Things To Consider When Buying A Diffuser For Large Rooms

Tank Size

The most important element to consider first is the tank size. This refers to how much oil a diffuser can hold and in turn how long it will last before it needs to be refilled.

A small tank size of 50-200ml is suitable for your bedroom or bathroom. But for a large conservatory or dining room you’d want 200-400ml and if you need one for a spa, office or restaurant, you will want more than 500ml

Alternatively, to having one large powerful diffuser, you can have a number of smaller ones dotted around your area. This helps to spread out the vapours but requires more upkeep to make sure they are all working and well maintained. It also adds more clutter to your space.

A few models are sold in multipacks offering better value. We’ve taken a look at a couple of the best offerings for these in our article.

Running Costs

Running costs are an important factor to consider when buying a high-end diffuser. The larger more powerful ones use more electricity and get through a greater amount of essential oil in a shorter time. But they do have a greater ability to fragrance the environment effectively.

Smart Pairings

All of the diffusers featured in this list can be paired with a smartphone or tablet. This allows them to controlled remotely and set to a schedule. So they only diffuse when you need them.

Allowing you to create the most efficient rotations. If you are really into the smart home side of things, check out which are google home and Alexa compatible. So you can control your diffuser with your voice.

The guys over at mylittlesmarthome.com also offer great advice on building a suite of automated smart products for creating the right atmosphere. With a short command, the lighting, smell and sound in a space can be transformed to put you and your guests in an appropriate mood.

Appearance

When selecting your diffuser it’s useful to imagine, where you are going to put it and how will it look. It’s best to place a diffuser in the centre of the space it’s dispersing vapours into.

This is the best way to get the most out of your diffuser. Putting a diffuser in the centre of a space makes it more conspicuous. You may want an understated look that blends in with the existing decor or more of a statement piece.

We’ve explored options in both categories here. Whether you want a conversation starting gadget to take centre stage in your dinner party or you want a discreet diffuser that blends in with the environment and goes about its work silently – we’ve got you covered.

Another consideration on choosing a location for your diffuser is whether there is a power source close by and will there be unsightly wires running through the room.

Some of the diffusers offer rechargeable batteries, so they can be moved easily and avoid having ugly wires messing up the Feng Shui of your beautiful restaurant.

Reviews

We’ve selected the 10 best diffusers on the market for large rooms. We are going to take you through the main specifications and features, the ease of set-up, production quality, aesthetic and overall value for money. Looking at diffusers to suit all spaces and budgets.

1. Vitruvi Stone Diffuser


The Vitruvi Stone Diffuser is a beautiful object, it has a slightly phallic form but this only enhances the character of an extremely well-designed product. Each Vitruvi diffuser is handcrafted from the highest quality porcelain.

Compared to the many, wooden and plastic diffusers available this one really offers a great choice.

It may only have a 100 ml capacity, but being an ultrasonic diffuser it maintains the full integrity of the oils. It can cover a space up to 540 foot and has two settings, either 3 hours continuous or 7-hour intervals.

We love how easy it is to clean and the futuristic look. It could have more settings and connectivity options and the warranty is only valid in the US and Canada, but aesthetically this is a great choice.

2. Saje Diffuser by aromaOm


Made from ceramic and available in black and white this is an attractive offering for those looking for a product that is well designed and will fit into a considered space.

Perhaps a design studio or a holistic wellness centre. Coming in at 6.75 inches tall this is a compact non-obtrusive object. There is an optional LED light and the diffuser operates in near silence. It is suitable for a reasonably large space about a maximum of 1200 square feet.

Doubling up a humidifier, this is a classy offering from a well-established brand. A great choice for a large space. We highly recommend this diffuser for its ease of use, build quality, effectiveness in a large area and high-quality product design.

It may not have the best array of settings or a connected app but it does look fabulous. Best suited to the home or a small business. You could invest in multiple and place them around a larger space as we think they sit so wonderfully in any environment.

3. Raindrop 2.0


This is a fabulous nebulizer diffuser. That has many of the holistic benefits associated with a nebulizer diffuser. It won’t seep nasty chemicals and doesn’t use heat which can destroy the beneficial properties of the oils.

