What Essential Oils Make Your House Smell Good In A Diffuser?

Essential oils have been used for thousands of years for their health, beauty, and aromatic benefits.

Usage Tips

Proper usage is key to getting the most out of your essential oil diffuser. Here are some tips to follow:

Ideal diffuser placement is important. Diffusers work best in smaller rooms, so place it in a bedroom, office or living room. Don’t put it in a large open area or too far away to experience the aroma benefits. Also avoid areas with high humidity or moisture as this can impact diffusion (YoungLiving).

Ambient factors like air flow, temperature and humidity impact diffusion. Oils diffuse best at normal room temperature. Avoid drafty areas or direct air flow from fans, vents or open windows as this will disrupt diffusion. Low humidity helps diffusion so avoid steamy rooms like bathrooms (RecipesWithEssentialOils).

Be sure to clean diffusers regularly according to manufacturer instructions. Use a damp cloth to wipe any oil residue from the ultrasonic plate or inner surface. Empty any remaining water and allow to fully dry before next use (RecipesWithEssentialOils).


When diffusing essential oils, it’s important to be aware of potential safety issues. Some key things to keep in mind:

Ventilation – Make sure the room you are diffusing oils in is well-ventilated. Open windows or run fans to allow fresh air flow. Avoid diffusing for prolonged periods in enclosed, unventilated areas (Healthline).

Sensitivities – Test oils on a small area of skin first to check for any sensitivities or allergic reactions before diffusing. Dilute oils with a carrier oil if applying topically. Some oils like lavender may cause complications for children and teens (CNET).

Pets – Research which essential oils may be unsafe for pets, especially cats and dogs. Consider diffusing in a separate room away from pets. Discontinue use if pets exhibit unusual symptoms or discomfort (Health.com).

Moderation – Use oils in moderation. Overexposure through excessive inhalation may lead to headaches, nausea or other symptoms. Follow manufacturer guidelines and adjust as needed.

Proper Storage – Store oils properly when not in use to maintain their integrity and reduce accidental ingestion. Keep out of reach of children.

With some basic precautions, essential oils can be safely diffused to make your home smell pleasant. But be sure to educate yourself on proper usage and potential risks.
