How to choose an essential oil diffuser
You could choose from literally hundreds of oil diffusers that range in price from $10 to more than $100. Before you buy, consider these factors in selecting the best essential oil diffuser.?
Capacity: Diffuser water capacity can run anywhere from 100 milliliters (3.4 fl. oz.) of water to more than 1 liter (32 fl. oz.) of water, but the average sits around 300 milliliters. You may want a larger water capacity if you don't want to be bothered to refill the water very often, or if you need your diffuser to run for a long time in a large space.
Run time and timers: Do you want to be able to set your diffuser for one, three or five hours? Do you want a continuous run option for aroma and mist? How long do you need it to run for? These are all important questions to consider when purchasing a diffuser.?
Automatic shutoff: Even if you're typically not a forgetful person, choosing a diffuser with auto shutoff is a smart move. If you forget to power down your diffuser when there's little water left, it can overheat and break.?
Area coverage: For small rooms, you don't need to worry too much about the square footage your diffuser covers. If you're looking to use it in an open space or large room, however, look for diffusers with a high square footage.?
Lighting: Many diffusers offer ambient LED lights and/or double as night lights. This is very much a personal preference thing, so if you definitely don't want a light, make sure the diffuser you want to buy doesn't have one, or that you can easily turn it off.
Mist settings: Do you want a continuous cool mist that runs for hours for diffusing essential oils, or an intermittent mist??
Intensity: For a stronger scent or mist, look for nebulizing diffusers. Nebulizer diffusers vaporize the oil before pumping out the fine mist. These are often more expensive than standard diffusers, but can be worth it if you find standard diffusers to be weak.?
Humidity: Many essential oil diffusers double as a cool mist humidifier. This can be a great two-in-one option if you live in a dry climate.?