The raindrop diffuser is exceptionally elegant, with a curvaceous and alluring form, much like that of a shapely woman. It’s made from real wood which gives a quality finish to the diffuser. The glass reservoir is individually hand blown.

This is simply an excellent and unique product, that is well worth the extra few bucks. It comes in either a dark or light wood finish which allows the raindrop diffuser to fit in with any style.

Coming with a one year warranty this is a great buy for those who are serious about aromatherapy. Elegant, yet understated our top pick.

4. Zalik Diffuser


Coming in at the lower end but still packing a punch, this diffuser is suitable for a room in your home or a small cafe. With a wonderfully unique design , that looks a bit like a pumpkin, it lends itself to a quirky organic tea house or a yoga studio.

Packed full of character it’s a sure conversation starter. We quickly got this ultrasonic diffuser that doubles as a humidifier up and running.

It has three timer settings (two, four and six hours) and an auto switch off feature for when it runs out of oil. It also has a number of light settings which can be changed depending on your tastes.

A great thing about this diffuser is that it has a lifetime guarantee. So you can buy with confidence that it will last a lifetime of diffusing. Overall this is a decent offering as long as you don’t mind the pumpkin look.

5. Sierra Modern Home Diffuser


An ultrasonic diffuser with a large 400ml tank that offers exceptional connectivity and features at a very competitive price.

Not only is this diffuser compatible with Alexa and Google home, but it has its own companion app which allows you to control it from your smartphone and even create your own schedules. The led can also be controlled independently by the app.

We absolutely love the scheduling feature, we have ours set to have a different time operation at weekends to during the week. Making sure we get to bed on time and the diffuser isn’t on when we aren’t in. It’s a really great way of bringing a conventional product into a contemporary setting using technology.

You can operate it just like any other diffuser, with the added functions purely optional. Good looking with an unusual vase-shaped silhouette, this diffuser doesn’t feel quite as well built as some of the others we’ve tested.

But it’s got more than enough features to make up for this. A great option for those with a moderately sized space, on a budget and looking for the latest features.

6. Housemile 3rd Version


One of the better products on the market is the Housemile diffuser. It has a huge capacity tank at 600 ml, which for its class is one of the largest on the market. Making it perfect for a large space. It has long lasting potential and can go for up to 15 hours on a single tank.

Which is great for those with a large space to fill who don’t want to worry about refilling their diffuser all of the time.

One thing to bear in mind is that this essential oil diffuser doesn’t have a timer function built in. It also does not have an accompanying app for remote control. But it does have a high and low setting and is built for extended use.

A good choice for its design, tank size and ease of set-up. Could have more control over functionality.

7. Doukedge Dual Pack


This excellent value option includes two diffusers, each boasts 450ml tanks and is capable of diffusing a 400 square foot space. The diffusers are ultrasonic and double up as humidifiers.

An excellent choice for a large room in your house. The diffusers have led lights which can be set to eight different colors, this really allows you to set the right tone. The dark wooden finish would compliment a room with more subdued tones, either a bedroom or kitchen.

This option offers great value for a large space in a home or small business. The diffuser has four different timing settings running for 1 hour, 2 hours, 5 hours or always on.

The one-hour timer is great for putting on before you go to sleep. When the tank empties the diffuser automatically turns off, which is great for preserving energy.

One consideration is that there is no app so it cannot be programmed or controlled remotely. But offers great value otherwise and is a good-looking object and a fine entry-level model.

7. Aromacare 

Aromacare Essential Oil Diffuser, Aromatherapy Diffuser 1300 mL (0.35 Gallon), Ultrasonic Cool Mist Humidifier, Soothing Night Light, Great Mist Output for Large Bedroom, Baby Room, Home & Office

The Aromacare ultrasonic diffuser has a mammoth 1300ml tank. This is by far the largest we have found available on the market, making it ideal for large rooms.

The materials used are free from BPA and there is an automatic switch off function for when the system runs out of oil. The diffuser is operated via a dial which is found on the back. There isn’t an app but you can adjust the strength settings. The manufacturer offers a three-year warranty.

The Aromacare essential oil diffuser is a beast, it holds a gargantuan 1300ml (0.35 gallons) tank. This is very suitable for a large space and has a beautiful etched design on the outside, which glows in the dark.

