Hotel lobbies, at home.
Without the front desk.

The Pro 2 was built around one question: how do the finest hotels in Marrakech, Paris, and Kyoto scent their vast lobbies without anyone ever noticing the machine? The answer is cold-air diffusion — a silent mist of fragrance that fills a 2,000-square-foot room evenly, without heat, water, smoke, or a single visible trace of where it came from.

You will forget it is there. Which is the point.

What is the Diffuser Pro 2?
The Diffuser Pro 2 is the flagship Scentiment cold-air diffuser — built to scent open-plan homes, offices, hotels, and commercial spaces up to 2,000 sq ft. It uses a precision air pump to disperse pure, undiluted fragrance oil as a dry micro-mist with no water, no heat, no batteries, and no aerosol propellants, so the full molecular profile of every oil reaches the room intact. Pairs with our refillable 200 ml fragrance oil bottles and the Scentiment app for Wi-Fi / Bluetooth control, schedules, intensity tuning, and refill alerts.
How is the Diffuser Pro 2 different from our other diffusers?
Same cold-air diffusion technology, larger footprint, larger bottle, larger coverage. The Diffuser Pro 2 is rated up to 2,000 sq ft with a 200 ml refillable bottle — the right tier for a whole-house, an open-plan loft, a restaurant or hotel lobby, or any space where smaller diffusers would run undersized. For comparison, see the Diffuser Air 2 (up to 1,000 sq ft, single-room aluminum cylinder for bedrooms, studios, and offices), or the Diffuser HVAC 2 (up to 5,000 sq ft, commercial-grade with HVAC integration for whole-building scenting). All pair with the same Scentiment app and the same fragrance oil library — choose by room, layer freely.
How long does a 200 ml bottle last in the Diffuser Pro 2?
A 200 ml bottle lasts approximately 8–14 weeks on default Medium intensity at 12 hours per day — run-time scales with three things: intensity setting, daily run hours, and room size. Low intensity stretches each bottle substantially further; High intensity (used before guests arrive or in rooms with active airflow) shortens it. Auto-replenishment in the Scentiment app ships refills before you run out.
How much area does the Diffuser Pro 2 cover?
The Diffuser Pro 2 is rated for up to 2,000 sq ft with normal residential ceiling heights (8–10 ft). If your space is a different size, see Diffuser Air 2 (up to 1,000 sq ft) or Diffuser HVAC 2 (up to 5,000 sq ft). Coverage assumes a normally insulated room with average air circulation; open-plan layouts, vaulted ceilings, or rooms with constant airflow may need a step up in tier.
How loud is the Diffuser Pro 2?
The Diffuser Pro 2 runs on intermittent ON/OFF cycles — a short pump burst followed by 2–5 minutes of silence depending on intensity. The pump itself is quiet and inaudible from a few feet away. For context, a refrigerator hum is 40–45 dB, an air purifier on low is 35–50 dB, and a quiet bedroom at night measures around 30 dB. Most owners describe the cycle as a soft whisper you stop noticing after a minute in the room.
Is the Diffuser Pro 2 safe for pets, children, and people with allergies?
Yes. Every Scentiment fragrance is IFRA-certified to Category 11 (the strictest air-care tier) and formulated without phthalates, parabens, formaldehyde, California Prop 65 reproductive toxins, and the essential oils most commonly cited as toxic to cats and dogs (tea tree, pennyroyal, pine, wintergreen, sweet birch, concentrated citrus). Cold-air diffusion produces no heat, no combustion byproducts, and no surface residue — important for nurseries, beds, and pet spaces. We disclose all 26 EU Annex III fragrance allergens on each scent's product page so families with sensitivities can choose accordingly.
How do I clean and maintain the Diffuser Pro 2?
Maintenance is minimal. Whenever you change scents, run a brief cleaning cycle with 70% isopropyl alcohol — pour a small amount into the empty bottle, run the Diffuser Pro 2 for 5–10 minutes on High, then dry. This clears residual oil from the air channel so the next scent comes through clean. Wipe the exterior with a soft microfibre cloth (no harsh solvents, no water inside the air pump). The bottle can be rinsed with warm water and a drop of mild dish soap between scents.
Does the Diffuser Pro 2 have an app or Bluetooth control?
Yes. The Diffuser Pro 2 pairs with the Scentiment app (iOS and Android) over Wi-Fi and Bluetooth Low Energy. From the app you can switch between intensity settings, set daily ON/OFF schedules, run pre-arrival scenting routines, monitor estimated bottle life, and order refills. The unit also has on-device controls so it works without the app — useful for guest rooms or rentals.
Where should I place the Diffuser Pro 2 for best results?
Place the Diffuser Pro 2 on a stable, elevated surface — a console table, credenza, or built-in shelf — as close to the center of your open-plan space as practical. Cold-air micro-mist follows natural room convection, so a spot near a hallway junction, stairwell opening, or air-return vent helps fragrance travel without raising intensity. Leave at least 3 feet of clearance on all sides so the mist disperses freely; avoid tucking the unit into a tight bookshelf niche or behind large furniture that blocks airflow. For whole-house scenting, positioning near the central air-return pulls fragrance through the HVAC system passively — not as forcefully as the Diffuser HVAC 2, but enough to carry scent into adjacent rooms.
How does cold-air diffusion work, and why is it better than heated plug-ins?

