Professional fragrance diffuser: which one to choose depending on the area to be scented?

In a professional setting, the diffusion of a room fragrance is never left to chance. It influences how your customers perceive your brand, the fluidity of their journey and the quality of the experience you offer them. But to enhance a fragrance created in Grasse and preserve all the subtlety of its composition, you need to use a diffuser that is ‘truly’ suited to the layout of your premises.

In the field, we encounter 50 m² shops with automatic doors that are always open, spas organised into partitioned cubicles, 600 m² hotel lobbies with high ceilings, and long sales areas where air circulates irregularly. In each of these environments, the same fragrance does not express itself in the same way.
This is why the selection of a diffuser should never be limited to a simple indication of surface area: it must take into account many factors such as the type of entrance, the cash desk or reception counter, the structure of the premises, the flow of traffic and the desired level of intensity.

With a professional range covering areas from 20 m² to over 4,000 m², Premium Fragrances allows you to orchestrate precise, stable and perfectly controlled diffusion. This guide has been designed to help you identify the most appropriate diffuser for your space and configuration, ensuring a consistent, elegant result that stays true to the olfactory DNA you wish to convey.

Understanding fragrance diffusion in a professional environment

The diffusion of a fragrance in a professional environment depends not only on the choice of scent, but also on how it circulates and settles in the space. For the notes created in Grasse to reveal their full elegance, it is essential to understand how a place ‘breathes’: its air volume, its points of opening, its geometry and the habits of passage.

Here are the key parameters that influence broadcasting and should guide your choice of broadcaster.

Surface area or volume: two different realities

In an olfactory project, surface area in square metres is only a partial indicator. What really determines a diffuser’s performance is the volume of air to be scented.

• A 60 m² shop with a 2.40 m ceiling does not have the same requirements as a 60 m² space with a 4-metre ceiling.
  
• Similarly, a compact space will provide more enveloping diffusion than an open area with a larger total air volume.

The greater the volume, the more the diffuser must be capable of delivering stable, consistent diffusion that is powerful enough to reach all areas of the space.

Air flow: air conditioning, circulation and open doors

Air movements directly influence the way the fragrance unfolds.

• Automatic or continuously open doors: these create a natural ‘leak’ of fragrance to the outside and require a diffuser that is sized accordingly or positioned away from the entrance.
  
• Internal air conditioning and ventilation: these can direct diffusion, create lighter or more intense areas, and must be taken into account to avoid imbalances.
  
• Natural circulation: the passage of customers and the opening of booths or adjacent spaces alter the dynamics of the fragrance throughout the day.

Understanding these movements allows you to anticipate variations and adjust the power or location of the diffuser.

Layout of the venue: open, partitioned or long and narrow

The very structure of your space determines how the scent spreads.

Open spaces

Reception areas, open spaces, circulation areas: diffusion is more uniform, but the total volume of air is greater. Diffusers capable of covering large areas should therefore be used.

Partitioned spaces

Treatment rooms, partitioned lounges, dedicated rooms: each room has its own air dynamics. Depending on the surface area, it may be appropriate to use a single diffuser placed in a central area or several diffusion points.

Long spaces

Narrow shops, galleries, concept stores: air often flows in ‘corridors’, which can create areas that are more fragrant than others. A sufficiently powerful or judiciously placed diffuser can provide a consistent experience throughout the entire depth of the space.

Desired intensity: a question of brand identity

The question is not only ‘what surface area?’, but also what olfactory intention.
Some brands want a light and subtle presence; others are looking for a more assertive signature that accompanies the customer from the moment they enter. The choice of diffuser must therefore offer a margin of adjustment to achieve exactly the desired intensity, without excess or areas that are too weak.

Premium Fragrances diffuser families and their target surfaces

Each professional space has its own constraints: a 120 m² reception area has nothing in common with a 40 m² waiting room, a partitioned spa or a hotel lobby measuring several hundred square metres. To ensure that your room fragrance created in Grasse expresses all its finesse, it is essential to use a diffuser that is truly suited to the air volume and layout of your establishment.

The Premium Fragrances range covers needs ranging from small, intimate spaces to very large environments.

Here is how to guide your choice.

TINY 1 and TINY 2: for small spaces up to 100 m²

Designed for environments where precision and discretion are essential, TINY 1 and TINY 2 offer perfectly controlled diffusion over areas of up to 100 m².

When should you choose a TINY model?

