diffuser brands that pretend to be safer or more sustainable when they are not. Even if they offer organic essential oils, they use water as a delivery system, which can cause mold. Often also spew small allergens into the air, which are not healthy to breathe in and may cause irritation to the skin and nasal passages. 

 

Pet owners: According to 24petwatch: “It’s best to avoid diffusing essential oils around dogs and cats. In addition to inhalation exposure to potentially toxic essential oils, microdroplets of oils could collect on your pet’s fur. This exposure could lead to dermal absorption or eventual ingestion once your pet grooms or licks itself. If you decide to diffuse essential oils in your home, it is recommended that you do so for a brief period, in an area separate from your pets. Additionally, make sure that your dog or cat cannot access the essential oil diffuser – and potentially expose themselves to essential oils in the process.”

Approved Aroma Diffusers

🌿 For all these reasons, I dug into the market and collected only the approved brands that make organic and essential oils and aroma diffusers.

✅ Waterless Aroma Diffusers: Aroma diffusers that use water as a delivery system often also spew small allergens into the air, which are not healthy to breathe in and may cause irritation to the skin and nasal passages.  That is why I listed only waterless devices here! The best aroma diffusers on the market.