Cold-air nebulizing diffusion pushes pressurized air across the surface of fragrance oil to break it into micro-droplets between one and three microns in size. Those droplets evaporate within seconds, distributing scent evenly through a room without heating or diluting the oil.

  • Versus heated plug-ins (Glade, Air Wick, Bath & Body Works): Those gently heat a wax or oil reservoir, which alters and partially destroys the top notes you actually paid for. Cold-air diffusion delivers the full molecular profile of the fragrance unchanged.
  • Versus reed diffusers: Reed diffusers rely on capillary evaporation, which is slow, uneven, and weakest in larger or air-circulated rooms. The Diffuser Pro 2 delivers consistent intensity at the tap of a button.
  • Versus wax warmers and candles: Both involve combustion or heat and produce byproducts (soot, formaldehyde, benzene with paraffin). The Diffuser Pro 2 emits only the fragrance itself.
How does Scentiment compare to Pura, Aera, Glade, or Bath & Body Works plug-ins?

The most useful comparison is technology, refill economics, and fragrance quality:

  • Versus Pura: Pura uses sealed proprietary capsules with a heated micro-pump in a smart plug-in housing. Scentiment uses a refillable bottle with cold-air nebulizing — no heat, no plastic capsule waste, and an open fragrance library. Both have an app; ours doesn’t lock you into capsule reorders.
  • Versus Aera Mini: Aera Mini also uses sealed proprietary capsules with a small fan. Scentiment uses cold-air pump diffusion with a refillable bottle — better long-run refill economics and a fragrance library that includes hotel-tier oils, not just retail collaborations.
  • Versus Glade PlugIns, Air Wick, Bath & Body Works Wallflowers: Those gently heat a wax or oil reservoir to evaporate fragrance — the heat alters the scent and the units run continuously, masking rather than scenting. The Diffuser Pro 2 uses unheated cold-air diffusion at a fraction of the daily oil consumption.
  • Versus reed and ultrasonic diffusers: Reeds rely on slow, uneven evaporation; ultrasonic units mix scent with water and leave residue. The Diffuser Pro 2 delivers a dry, consistent scent on a programmable schedule.
What’s the warranty and return policy?

The Diffuser Pro 2 comes with a one-year limited warranty covering manufacturing defects and pump performance, plus our 30-day risk-free return. If you don’t love it within 30 days of delivery, we’ll arrange a free return shipment and refund — no restocking fee. Optional Protect+ coverage at checkout extends accidental-damage protection beyond the standard warranty. Refill bottles are non-returnable once opened for hygiene reasons but can be exchanged unopened. Read the full Refund Policy for details.

Can the Diffuser Pro 2 run continuously, 24/7?

The unit runs on intermittent ON/OFF cycles by design — even on High it pumps for 30 seconds, then rests for two minutes — so true 24/7 operation isn’t a concern the way it is with always-on heated plug-ins. We don’t recommend leaving any diffuser running continuously for residential use, though: continuous diffusion saturates a room past the point where the human nose registers the fragrance (a phenomenon called olfactory adaptation), so you stop noticing the scent while still consuming oil. The default Medium schedule with the unit turned off overnight strikes the right balance for most rooms.
