How to Choose the Best Diffuser for Your Large Room
Picking the best diffuser for a large room is more complex than buying the one that looks the coolest. The aesthetic is only part of the shopping experience. You should also consider these criteria.
Most diffusers are electrical, with the two most popular essential oil diffusers for large rooms being ultrasonic and nebulizers.
Ultrasonic diffusers create an oil mist through electronic ultrasonic waves. This method is quiet and will disperse strong oils through an area. In addition, many of these models have built-in lighting and can work as humidifiers for cleaner air.
Nebulizers are a more popular electric essential oil diffuser for large spaces. These large room diffusers use a high-pressure pump to force oil through a narrow nozzle. As a result, you get longer-lasting aromas, less oil usage, and preserve the oil’s therapeutic properties.
Another great essential oil diffuser for large room is a reed diffuser. A reed diffuser for large room is more affordable and versatile. There are three parts to a reed diffuser – a glass container, reed sticks, and essential oils. Add oil into a bowl or jar then arrange seven wooden reeds inside. The oil soaks into the reed sticks and releases into the air in all directions.
Diffusers have different water tank sizes, affecting the machine’s operation time. Tank sizes range from 100 milliliters (a small compact size) to extra large room diffusers with 550 mL.
To determine what size oil diffuser for large room, you’ll need to know the estimated area you’ll need to cover. Determine your measurement in square footage and then check if the large room oil diffusers can accommodate the size. A small oil diffuser with a low-capacity tank will cover less space with shorter run times, but it can be appropriate for infrequent operation.
Diffusers can vary in price, with many smaller models costing less than $50. But you can also get larger, more advanced diffusers that are a few hundred dollars. Most inexpensive oil diffusers for large rooms will do an appropriate job as long as it has the space capacity.
Run time is crucial for picking the appropriate oil diffuser for your large space. Most diffusers have a customized run time from one hour up to eight hours, with the longest run times being 10 to 12 hours of continuous operation.
Many oil diffusers come with built-in timers that allow you to set how long the diffuser will put out a mist of fragrant oil. The timing can range, with several models allowing for multiple times, such as 1 hour, 3 hours, 6 hours, or 12 hours.
Safety features like automatic shut-off prevent oil diffusers from overheating or burning up due to running once the water tank runs empty.
Some electronic large room humidifier and diffuser models allow for the operation of the controls and settings via remote control. These models make it easier to tweak the level of mist, run time, and light cycles without having to interact physically with the machine.
Diffuser Smart Features
Smart features allow for easier operation and more customization. For example, some models of diffusers connect to WiFi so you can control the settings with your voice, a smart device like Google Home, Alexa, or other home assistants, and apps.
Diffusers can have different mist levels, typically slow and high rates. The mist refers to how the oil disperses from the diffuser. The strength of the mist dispersion affects the intensity of the aroma and where you place your diffuser in the room.
Diffusers can produce multiple noises, whether from the sound of the oil coming out or the operation of the device. An optimal noise level for the best diffuser for open floor plan, nurseries, or bedrooms is less than 25 dB – 20 dB is the sound of a whisper from five feet while 30 dB is a soft whisper.
Picking a diffuser with lights can create a soothing ambiance of dim lighting for relaxing sleep or as a child’s night light. Or it can make a fun display of multi-color lights for large living rooms and game rooms.
Diffusers come in various shapes, sizes, colors, and materials, giving you many looks to consider. Basic models have a simple form and no aesthetical extras while other oil diffusers look like artwork in unique shapes and colors.