• Small shops
  
• Waiting rooms
  
• Welcoming reception areas
  
• Fitness studio
  
• Premium offices or cosy spaces

In these configurations, a TINY allows the fragrance to be released accurately, without excess, while maintaining a constant olfactory presence. Their Bluetooth control makes adjustments easy and allows for fine tuning to suit the pace of your activity.

Recommended usage range

Although designed to cover 100 m², they offer their best balance in spaces between 20 and 80 m², depending on the layout of the premises and air circulation.

MEDIUM 1 and MEDIUM 2: for medium-sized spaces up to 800 m²

When the surface area to be scented increases, the diffuser must be capable of covering a much larger volume of air. The MEDIUM 1 and MEDIUM 2 diffusers meet this challenge precisely thanks to their capacity to diffuse up to 800 m².

MEDIUM 1: visual elegance and balanced diffusion

With its acrylic front, this model fits naturally into places where aesthetics are as important as performance. It is ideal for spaces that are open to the public throughout the day.

MEDIUM 2: powerful ventilation and high efficiency

Equipped with a reinforced dispersion system, it is ideal for spaces with regular air flow (air conditioning, internal ventilation) or places requiring greater intensity.

When should you choose a MEDIUM model?

• Clothing shops
  
• Showroom
  
• Events, conference rooms
  
• Spacious waiting rooms

• Intermediate traffic zones

Recommended usage range

• 80 to 300 m² for a refined and uniform result.
  
• Up to 800 m² depending on the configuration (open spaces, high ceilings, moderate air flow).

PLAZA 2: for large spaces up to 4,000 m²

For large environments with high traffic flow, the PLAZA 2 diffuser is designed to diffuse fragrance over areas of up to 4,000 m².

High capacity and independent tank for very large spaces.

Its 5-litre tank allows it to operate for several weeks, even in the most demanding environments. It is the preferred solution for locations where diffusion must remain continuous, despite high air circulation.

When should you choose a PLAZA model?

• Hotel lobbies
  
• Shopping centres
  
• Event spaces
  
• Art galleries
  
• Open floor plans and areas with very high ceilings

Recommended usage range

From 500 to 4,000 m², adapting the diffuser positioning to the natural air flow and ceiling height.

Case studies: choosing the right diffuser for your establishment

The examples below illustrate real-life configurations encountered in retail, hospitality, wellness and circulation areas. They show how to adapt the choice of diffuser to the structure of the space, its air volume, air flow and the desired olfactory effect.

Shop measuring 50 to 70 m² with automatic door opening onto the street

Background

This configuration is one of the most common in retail. The shop is often long and narrow, with an automatic door that opens and closes continuously. Each time the door opens, some of the air inside is sucked out, creating a “cold zone” near the entrance.

The fragrance therefore tends to dissipate, and the olfactory concentration varies throughout the day.

Challenges

• Maintain a consistent atmosphere despite variations in air quality.
  
• Avoid excessive diffusion at the entrance but insufficient diffusion at the back of the shop.
  
• Make the fragrance noticeable from the very first few metres, without saturating the space.

Recommended diffuser

TINY 1.

Why this choice?

The Tiny 1 offers power that is perfectly suited to areas of up to 100 m², while allowing for precise control. It is ideal for shops where the atmosphere needs to remain subtle, elegant and consistent.

Optimal positioning

• Never directly near the door: the signal would be too disrupted.
  
• Preferably mid-length, if possible close enough to the entrance to guarantee a ‘wow’ effect. Slightly raised (shelf, wall unit).
  
• Away from direct air conditioning or ventilation flows.

Expected result

A stable, consistent atmosphere that accompanies the customer throughout their visit without losing intensity at the entrance.

120 m² beauty salon or spa divided into partitioned treatment rooms

Background

A spa or beauty salon often has several distinct areas:

• a welcome,
  
• one or two waiting rooms,
  
• several enclosed cabins,
  
• a corridor leading to the treatment rooms.

Challenges

• maintain discreet broadcasting in communal areas.
  
• offer a more distinctive signature in the reception area.

Recommended diffuser

TINY 1 for the traffic area.

MEDIUM 1 for reception.

Why this choice?

Small spaces require a subtle, almost imperceptible scent: a TINY diffuser creates a soothing, perfectly controlled atmosphere.

The reception area, meanwhile, should have a warm, more open feel: the MEDIUM 1 diffuser ensures stable, elegant diffusion without excess, especially if the space is large.