Overall the Aromacare diffuser has a best in class capacity and looks elegant in the right surroundings. However, its controls are limited.

Type of Essential Oil Diffuser To Use In A Large Room

There are many different types of diffusers that diffuse oils in different ways. For larger areas, we recommend choosing one of these four types of diffusers.

Heat Diffusers

These are diffusers that use heat to raise the temperature of the essential oils until they evaporate into the air and disperse into space. They are really good for thick oils like sandalwood and cedar wood.

Heat diffusers have a little tray above the heat source which houses the oils. The heat source varies between diffusers (a few of these are; candle, electric or lamp)

One thing to bear in mind is that the heat changes the chemical composition of the oils and this often reduces their potency and beneficial effects.

But heat diffusers are a good budget option if you are looking for value and to get the job done.

Evaporative Diffusers

Like heat diffusers, evaporative diffusers also evaporate the oils into the air. However, an evaporative diffuser uses a fan to generate wind which helps the oil to be dispersed into the atmosphere in a controlled way. The oil is usually held in an absorbent material above the fan like a wick or a pad.

Nebulizer Diffuser

A nebulizer diffuser breaks down your essential oil into a fine spray and releases a highly concentrated mist. It does not use any water or steam and so the essential oil release is exceptionally potent.

This means it is often referred to as the purest way to disperse essential oils in aromatherapy. However, these diffusers have a habit of racing through your oil at light speed.

Ultrasonic Diffuser

These diffusers use a very specific ultrasonic vibration to break down the essential oils into tiny particles it then mixes these particles with stem and disperses them into the air.

An ultrasonic diffuser does not use heat and therefore maintains the quality of the oils. Diffusers that use heat as a heat diffuser destroys some of the oil through heating it. An ultrasonic diffuser is extremely quiet, which means it won’t draw attention and is ideal for working, relaxing or sleeping.

These diffusers use steam and so It can also be used as a humidifier.

 

Benefits of Having an Essential Oil Diffuser In A Large Space (Office, Restaurant or Dining Room)

If you want to help people feel comfortable, productive and keep them healthy. An essential oil diffuser for your large space could be a worthwhile investment.

Productivity

Want to raise your own productivity or boost the focus of your employees? Using an essential oil diffuser can help achieve this. Mixing the right blend of essential oils such as lavender and frankincense can help increase the concentration of those that inhale the vapors.

You could earn back the investment in an essential oil diffuser in increased output in weeks.

Safety

An essential oil diffuser is a safe and natural way to improve the health and wellbeing of those in the space.  Essential oils are safer than fragrant candles and incense which release harmful carcinogenic chemicals into the air through burning.

Relaxation

Aromatherapy is a great way to create the environment you want for the people in your building. An essential oil diffuser in your large space, be it an office or spa, can help your employees and customers relax.

Perhaps you’re looking for your team to be in peak form or trying to help stressed-out commuters enjoy their weekend. Use the right blend of essential oils such as peppermint and green tea and you can soothe the souls of those you care about.

Improved Immune System

Certain essential oil blends have the effect of boosting the immune system.

As you know this helps people fight off infection and illness. Leading to a reduced number of sick days from your employees and help in cutting the spread of harmful infections.

It’s an investment in the health of employees and your profit line. Make sure you choose the diffuser most suited to your space for the best results.

Fragrance

And of course, the scent, invigorating our senses in one hell of a way to feel alive. So tune in to the calming, beautiful scents of the natural world.

Atmosphere

One of the responsibilities as a host of any space or event is to create a suitable atmosphere. Clients, employees, friends and families, may not always remember what you said or what they did in your space.

But they always remember how they felt. An essential oil diffuser in a large space is a great unobtrusive way to set the tone and ambience that you want to keep. Aromatherapy gives you the flexibility to create blends that perfectly match the environment.

Be it a relaxing spa with lavender and chamomile. Or a  tech start-up that needs a boost of productivity and something to stimulate teamwork and creativity. Perhaps you are a counsellor and you want your clients to open up and relax in this setting.

If you’re anything like me, you need a hand getting up in the morning and an aid to unwind at the end of the day. An essential oil diffuser is a great string to the bow of any host. An indispensable tool in creating the experiences you deserve.
