Myth What about the viral claim? Are essential oil diffusers better than air fresheners? 

Why make the swap

Questions people ask

Are plug-in air fresheners safe?

Plug-in air fresheners aren’t a clean choice: they give off terpenes around the clock, which react with ozone indoors to form formaldehyde and ultrafine particles, and they don’t remove smells.

Is an essential-oil diffuser a cleaner alternative?

Not really: diffusers release the same terpenes, and some oils are dangerous for cats.

What gets rid of smells instead?

Open a window or run the fan. In a closed room, a charcoal bag soaks up lingering smells, and a HEPA purifier is the bigger step.

Are essential-oil diffusers safe around cats?

Not always. Many essential oils can be toxic to cats, and diffuser droplets settle on fur that cats lick off. Keep diffusers out of the rooms your cat uses. More: Are essential oils safe for cats and dogs?
