The signature scent
of your favorite room.

The Air 2 is sized for a single room — the bedroom you wake up in, the studio you work from, the entryway guests step into. Same hotel-grade cold-air diffusion as our flagship, just in a slimmer aluminum cylinder that vanishes into a bookshelf or sits beside a candle on a console. Up to 1,000 square feet of consistent, programmable scent without heat, water, smoke, or a single visible trace.

One room. One scent. One small object you'll forget is there.

Questions we hear often

What people ask, answered.

The questions our concierge team and the internet send our way most about single-room cold-air diffusion. If yours isn’t here, write to support@scentiment.com — a real person replies within one business day.

What is the Diffuser Air 2?
The Diffuser Air 2 is a Scentiment cold-air diffuser sized for the single-room tier — primary bedrooms, studios, home offices, large entryways, and any space up to 1,000 sq ft where you want a consistent, ambient scent without a console-top device. It uses a precision air pump to disperse pure, undiluted fragrance oil as a dry micro-mist — no water, no heat, no batteries, no aerosol propellants. Pairs with our refillable 120 ml fragrance oil bottles and the Scentiment app for Wi-Fi / Bluetooth control, schedules, and refill alerts.
How is the Diffuser Air 2 different from our other diffusers?
Same cold-air diffusion technology, single-room footprint. The Diffuser Air 2 is up to 1,000 sq ft with a 120 ml refillable bottle — the right tier for a primary bedroom, a studio, or a home office. For comparison, see the Diffuser Mini 2 LE (up to 500 sq ft, portable, USB-C-rechargeable, sized for small rooms or travel), or the Diffuser Pro 2 (up to 2,000 sq ft, open-plan flagship for whole-house and commercial spaces). All pair with the same Scentiment app and fragrance oil library — choose by room, layer freely.
How long does a 120 ml bottle last in the Diffuser Air 2?
A 120 ml bottle lasts approximately 6–10 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 Air 2 cover?
The Diffuser Air 2 is rated for up to 1,000 sq ft with normal residential ceiling heights (8–10 ft). If your space is a different size, see Diffuser Mini 2 LE (up to 500 sq ft) or Diffuser Pro 2 (up to 2,000 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 Air 2?
The Diffuser Air 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 Air 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 Air 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 Air 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 Air 2 have an app or Bluetooth control?
Yes. The Diffuser Air 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 Air 2 for best results?
Set the Diffuser Air 2 on a nightstand, shelf, or desk in the room you want to scent — about waist height or higher works best because the micro-mist rises and spreads with natural air currents. Avoid placing it directly on the floor, in a tight corner, or right next to an AC vent that would push the mist away before it disperses. Two feet of open space around the unit is plenty. For a bedroom, the nightstand or a wall shelf opposite the bed gives the most even coverage; for a home office, a bookshelf or desk surface near the door works well.
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 Diffuseur de parfum 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 Diffuseur de parfum 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 Diffuseur de parfum 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 Diffuseur de parfum 2 delivers a dry, consistent scent on a programmable schedule.
What’s the warranty and return policy?

The Diffuseur de parfum 2 comes with a one-year limited warranty covering manufacturing defects and pump performance, plus our 14-day risk-free return. If you don’t love it within 14 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 Diffuseur de parfum 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.