Optimal positioning

• The TINY diffuser should be placed in a discreet corner, at chest height or lower. This is because odours tend to rise.
  
• The MEDIUM 1 diffuser positioned at the reception area, creating a central diffusion point that extends naturally towards the corridor.

Expected result

An olfactory consistency that accompanies the customer from the moment they arrive, then delicately modulates as they make their way to the cabin.

Hairdressing salon measuring 100 to 150 m² with active ventilation

Background

Hairdressing salons are dynamic environments:

• doors often open,
  
• active ventilation,
  
• constant air circulation,
  
• areas of heavy traffic around containers and technical stations.

The air is renewed quickly and intermittently, which requires sufficiently powerful diffusion to remain noticeable.

Challenges

• offer an olfactory footprint that resists internal flows.
  
• avoid sudden changes in temperature between the entrance, the waiting areas and the hairdressing stations.
  
• adjust the intensity according to peak hours.

Recommended diffuser

MEDIUM 1.

Why this choice?

The MEDIUM 1 diffuser is perfectly suited to spaces where air circulates more freely. It helps maintain a stable atmosphere, even when the lounge is very lively.

Optimal positioning

• On a side wall, at low or medium height, away from direct ventilation sources.
  
• Never right next to a technical station.
  
• Ideally in the centre of the volume for balanced diffusion.

Expected result

An elegant and consistent atmosphere, evident at the entrance as well as at the bins and counter.

Hotel lobby measuring 300 to 600 m² with high ceilings

Background

A hotel lobby is one of the most demanding environments:

• high ceilings,
  
• considerable volumes of air,
  
• continuous flow of visitors,
  
• open spaces leading to lifts, reception, sometimes a lounge.

In these places, a diffuser that is too light loses its effectiveness, and the scent quickly fades away.

Challenges

• cover a substantial volume evenly.
  
• ensure a noticeable yet elegant scent.
  
• ensure a stable atmosphere throughout the day.

Recommended diffuser

PLAZA 2.

Why this choice?

The PLAZA 2 diffuser is designed for large volumes. It offers intensity and amplitude capable of permeating the entire hall without creating ‘empty’ or overloaded areas.

Optimal positioning

• At a low or medium height, to encourage propagation.
  
• By avoiding blind spots or large obstacles.
  
• Possibility of working in several areas via strategic placement if the hall is highly segmented. This diffuser can also be installed in the air conditioning system – only by specialised service providers.

Expected result

An immediately noticeable olfactory welcome, consistent from morning to night, perfectly integrated with the hotel’s image.

Concept store measuring 150 to 300 m² in open space

Background

Concept stores often have modular layouts:

• central furniture,
  
• discovery areas,
  
• smooth traffic flow,
  
• semi-open ceiling or variable height.

The aim is to envelop visitors in a consistent atmosphere, while respecting the desired sensory identity.

Challenges

• harmonise broadcasting in an evolving environment.
  
• maintain a consistent scent even when rearranging the space.
  
• support the customer journey seamlessly.

Recommended diffuser

MEDIUM 2.

Why this choice?

MEDIUM diffuser models provide ample yet precise diffusion, perfectly suited to modern, airy spaces where the fragrance needs to be dispersed over a medium to large area.

Optimal positioning

• In the central area, slightly elevated.
  
• Close to entry points or high-traffic areas to create a wow effect as soon as visitors enter.
  
• Possibility of adjusting the schedule to accommodate peak hours.

Expected result

An olfactory identity that is perfectly integrated into the concept of the place, perceived consistently, without excess.

What is the takeaway?

Finding the right professional diffuser is never just a matter of choosing a device for a given surface area. It is a strategic process that involves understanding your space, its flow, its air currents and the experience you want to offer. A fragrance created in Grasse expresses its full subtlety only when diffused with precision, stability and elegance.

By selecting a diffuser suited to your air volume, configuration and desired intensity, you are doing much more than just perfuming a space: you are creating a true sensory marker, capable of anchoring your brand identity in the memory of your visitors.

With a range covering environments from 20 to over 4,000 m², Premium Fragrances allows you to create a tailor-made, consistent and perfectly controlled olfactory atmosphere. For a warmer welcome, a smoother customer journey or an instantly recognisable signature scent, each diffuser becomes a strategic tool that enhances your image and conveys the excellence you wish to project.
